Washer Light Case

<< < (2/4) > >>

K2-K6:
Aren't there various rubber mounts that would make the earth route at least patchy on the fork ear ? Hence the need to have a competent earth strap to indicators.

Alexrayz:
I had that issue a few months back when I was redoing my wiring. The green wires on these nuts are there to improve the grounding of the mounting bracket.
With the plastic shell, the paint and the rubber mounts, it is not the most conductive area. Had me scratching my head for a while as whenever the headlight lens and metal ring touched the front mudguard the lights would improve by 50% if not more compared to when it was on the bucket.
Turns out it was just the ground that was shite in that area.

SeanFD:
Thanks for the thoughts guys. I had considered some of those. But ...

Looking at the wiring diagram I have:

There are 8 earth connections all coming from the main loom as shown in the pic, so the headlight bucket, being plastic as noted, doesn't come into it.

Unlike on the 750, the things that screw into these "washers light case" are just reflectors; the indicators are mounted on arms from the headlight mounting bracket, or stay as Honda calls it. Now although this is rubber mounted, I am still getting an earth connection on the indicator mounting bolts, which is why I thought the earthing nuts were, perhaps, superfluous.

The indicators were not working properly last night, so I'm going to go with Alexrayz's suggestion that the bracket is not well earthed. Off out now to test the hypothesis; I'll let you know.

Alexrayz:
It does connect to the side reflectors but it also connects with the headlight mounting bracket. I guess this is where you're supposed to get your connection to the metal body of the bike. Crud can get in there and make it less conductive.
Best thing to do is to use a multimeter in continuity mode, attach the black probe to the negative terminal of the battery and then use the over probe ti check for continuity. Where it doesn't beep is where you have bad grounding.

SeanFD:
I connected the two wires, and ..... everything worked!  ;DExcept one front indicator. :(

I decided to check the bulb and (this took a little while as I got distracted). The bulb was OK. I switched the two front bulbs anyway, and ... nothing worked!!  :-[

Well not quite nothing; when I indicated left, the right instrument panel light worked, and when I indicated right, the rear left indicator worked.

I spent ages checking everything, and then noticed that the voltage at one point was only 8,5V. The battery I was using is on old one with a bit of history, though it does seem to hold a charge when not stressed.

I'm not sure why a low voltage would cause the strange happenings, but I put it on charge and moved on to other things. I will ry again tomorrow.

Oh, I did find out that the wiring and feed to the coils is OK; with the kill switch on "Run" the coils got quite warm. Which may explain my flat battery!!

Ah well.
