Don't know yet. It won't be on the road for a few weeks still. A friend has the km2 and they're surprisingly quiet. Hoping as these are a copy. They'll be similar. Maybe???
chris off of here has been doing it recently, ill see if i can give him a prod, looks pretty straight forward but theres a few bit you may not think about
I'm with GG on this. Fitting a switch as has been done is a tried and tested method of ruling out a huge part of the circuit. It's not high tech but it works. So if it starts fine from said switch the problem is before said switch! It's not complicated.
