Nice..it’s a good fix I will remember, you are correct I cannot find a good rv repair shop that will fix items at this level. Always $150.00 hour and all new parts. If they knew the product they could diagnose this issue in 10 min, total repair it 20 min hence no one will do it that way. Old school is better long term. Do it yourself & you will never go wrong, We may do it twice but you will get it done.

Put new batteries on my trailer today, installed a renogy battery monitor over winter. Plugged in shore power and I'm seeing 13.6 volts but less than an amp going to charge the battery. Looks like I'll be pulling the converter in the morning and doing some testing, huge thank you for the video.

[@RotoCityTech]

Thanks for watching. 13.6 is pretty normal and if it’s only taking an amp my guess is the battery is full and the converter has gone into absorption mode

At 4:30 that would be the continuity setting of your meter, the real basic ones will tie it in to an ohm reading setting like the walmart meters. Some of the fancier meters have a strict continuity setting. Good way to still test those. Especially the blade fuses for automotive.

Just replaced a $377 converter and wouldn’t have (well don’t have) the understanding of electricity as you do. Have to give you kudos for getting it fixed! I mean I wouldn’t even know what to call that part you replaced to buy another. The fuse I could replace but that part...nope.

[@RotoCityTech]

Thanks for taking time to comment and watch. Well ultimately you just need it to work so having a new one is probably best. Especially when you’re out camping! Thanks for the comments tho!

[@garyconway439]

Thanks Hank! In my case I could see both of the 200V 680uF caps were bad, the cases had heat damage/bubbling, and the metal ends were swollen out a bit. I ordered replacements from China on EBay as what I found in the USA would take longer to get and cost more. Plus I replaced the fuse with an Axial Ceramic Time Delay Fuse, 6x30mm, 15A, 250V from Amazon. Nearby the caps was a brown area which also looked liked heat damage at R49, a 1470ohm resistor. I lifted/desoldered one end and it measured fine, so resoldered it back down. Happy to say it worked like a charm, RV lights are now working, and I expect the batteries will be getting charged. FYI this came about because I connected the plug to 240V, thinking that the RV 120V 30A outlet was just like my shop 240V 30A outlets. Oops! that was a stupid mistake, but all fixed now.

[@RotoCityTech]

Wow! That’s awesome that you were able to discover all of that and fix it. It’s so awesome that I continue to get people having such success fixing these converters even years later. Good work

[@jacksondaigler5145]

Thanks @garyconway439 I did the same thing and hooked up to 220 and heard a humming and trip. Went inside saw a 5 amp breaker tripped. Reset the breaker and smoke was released from the capacitor 🤦🏼‍♂️. Yep I deserved it. but hopefully I can replace the caps and fuse like you to minimize my stupid taxes. Im worried I damaged other components but it sounds like you got lucky. I even turned the battery on and the AC, fridge and tv worked just before being drained. Hopefully my follow up is good news too.

[@garyconway439]

@@jacksondaigler5145 The good news is that the 200 volt capacitor and the 15A 250V fuse are in the power supply, ahead of all the other components. I expect the 240V over-voltage on the 200V capacitor caused it to short out internally and this is what blew the fuse.

Thanks!! It looks like the same unit in my 2018 Surveyor.

[@RotoCityTech]

Happy to hear you’re going to take a look! That’s a strange problem to have tho with no shore power coming in and only 12v. I’d also start tracing those wires connected to the 30amp plug. Good luck and keep me updated!

[@karlnyman2811]

@RotoCityTech when I opened it up there is a bar with wires going into it with about 7-8 Set screws. One of those set screws came loose and the wire bounced around and the wire jacket was crispy. I snipped off about a half inch and tightened the set screw correctly and VOILA👍🏼👍🏼 All good!!

[@phillybrc]

So, if I am plugged into shorepower(120v) would this stop my 12v devices from working properly? That s the issue I’m having.

[@RotoCityTech]

They problem it’ll have is that while plugged into shore it will not charge your battery so once your battery dies all the 12v stuff will not work

[@yobinesjl759]

That was very good my friend because if you call the dealer they always want you to take the camper and they want your money that’s only what they want

[@RotoCityTech]

I agree with you. It’s unfortunate that that’s the way it happens. One of many reasons why I just try to do most by myself and with help from others. And the Internet. Lol

[@indyzmike]

I have a pair of WFCO 75 amp converters with the same problem. Parts are on order. I would suggest replacing both capacitors because if one is old and dried out, the other one is not far behind.

