A friends daughter got the listed scooter wet, can anyone tell me the minimum voltage to make this scooter motor turn just for a test? Also is there a way to test power coming out of the controller going to the battery? And last is it more likely, if the battery is good, that the controller is bad before the motor? Or where else should I look for the issue. Apparently his daughter ran it through a puddle and it hasn’t worked since..any help is appreciated, I’m a Tinker I like to fix things if I can and they are nice people so there is no charge either way.
 
Jetson states that the battery is 36V 6aH. That usually means that the motor voltage at full blast is similar. Test the battery output first. If it's in the 36V range, then test the motor input with the throttle on full blast. If that's not in the 36V range, then the controls or the controller are bad.
 
Specs say 36V battery. That means a max voltage of 42.0 V at full charge. The scooter will run til the battery gets to around 30V. Then the scooter shuts off. The battery has its own shutoff that triggers slightly under that, as a fail safe. Running a lithium battery too low can damage the cells and create a fire hazard. In short, the scooter can operate anywhere above 30V,

All the electronics are under the floor boards? Start there and make sure no standing water. I would expect Jetson to do some water proofing. If wet, unplug battery and let everything dry out. If water seeps inside the aluminum control box, it will fry the circuit board. On my ebikes, which were DIY conversions, I lost a few controllers from water til I took more care to protect them from splashes.

If it has an LED/LCD display, look to see that they power up.

Yes under the floorboard, and thanks I’ll start with a new charger to get the battery up to full charge and go from there

Thank you, where would you suggest I access the motor input, at the controller or take the motor out and test that?

The display lights power up but rapidly fade, as the battery only has 15v. I bought a new charger 42v and tested it and it’s putting out 42v, but when I plug it in the scooter and test the lead, it’s only putting out 15v, reckon the wiring from the plug is bad?

Unplug the controller from the battery, if you can. Then measure the battery voltage at the plug with and without charger plugged in. Want to know how battery is behaving with no load on it.
 
jlw, is the charger telling you that the battery is charged?

I’ll bet there’s standing water down in the base of that thing. Can you flip it over? As Harry said, take the battery off and make sure it’s all dried out before doing anything else. If something is shorting your battery, that’s kind of dangerous. Be careful. Water is the enemy.
 
Battery is out of scooter, base is open and has been for a couple days, I was testing the battery where it plugged into the charging port and was only getting 15v at the plug, battery totally unplugged is only 15 v after being on the new charger 12 hours

charger light stays green, but I’m not familiar with it I do not know if the light changes color or not, it’s one off Amazon
 
I’ll send a couple photos in a bit of me testing and where, I really appreciate all the input, hopefully this will also be helpful to someone else at some time
 
Hmm… The battery may be out of its minimum range, jlw. I’ve seen people revive their batteries using some manual charging devices (i.e., a slow ramp-up of voltage and constantly checking for heat generation). I can’t advise you on how to do that though. Maybe someone else can help. Sorry! Good luck!
 
I’m befuddled as to why I have 42v at the charger end but only 15v at the other end that plugs into the battery

No worries it’s all about learning thanks
 
Every photo I try and attach is too big but I did find out that when the charger is unplugged it’s light is green and when plugged into the light is red, it is only putting 15v out at the battery, and the volts vary at just the charger plug itself, 42 dropping to 16 but I’m not sure if that’s normal or not
