Hi,

After the winter break, I went to check the battery on my bike (it was about 75% a month or so ago) but the system won't power.

I thought it may be a flat battery so charged it but still no joy. The main connections are clean & shiny so I was wondering if anyone can shed any light or suggest some fault finding techniques.

Thx!

Check the brake cut outs, mine wouldn't start the other day after I had been playing with the brakes, took me ages to connect the two things ...

check the battery output.
After along period of rest, the battery may be out of balance.

All sorted. I measured the battery outout at the bullet connectors & it was 3Vdc :confused:

Took the battery off & it was 40Vdc, put it back on the bike & the voltage at the bullet connectors was 40Vdc & the controller powers fine :)