[@RotoCityTech]

[@mk_paper_bird]

Good vid man. Unfortunately I had to find out the hard way like you did with the exception that both of my capacitors are blown but the F1 was fine. Inverter fan kicks on for about 5 seconds before cutting back off, if you pull the top “reverse battery” fuse. I’m assuming it’s because the capacitors can’t obtain and distribute the required voltage and it’s just taking the whole unit a few seconds to figure that out. 🤷🏼‍♂️ either way I’m 17 days into a healthy and junk food free lifestyle and I have my heart set on a Reese’s and a Vanilla Coke so I’m done for now. Thanks again for the video! Peace and love from bama

[@RotoCityTech]

Awesome! Happy to help. Thanks for watching and commenting.

[@markwisner3972]

Good video. What probably happened is the reverse battery connection blew the orange fuse but not after damaging the cap and the internal fuse. I would suggest replacing the other cap. It may not have been damage to the point of failing but it was probably stressed more than it should have been. It will eventually fail at the worst time. To state the obvious. if you drained your batteries, they are probably damaged. Where did you get the cap and fuse? We use to have radio shacks but they are long gone.

[@RotoCityTech]

Yea I think that’s exactly what happened. The battery didn’t fully drain and it has worked great ever since so I don’t think it got damaged. I do have another capacitor to replace and that’s was on the list of things to do. I believe I just searched on eBay and Amazon for the fuses and capacitors with all the same numbers. Too hard to find locally these days with all those electronic stores closing. Thanks for watching!

[@Encompdev]

@@RotoCityTech what likely happened - you accidentally connected your power to 240V instead of 120V. Besides fuse and capacitors there should be a a circular component called Varistor, right after the fuse, which is designed to make sure fuse blows up if a high voltage is connected.

[@samuelvincent5602]

@@Encompdev not sure where I would have found 240v tho. I’m pretty certain it was hooked up backwards when we hooked it to a vehicle because the battery dies and it was pitch black. Either way this fixed it 👍🏻

[@0ptimal]

Nice. My issue is similar, but a bit different. On shore power only(I don't use a battery at all), my AC is getting through to DC, but if it gets cold then the DC output is somehow restricted or flickery/faint.. So when it acts up my lights(fridge, anything DC) will either blink on and off at a tic toc pace, or they'll dim very low and a loud steady beeeeeep will sound(I've heard it's a low voltage signal). But, if while this is happening, I use say the microwave, or toaster, or anything AC current thats pulling a lot of power, the DC will work fine, but only while that AC appliance is used. It's like something in the DC output side, some component on the converter board, is shorting out or shrinking when it gets cold, not allowing the current to flow properly. And using an AC appliance somehow shoves the current through so it operates as it should.. lol idk. Only acts up when it's cold, it it's warm outside there's never a problem. Probably just gonna buy a new one but I just think it's prob something simple and cheap, so trying to see if anyone has dealt w this specifically

[@RotoCityTech]

Thanks for watching. Hmmm yea this is strange. I’ve never heard of this before. It does seem like something is throttling there power for some reason until an appliance forces juice to run thru. I’m sure there’s is a way to test all this but I don’t even know what meter you’d use to try and do that. These converters are not too expensive so I’d say yea just get a new one to replace and then start messing with the old to see if you can find anything out. Best case is you have an extra converter in case the other one messes up

[@bmc81]

You lucked out. I blew up three of these puppies because of bad power. Unable to work on the boards as they were toast. So had to buy the converters online. The one I have is around $170 and I had to install. Yours is in a great location. I had to completely pull the panel out as far as it would go and hang it with a rope to a handle above. The converter is behind the panel on my Fleetwood motorhome. That sucked doing this each time. Thanks for the tip. Wish mine would have been that easy.

[@RotoCityTech]

The other electrolyic capacitor is getting domed at the top as well. That is a sign of failure. You should have went ahead and replaced both. If not, other components could potentially fail if it goes bad too. Just a heads up.

