Trying to FIX: Razor Crazy Cart Shift

[@tomthebadasscat]

Hey Vince, don't take this personally but the best bit is seeing the kids having a blast on something you have revived. 😁👍

[@Tronicsfix]

Love those carts! Nice working diagnosing the faults!

[@Mymatevince]

Thanks Steve, sorry I haven't watched your vids recently mate. I have been mega busy. Looking forward to catching up on your 3 Part Switch vids.

[@potstella]

That why you need a mate like Vince, just popped in and trying to fix stuff😂

[@GadgetUK164]

Great stuff Vince! Regards the LED behaviour difference between the chargers - one of them perhaps has a failed green LED (so it still works, but the green LED doesn't light). You can probably swap out those batteries pretty easy - look on eBay for 12V Lead Acid Alarm batteries - check the mAH rating and physical dimensions. EDIT: Assuming the ones on there are lead acid.

[@Mymatevince]

Thanks Chris, the LED may well have failed as it was still outputting 28V. When I watched the video back I spotted underneath one of the battery packs that it had a sticker on it. I didn't notice it when working on it as I didn't look underneath but I presume the info would be written on there. The batteries are only $39.99 in America but cost £47.99 over here when advertised as Razor batteries so the alarm batteries might work out much cheaper. As always thanks for all the support and advice :-)

[@mypersonalbiblestudies]

Just as others have stated, I would check the voltage drop of the batteries individually as one may be bad and not both. Additionally sometimes these types of batteries will have a resistor that will act as a thermal type fuse. It could be a battery is getting to hot under load and cutting out. Great video again!

[@Mymatevince]

Thanks Shawn :-)

[@YommyRawr]

test the batteries individually, not in series. you will probably find only one is defect.

[@PottsTheDruid]

THIS! 1000 times this!

[@vitor900000]

Yo. One of the batteries on the packs could be internally shorted and acting as a resistor causing the pack to discharge. To be sure separate the pack and measure the voltage of each battery. If the voltage is too different the lower voltage one is dead. If they are connected in series you only need to buy one battery but if they are connected in parallel its complicated... They need to have the same capacity and be balanced.

[@ftrueck]

As he gets 24V on the good one, you can say this is a 2S pack of 12V batteries.

[@Mymatevince]

Thanks Vitor, I tried to work out if it was series or parallel off camera but the first battery had 2 red leads (from memory) so I couldn't work it out. I think as Florian Truck mentioned it is probably 2 x 12V in series. The battery looks like it had a label or printing on the bottom which I missed when originally filming. This would have given me the info if I had seen it in time :-)

[@vitor900000]

​@@Mymatevince Check the polarity of the one with 2 red leads with your multimeter. If they are in series and one is giving much less voltage than the other all you need to do is to buy one 12v battery with similar capacity (mAh / Ah)

[@heatedgamer2931]

It wouldn't be a @My Mate Vince video if you didn't at least break something to repair it lol. Great vid as always mate, would love to see more home repairs and older consoles, btw your trying to fix video on the washing machine helped me fix my washing machine as i didn't know about accessing the bottom of the washing machine and it turned out a penny was blocking the vent fan.

[@AcornElectron]

Well, I guess there are some advantages to being up at 5am. Keep up the good work fella!

Haven't seen this video either, seems KZbin is recommending My Mate Vinces older videos now :)

[@typicalpctech6674]

Sealed Lead Acid Batteries are notorious for going bad. Often these kind of toys are left plugged in for weeks at a time, or drained completely dead, then never charged until the kids want to play with them again. During winter months this is terrible scenario for any Lead Acid battery, as you want at least a trickle charge during the winter/non-use long periods. Which also causes issues, but possibly not as much as a problem. Drained and left in the shed during cold months, then charged probably killed a cell. Very common, even in cars.

[@typicalpctech6674]

One of the batteries might be ok, but with 1 new and 1 old battery, it would just fail again sooner then if you bought just the 1 battery. If they were only going to enjoy it for 1 more summer, I'd say 1 should do, but if you want more use, buy 2, then story the batteries in warmer weather when not used for long periods of time (tip for the original owner), or anyone that doesn't already know.

[@Mymatevince]

Great advice A2Z Kids. Thanks for sharing the info :-)

[@typicalpctech6674]

@@Mymatevince no problem, been enjoying your vids for a while from the states, very very helpful!

[@lubomirrolko1967]

It is annoying when the battery is faulty. There's really nothing you can do about it. Nice video, even though I didn't expect it today. well thank you

[@Mymatevince]

Thank you :-)

[@SPEXWISE]

It's basically a dodgem. That's how the dodgems work at the fair except dodgems don't have batteries, they get their power by connecting a swipe arm to an electrified ceiling mesh and also being grounded to a conductive floor.

