Noco GB70 repairs: one won't jumpstart, the other's completely dead

[@thaomai5653]

Great fix. Cool of you to give a shout out to sos... I'm trying to get mine working too. Cheers.

[@RODALCO2007]

What a poorly designed casing for an overcomplicated jump starter . Everything slammed in that case together and almost impossible to repair. The risk of puncturing a Lithium cell and causing a fire is always there. I bet the Copper looking alligator clips are not strapped and not copper either. 2000 Amps claim? doubt it. Great video anyway and fault analyses. Great effort to unsolder and test the SMD components. Did you test the actual jumpstart capacity?

[@AintBigAintClever]

I didn't test them as jumpstarters, just fixed them and gave them back. I've not heard any more so I assume they just do their job now, the person who owns them buys and sells cars so they probably get a reasonable bit of use now they work.

[@RODALCO2007]

Thanks for your reply.@@AintBigAintClever

[@Ade-T.C.S]

Well done pal another great video.

[@gwbenites]

I have that heat shrinked wire on my Schumacher jump starter too. It was just stuck under the rubber pad that sits between the battery pack and the case.

[@j.p.1576]

NOCO is all marketing. I have two and they were both junk before the warranty expired. The cost to use the warranty is more than the cost of a competitor unit.

[@boketto888]

Excuse my ignorance but at the end why when you press the power button on the genius does it power off both jump packs?

[@AintBigAintClever]

Towards the end I've got one providing power to the other through the red and black cable. Also if my finger is on one pack, watch what my thumb is doing on the other.

[@boketto888]

Thanks for the reply. Oh to be fair I didn't have my glasses on but it's a lot clearer now haha ​@@AintBigAintClever

Very interesting. Thank you!!

My Noco GB70 have never worked, just runs the light and make the click click click sound. In the 5+ years I have had it and 20 - 30 start tries it has never started anything at all...

[@julesviolin]

Great work although I don't know how you manage on SM boards with those huge fat meter probes ! I use needle point probes to prevent shorting between pins. Also I can highly recommend copper solder wick for desoldering. It's quick and easy 👍👍

[@jeffroe2523]

Gr8 video. Are you up for repairing my 70 and so where are you based. I'm stockport area.regards Jeff

[@techfournine2730]

Well done sir!

[@ramiretz]

crazy how many of those (premium products) totally Fail.......... i see so many Nocos Fail... sad very sad. love how you repair those things !!!

[@dingbell5498]

Got a virtually unused gb70, started a motorbike twice, plus a Skoda. That’s it. Tried on a Land Rover which turned out to have a faulty battery, and it won’t work since then. Switch’s on, indicates charged, torch works, but won’t start anything. Any ideas, or repair?? Noco don’t want to know, just offer another at a very slight negligible discount.

[@ShyRage1]

Torch is the flashlight?

[@GORE-pc5oj]

Well done great job.

[@ferrumignis]

If the 30A fuse blows then something has shorted out on the control board, and this fuse blowing prevents a potential fire. It's a very sensible design decision to not make this a user serviceable part, just imagine what would happen when some idiot invariably shoves a piece of thick copper wire in to stop it blowing... Some would say this is a self limiting problem (Darwin award) but it would open the manufacturer to litigation.

[@warrenhawthorne1496]

I also have a GB70 with exactly the same issues, working torch, but wont turn on with the main switch. I did notice prior to it not switching on at all that the switch became very temperamental. Do you have she specs for the switch that you replaced (size/height) as ive seen them on ebay/amazon, but am not sure of the size. Thanks Warren.

[@AintBigAintClever]

I'm afraid not, I rummaged through a tub of switches and buttons to find something I could use.

[@ShyRage1]

When you say torch, do you mean the flashlight function? Also, did you find the correct part? Link to it?

[@mattmoreira210]

14:55 you’re not supposed to replace it?! Fuses are the last components to blow when semiconductors are overloaded. Maybe the fuse is there so things don’t catch fire *after* the semiconductors have gone short-circuited.

[@AmperaService]

I just bought an gb70 advertised as new but without charging cable,it won't charge or turn on,measured the voltage at the clamps while pressing the on button and I get 0.7 volts. Will try to open I up and connect to a power supply, anyone know what size are the triangle screws for the body? Thank you for your video and you got a new subscriber!

[@AintBigAintClever]

The one I've used in the photo is fairly small. Something like www.amazon.co.uk/dp/B09BQM21KH should do.

[@ELEVOPR]

Mine shuts down when once it is in override mode and I crank my car to start the Noco Boost Shuts down. Mine turns on, shows its charging and it is now at 100% if I use override mode then minute I try to crank my car, GB70 Just shuts down. Anyone ever have this happen to them?

[@AintBigAintClever]

Sounds to me like the battery pack itself could be defective? You know when a car battery has a weak cell, so it may appear to be fully charged but the voltage collapses as soon as you try to do anything "big" with it like start the car? Could be that, with the battery voltage quickly collapsing to below the point where the GB70's processor thinks the pack is fully discharged and shuts down to prevent overdischarge. I could be wrong of course, but that's my suspicion anyway.

[@ELEVOPR]

@@AintBigAintClever Thanks for the tip. Can I check that with a Multimeter? Can the Battery Pack be changed or replaced? Thanks again for your response. I have the older GB70 with the much thicker Cables.

