I have a 2004 sixty-5 and am having some electrical gremlins. Occasionally, when I have the bike at idle with both the indicators and brake lights on, the lights will momentarily die and the engine will stop. Also, the lights will occasionally not turn on when the key is put in until after the engine turns over several times from the kick starter. I've replaced the battery and have it hooked up to a trickle charger which seems to have helped a bit but the problem persists. Also worth noting that I have the boyer power box, am making about 12.7v at the battery while revving the engine, and am making about 15v ac of the stator.

15 volts A/C is too low and so is 12.7 D/C at the battery, that is the standing battery voltage

When you say the lights will not turn on unless the engine is turned over, do you mean the head and tail ligjts? If so that is because they are AC, run directly from the alternator, and only work with the engine running.

I agree Norm, anything much over tick over even with the lights on, it should be 14-15 volts at the battery.

As said already too low at alternator should be around 30v see technical notes on left of board for details on charging Bullet A/C -D/C for after 1999 onwards and it will help explain how to test and check it out. http://hitchcocks.sincordia.co.uk/pictu ... 999_on.pdf

Solution to this turned out to be that the lead coming from the battery was striped and shorting against the frame, this was compounded by the fact that the aftermarket alternator instaled by the previous owner wasn't properly centered. Thank's for the help.