[@catcam]

Dear Vince, you can always try to find used UPS batteries on local ads or flea market. Again tnx for great content.

[@RandyDarkshade2]

I have followed your channel for awhile, you are getting really good at fixing thyings. :)

Hey Vince, just wondering how you would have force charged it & what you would have needed? Tks so much

Those little cars are like dodgems without the bumpers. Futuristic kid fun . Well remember the dodgems and being told off for actually trying to bump friends in their 'bumper car'.

[@wanjockey]

I have a LiFePo pack for my ebike and it has an over current protection that will cut off the voltage from the battery if I give it full throttle without giving the bike some assistance pedaling first.

[@andersmmvfc.8376]

You need to sleep! Thanks for another intresseting video!

[@BakedPrawns]

Hi Vince. I’m an OR engineer. I’m just wondering what part of telecoms engineers you are/were involved in?

[@Mymatevince]

Hi, I used to be a customer service engineer. Worked mostly from PCP (cab) to house but sometimes had to do exchange work. I was unlucky when I started as customers were getting 2nd lines for dial up internet....Every job normally involved running a new dropwire, internal cabling and the proving the pair back to the cab. Years later nearer the end before I left I used to do a lot of fault finding and I loved doing that :-)

[@Puremindgames]

WOOH! Yorkshire!

[@anthonyhenryhoover9278]

I had one of these but the next one up so junior one that got up to 12MPH had no problems with it apart from a burst tyre that was an easy replacement

[@defiantgsxr]

Heck yeah

[@Razgromable]

Vince, thats a hall sensor, the metal plate is a magnet, what is weak at the beginning, getting stronger till the end. / There is a chance, that only one battery was dead only.

[@Mymatevince]

Thanks for the info on the hall effect sensor. Yes, I wish I had separated out the batteries to see which one was faulty. Others have said they might be just alarm batteries so replacing one may have been cheap. The problem here on this vid is I was without my normal tools so I was limited to what I could do :-)

[@Random_4400]

Those are lead acid battery's 12v each in series so = 24v if one of them goes under 10v that means the cells (or sometimes just one cell) in the battery are damaged (usually the voltage of a flat 12v lead acid battery is 11v) so 19v divided by 2 is 9.5v and because the voltage gets too low the charger won't recognize it hence why it wasn't charging

[@cd1315]

Sounds like You are reving a vacuum cleaner.

[@TheJeracuda]

i'm curious as to whether or not you could possibly swap the accelerators of the two vehicles

[@TheStanHill]

The affordable electric vehicle we deserve

[@jasejj]

I assume these are lead-acid batteries, if you can find the right size it's probably possible to pull the pack apart and replace a single cell for £10-15.

[@oscarmarfori613]

Something wrong with the pedal, definitely the pedal, Maite

[@RETROSLOTSBLACKPOOL]

[@chillenchilla4]

[@SuperCloneRanger]

The 3 leads coming off the sensor in the pedal makes me think its using a hall effect sensor.

[@tsmithurst]

One battry might be lower voltage charged than the other therefor when you charge both battrys in series one is left not fully charged get a 12v charger to each battry making sure they are both same voage befor charging in series one battry might still be weak but it might be worth a try befor ditching both battrys

[@nismizaini2692]

Where can I find the battery?

[@tomsnook8930]

is the battery dead

[@nathanmead140]

That other battery could be taken apart and hooked up to a car charger for an hour and it might fix it

[@Mymatevince]

Yeah, it would have been nice to get a charge into the faulty one to see if it kickstarted it back to life again :-)

[@tobadsosad1040]

So I got one for kids worked great for two weeks enough power for even my wife to ride. Now at full charge the wheel with motor turns but any resistance stops it. And doesn't seem to spin as fast. Motor issues or battery. Could use guidance

[@tobadsosad1040]

Tested battery with multimeter and battery reads full charge

[@BoCaRdrecovery]

Put a drop of glue on end of blue switch to take up slack of warn parts

[@adiposerex5150]

Sounds like my food processor🙉

[@3ddirtbike704]

Hi mate if you Put one battery from the good KrazyKart into the faulty one and there should be one faulty one and one good one and then that will trick the charger and charge up the faulty one I have done it plenty of times and it has worked But I haven’t uploaded a KZbin video how to do it yet

[@Mymatevince]

Oh you mean separate out the pair of batteries, so each pair would have one good and one bad battery. Yeah that could have been an interesting way to get them charging :-)

[@3ddirtbike704]

Yes it Should work it has done for me mate Give it a go and make a video on it so Other people can learn from it (:

Hi I will Be Making a KZbin channel doing similar stuff as you as well Very soon and I will Keep you updated on it as I Love doing things like that 😊
