Black Bomber not charging
royhall:
This is the wiring diagram I modified at the time. Does it look correct? It has added, a voltage regulator from a later model, and a Silicone rectifier in place of the Selenium unit.

That's weird Roy only one coil and contact breaker?
This is a decent 5-speed diagram .... of course in the Bomber loom the brown wire changed to pink and the pink changed to white
Basically on the 5-sp later codes the Yellow and pink outputs are wired directly to the single phase silicon rectifier. The white wire is the night charging coil and goes through the headlamp switch and connects to the rectifier when the lights are switched on to boost the power (the switch connects together the white and yellow wires with light on) . The yellow wire also connects the the solid state regulator as a sense wire. The other two wires of the regulator connect to the battery positive (black via ignition switch) and negative (green) .. as drawn in your diagram.

Thanks for that Ash. I have seen that wiring diagram before, unfortunately it does not represent the wiring that's actually on an early Bomber. As a for instance the lights are controlled by the ignition switch and not seperate switches, plus the pink from the generator does not go straight to the rectifier but via the ignition switch to cut in with the lights. Although my diagram only shows the one coil (I didn't bother changing that bit as it's obvious) it is actually what was on my bike originally except for the minor voltage regulator and rectifier changes. I will at some point change it to show two coils and points then it should be correct. Do the regulator/rectifier changes I made look correct to you.

No because the PINK on the late alternator should connect directly to the rectifier AC input ..this was the BROWN wire originally on the K0 so it should connect to the BROWN loom wire (not via the switch). The YELLOW wire is the same for both models and that should connect directly to the other AC terminal of the rectifier (it also goes to the switch and to the regulator you added) . The WHITE wire of the the late alternator was PINK on the K0 so the WHITE wire of the late alternator should connect to the K0 loom PINK wire. Hope this all makes sense :)

That makes sense Ash. This is the headache for this weekend. There's a possible extra mix up as the harness is also new so could be either wire colours will have to recheck. It's a really good quality harness that came from Vietnam, not too expensive either. Is there another way to check which wires are which from the alternator as the colours are very faded and hard to really be sure about. The pink has faded virtually white and the white is stained darker, I think? Once I get this all right I will update my wiring diagram to correctly show what is actually there.