John Curtis thanks for the heads up. Props my something smart for me to do here in the off season. Thanks for watching.

[@johncurtis1963]

@@RotoCityTech Yes! You did a great job on the replacement. The electrolyte compound inside tends to expand when its drying out causing the capacitor itself to get bigger. Mostly happening to the top. Although, I have seen it happen along the sides too. Cheap insurance, you may want to look into replacing all the electrolytics since they do not cost much and one of these converters are a couple hundred dollars. I am into radio communication. So I ran across your video in my curiosity if I could use one of these units as a power supply, as I need something that will produce 50 or more amps. I found one of these on ebay. It is on its way so time will tell. I just hope this unit has enough filtration in the circuitry (since it is not ordinarily used for this) to not produce noise interference in the radio I am using it with.

[@stewartbrands]

Awesome clear explanation. Just the facts. Thanks.

Thanks for watching and commenting. I appreciate the feedback

[@matthewcramer7391]

will my converter make my ignitor not work on my furnace if it is bad?

[@RotoCityTech]

Thanks for watching and commenting. I don’t see the relation between the converter and ignitor. My guess if you are having furnace problems it is in a safety lock situation. This happened to me a couple months ago. I just turned it off for a few minutes and then back on to reset the timeout

[@matthewcramer7391]

@@RotoCityTech yeah I tried that and got nothing. The blower kicks on but you can't hear the igniter then after 20 seconds it shuts off

[@RotoCityTech]

Hmmm weird. Maybe there’s an issue with the propane or perhaps the ignitor is bad. Hard to say without seeing it in person.

Thank you bc my power went out, and I know it has something to do with that converter. Thank you for the video gonna try this today.

Thanks for commenting! I’m sorry yours is having issues but I hope you can figure it out today!

[@melissapeck3089]

Hi Latoria Martin I am just wondering if you got your converter working.

[@Plumblikethat]

Having the same problem So I’m going to give your advice a shot hopefully it’s that simple thx for the video Will give update

[@RotoCityTech]

Thanks for watching! Yea let me know if it fixes the issue and good luck!

[@melissapeck3089]

Hi Two9 Did you give er a shot?

[@peacelovehomestead8361]

Me again. When you took the board off to replace and solder the capacitor and fuse, did you have to disconnect the wires or just leave it hooked up and wrangle it into a good position to work on it. I've watched other videos in which they actually replaced the converter and there were lots of connections with wires that looked a bit too much for me. But if I test and find the problem and can just flip it over with the wires still connected, I think I can do this myself. Thanks for your help!!!

[@RotoCityTech]

Yea I regret not getting that part filmed. I just disconnected the cables at the battery and then got it in position to solder it right there on the floor since it was just the one fuse. Good luck!

[@littlebigcreatureful]

We just went through a hurricane and lights are out so I went back to my RV and my battery was completely dead . I replaced it with a new one but a day later the new battery wasn’t charging it read 10V what could I be looking for to fix this issue I’m basically boomdocking till we get power around the area I’m in

[@RotoCityTech]

Sorry to hear this. I would first look at the two 40 amp fuses in your box and make sure they are good. Remember tho if you are boondocking the battery won’t be charging unless you have solar panels or are plugged into 30 amp service

[@jbaz964]

Does the power converter have any other fuses? I was expecting it to have 2 external 30 amp fuses on the back of the box.

[@RotoCityTech]

Thanks for watching. As far as I know there are no more other than on the board and then those two 40 amp fuses printed out. There might be one right after battery behind the frame I just can’t remember now

[@jbaz964]

@@RotoCityTech I checked and there is not. Thanks for the video. It's a good one.

Where can you buy the capacitor that you replaced? I need one for mine. Thank you!

[@RotoCityTech]

Thanks for watching! Check the video description and I should have it linked.

[@f150bft]

Same trouble here. Mine is older and does not have the slow blow fuse, but those two white rectangular blocks are super hot and turned the circuit board dark brown

[@RotoCityTech]

Oh dang… I’m not sure on the older boards if maybe the fuses look different or not. Might be worth just getting a new board for you or even upgrading to a modern one. Thanks for watching!

