Hi all,

I've recently bought a diy kit and fitted it. All was well for two weeks and then I jumped off a kerb and the electrics cut out.
The kit is a 48v 1500w 15ah
The electrics cut out when using the throttle or pas system (wheel moves barely an inch) and the display/power trips out.
I've metered the battery and it's showing 53.8volts
And is fully charged.

If I connect the charger to the battery and use the throttle and or pas system the bike runs perfectly (unable to test under a load ie; sat on it for obvious reasons)

All connections seem fine the thing that is doing my head in is the fact it works when connected to mains.

At a not of a loss, any help would be greatly appreciated.

Regards

Rick
