Hello I have a Gem E825 new trojan batteries . It just started coming up with fault code -15 . It will run fine you can drive it around stop and then press pedal to go and nothing code comes up -15 … why is it doing this ?
I also noticed that some times on charge one of the rear tail lights will glow a lilttle.
Any help would be great !!!
Thanks Carl
-15 is low battery…
It will do it after a full charge .
it will run fine , you can stop for ten minutes and the go to go and code will pop up.
leave it for a bit and it will be fine again .
Monitor the voltage at controller.
A bad connection will be warm after a hard run.
I suspect bad connection or bad ground somewhere as one of the tail lights glows very dull when it is on charge. Also. I noticed when lights are on one headlight is brighter than the other.
