Calling the electricians: I've got no power!

Not sure what buzz out means, but I'm pretty sure the earth is good and all checkable of course.

Mystery block is dead, like everything else... I'm surprised it's a mystery to you guys too (I wondered if it's a USA spec fitting or some such (e.g. a side stand or clutch cut-out switch, maybe?)). Question for DSS perhaps. Thinking about it, the mystery block is male and so I'd expect the power to be in the (missing) female part (as usual, eh guys?!!!!!... ladies, that's a compliment!).

Nothing has been powder-coated, but I take your point about anything getting in the way of a good connection.... nothing that a wire brushing can't sort out, eh?

If I can't sort this out soon, I'll seek local expert advice (which I guess rules you out Bitsa!).

Cheers all,

D.

Thanks again all,

I think you might have nailed it. Unfortunately, I won't be able to look again until next weekend. PM option much appreciated Frisky.

Cheers,

Hello again,

Having sourced a solenoid-to-loom cable from Steve at 400fourbits, I have today connected everything back up with mixed results:

1. When I switch on the ignition there are no warning lights.
2. The front pilot light, tail light and rear brake lights work.
3. The dip/main beam and indicators don't work.
4. The engine turns over on the starter motor and there are sparks at the plugs.

In the next few days I will have a look inside the headlight, etc. to see if I am missing some connections. There's definitely a few missing connections in the bulk grouping near the headstock under the tank. I assume that one or two of them will be for the horn that I haven't yet put back on the bike.

My only question for now: there is a green wire coming from the new DSS loom with a loop connector on the end. It emerges from the main loom behind the carbs and is about 8' long. I guess it's designed to go to earth (frame) but I'm reluctant to earth things if I'm unsure! Does anyone know what this wire should be connected to, please?

Thank you,

D.

p.s. Sorry I haven't attached a photo... (temporary, I hope) camera problem!

LesterPiglet:
Green is earth on our bikes. Having a ring on it confirms this. Some bikes had an earth on the rectifier, this seems positioned in the right place for that.

Bryanj:
Bolts on at a coil mount but make sure there is no paint/powdercoat where it connects or you can melt the loom, same goes for where the main earth goes to an engine mount/frame