[@AintBigAintClever]

@@ELEVOPR I think you'd have to dismantle the unit and put a multimeter across the balance wires, see if any of the cells keel over when jumpstarting. I expect it's a custom cell pack so if the cells are gone it's a bin job.

[@randacnam7321]

The 1.3V with no battery could also be a safety thing: if the clamps are shorted, that will drop to 0V and thus it knows not to try closing the main contactor. If instead it sees 9V to 11V, it knows its connected to a dead battery. Same with if the polarity is wrong, as it will see a negative potential and thus not close the contactor.

[@colindejager1250]

Enjoyed that detailed look-in...

[@bradday2823]

Sorry forgot to mention, great full detailed video showing fault finding at its best.

[@g.c.3339]

Fuse need not be accessible if it is to protect against a two-fault scenario that may result in excessive heat. The probability of those exact two faults (say by component failure) is likely very low, but the need to protect against overheating is a safety function if, in a rare case those two specific faults do happen. That is a common design approach and reflects a thoughtful design. If a fuse for that purpose ever opens, there would be other parts that have failed - so making the fuse user-replaceable would be useless.

No one else on KZbin has this type of GREAT CAMERA ANGLE !!!

I think Naomi Wu has some better camera angles :)

[@roberttaylor5880]

I am on my 4th one of these in 2 years Everyone the same fault, will not charge above 25% Luckily i brought from Amazon and they have sent out a replacement free even though its past its 30 day return window

[@julesviolin]

I would expect a 12month warranty though just like a shop !

Can't recharge junk

Torch

[@mikef3324]

Where are you bud, sounds like the UK. I've got a faulty unit that won't charge from the socket. I can't diagnose what component is faulty and wondered if you could help. Thanks

[@mikescalise3913]

Great video I have the Genius boost that seemed to be great for the first few years I've owned it. About a year ago the cased separated but it still worked like normal. just recently when i needed it it was dead. I was able to charge it use it and the next morning it was dead again, so now it will charge but will not hold a charge for any length of time. Any ideas?

[@donphelan5674]

Watched your video I have the same problem with my charger would you be able to fix it I live in Ontario Canada and I would ship it if you can thanks

Hi.i have noco gbx75 not power.baterry is 13,5 v.but no any leds turn on.can you help me?

I dropped my noco gb150 and it doesnt wanna stay on and charging it takes forever where can i send it to u and how does payment work?

[@triode1]

Sorry, but this video was very confusing to me-I’m not very 'electronics' savvy!

[@en2oh]

does anyone have the size / type of 12v male connector used with these products?

[@vornamenachname1965]

Great video! A thousand times better than netflix! I am addicted! Thanks!

[@ML-zq9hs]

Great video! Thank you so much. Makes me believe I could fix my gb70 should it go bad. Nice troubleshooting technique.

[@ShyRage1]

My GB70 flashlight works but power button does not turn on

[@williamhsteele]

What size bit was that?

[@rpasco9352]

You could have tested whether the PB switch was bad by simply shorting the two N-O contacts to simulate what a good switch would do when pressed. To simply replace the switch without doing this was very shortsighted.

[@AintBigAintClever]

Some might say that to poke around shorting pins in a unit with a high energy ithium battery would be very shortsighted.

[@ShyRage1]

what setting on voltimeter do you have it on?

[@magna116]

Is there an internal fuse on the 12v auxiliary output port?

[@andreasdahl717]

Hi. great vid. Would it be possible to put the jumpercables facing the other way so the cables face the same way as the flashlight?

[@AintBigAintClever]

It's difficult to get the case closed as it is. If you freeze-frame at 7:18 you'll see that the mouldings aren't symmetrical and would require some modification to get them to fit in, even if the cables themselves can be turned round.

[@davehenderson6896]

Would be cheaper to just buy a new one.

[@darrensmith8800]

Great work, I have one that went flat, and now it won't charge or do anything, is tyat something you could fix please. I have been in contact with noco as its just over a year old but I havnt got the receipt any more.

[@brianyoung4900]

There's a video where they charged using negative on usb c positive on pos jumper cable

[@ShyRage1]

Can you post the replacement on and off switch for the gb 70? I'm looking for it.

[@AintBigAintClever]

www.mouser.co.uk/ProductDetail/CUI-Devices/TS04-66-65-BK-100-SMT won't be too far off, this one's got a 3mm stem for a total switch height of 6.5mm There are others in the range, just make sure you get the 6x6 ones.

[@YorkerY28]

Upside down?

[@cougnut1968]

What size are the screws in the back

[@AintBigAintClever]

Not sure. I used a tri-wing screwdriver that's designed to open a Nintendo Wii. Both chargers are now 60 miles away so I can't check.

[@TheBmwslider]

Anyone know what the 2 main power relays are? Thanks

[@AintBigAintClever]

Unfortunately although the relays are visible at around the 34:50 mark the camera never seems to focus on them. Worth checking some of SOSfix Electronics' videos in case he's managed to catch a good image of one.

[@TheBmwslider]

@@AintBigAintClever ok thanks will take a look

Hello mate, I also have one of these Noco GB70 that doesn't work! gutted! Do you provide a repair service or know where I could get this booster repaired please.

[@AintBigAintClever]

I don't, sorry (on both counts). There's a fella in the US who does them (the one I linked to in the video description) but I've no idea how much he charges or whether the postage costs (albeit surface mail due to lithium battery) would make it unfeasible.
