Washer Light Case

(1/4) > >>

SeanFD:
I've been working on the wiring of my little Rusty and have just got into the headlight bucket.

The parts fiche shows an item called "washer headlight case" used as a nut to hold the headlight in place (No 466 on the diagram)

This had an earth wire attached (for the indicators as on the CB750K, I'm assuming) but I cannot see the reason for this as the indicators must be earthed on the mounting bracket – at least mine are.

Can anyone confirm this, which means the wiring is un-necessary?

If so also confirm the thread on the mounting bolts; I think it is M10x1.25?

Probably used because its a standard part used on most Hondas, not sure of thread

I thought the earth was for the headlamp unit not just the indicators.

If my memory serves me correctly, all the green earth wires from all the other fittings in the shell finish up in a multi connector, and this could be the main earth lead return as the shell is plastic. If I'm wrong, sorry. Blame Anno Domini, a good meal, and alcohol.  Regards, Mike.

I'm pretty sure you're right. The headlight and indicator bracket is rubber mounted so not a good earth, hence the earth wires.
