Black Bomber not charging

<< < (8/8)

Thanks Ash. I would appear to be back to front, ie much higher amperage with the lights on. I would have thought it would be the other way around.
I think I may just ride it with the lights on all the time, I get at least a 4 amp charge that way.

Yes it is confusing ... but as long as you have a decent positive charge once the engine is  running at all engine speeds you should be OK. It's really the ability of the charging system to replenish the battery charge lost, after cranking the engine with the electric start /ignition coil current,  which is critical (provided that the running charge is positive).

It's a bit rough and ready (I will try and improve it when I have time) but this is now the wiring diagram that reflects what is actually on my 1967 Black Bomber. Fitted is a new harness with original Bomber wire colours, an alternator and rotor from a later K4 model, a voltage regulator from a later model and an AGM battery. It is all fitted and working correctly. Hope this is a help to anyone that has been watching this thread.
