So it's not a custom build - it's an ev warrior - but i didn't see any place in here for that specific model so I thought I'd post here.
This thing just quit working correctly Wednesday. I'd taken it all over town before, and then the power started stuttering - like there was a short somewhere. I thought it was the brake lever kill-switch at first (there are little switches that open when the brake lever is pulled and kill the power) but that doesn't appear to be the case.
In case you're not familiar with the EV Warrior it runs 2 friction motors on the back wheel powered by 2 12 volt batteries in series. It uses a Curtis controller and the standard 24-volt scooter charger.
What's weird for me now is i 'm not getting intermittent anything - it just doesn't work. There's no power coming from the batteries at all. I've checked both batts with a multimeter and they're both putting out 12 volts. What's weirder is that when I connect the charger I DO get power - the front panel lights up and I can even spin the motor with the throttle (albeit, only 1.5a worth of spin). I'm now hoping there's some scooter genius out there that can tell me where my problem likely is. This thing cost me $400 and I love it - I don't want it to go kaput. Oh, and when I connect the charger the light stays green (it goes red while charging) until I open the throttle ( and there's actually a draw) then it goes red until I release the throttle.
Anybody? Any ideas?