[@f150bft]

@@RotoCityTech I went and looked again.... it does have the fuse after all. It was covered up with some white goo and it checked good. I'm going to replace it with a Powermax unit 55amp I think.

[@RotoCityTech]

Ahhh I see. Well yea I was looking at that converter myself at some point

[@johnmayes9222]

My converter keeps clicking and my lights is flicking bright and dem when hooked up to ac power ? Any ideals ?

[@mallardimichael1816]

That's just what happened to me. What did you do?

[@TxRiverElf]

Great tracking! I really appreciate this video. I have the exact same model and my concern is that it does not seem to ever go into bulk mode... when it was my impression that it did so, periodically, just to keep the batteries truly charged?

[@RotoCityTech]

Thanks for watching! I don’t think I ever checked that it went into bulk mode specifically. After this fix tho it seemed to operate like it should so I would assume so

[@bukit2361]

Thanks man, great video.

Hey nice video, I replaced mine a long time ago. How would you discharge the capacitor over time? Turn off the breakers & just let it sit there for hours?

[@RotoCityTech]

Thanks! I’m really not sure. At the time of this video I didn’t really know that was needed. I’m guessing it discharged y just sitting there. I need to look up some info on that

[@kingtitan2051]

1 of our capacitors just blew. We have a 30 amp trailer. Did you know the capacitor specs for 30 amp. I dont see it anywhere. Great video Thx.

[@RotoCityTech]

Thanks for watching! If you check the video description there is an Amazon link for the capacitor that I purchased.

My capacitors have no markings. Just trying to find the right ones.. Thanks.

[@RotoCityTech]

Yes we have 30 amp service as well.

[@JoseMartinez-vs1fg]

Thanks!!! I've already done all the troubleshooting... how do I change that fuse myself?

[@RotoCityTech]

I wish I would have re order the repair but I didn’t. 🤦🏼‍♂️ it’s pretty simple tho. Just heat up the solder underneath the board to the fuse that is blown. Pull that fuse out and then insert the legs of the new fuse in and solder it in the back side back to the board. Should be good as new

[@MotoJunkies-ll5dd]

Thanks for this! Just checked mine on a new to me camper and it is blown. It looks like 250v 5A fuse, correct?

[@RotoCityTech]

Happy that you found the issue! If it’s the same converter then maybe so. You can open the video description and it’ll have links to the parts. Thanks for watching.

[@Drew79]

Thank you for this video. I have the converter in my new trailer. All was good until our third trip and the converter fan kicked on and the battery got really hot and was leaking. Could you recommend anything else I could check on this converter or trailer?

[@RotoCityTech]

Thanks for watching. Hmmmm sounds like there is a short somewhere cause that to happen. I’d start by trying to look at all my hot connections and make sure they are good and then the ground as well. It can be difficult to find these gremlins tho. The battery leaking is a big problem

[@roldaventate272]

Question why do u have 2 40 fuse when the Manuel for the 8900 says only(2) 30 max?

[@RotoCityTech]

Good question. Those were in from the factory so I am not sure. I can’t recall ever looking at the manual either.

Hi there , thanks for the video, exactly my problem. However where do I buy those parts for replacement?

No problem I’m glad it helped! Check the description for links to Amazon. Hopefully everything is still available. I’ll double check as well. I just looked and the link to fuse works but not the capacitor. I’ll have to find that again but if you take it apart you can look at the part number and search it

This is a great video - I have an issue that can’t seem to find the issue - My camper is having an issue where I am getting 110 volts on the left side of panel, I am not tripping the 12 volt fuses on the right side, but I am tripping the two 30 amp fuses that are in the middle of the panel. Could a converter be causing the fuses to blow? Or do you think It could be a ground wire?

[@RotoCityTech]

Thanks for watching. Man, that sucks you’re having this issue. Seems kind of strange to me. I’m not super knowledgeable but I do think it seems like a ground issue if it’s blowing those in the middle but not the 12 amp ones. Make sure the fuse labeled for reverse polarity is good because i had an issue with that and then check right behind the front frame portion there are some breakers that might have come loose. But now that I think about it that’s all before the board..... hmmmmm I’ll think about it some more

[@timlist4173]

Did you find a place to get a wiring diagram and parts list of the converter?
