Electrickery question

So I'm in the middle of rewiring the front of Rat Rod, headlights, indicators, horn, fan, air horn inclusive of fitting relays. Now all seemed to be going well, I was testing the new wiring and....... The indicators have stopped working. When I first tried the voltage stabalizer clicked like a flasher unit now it doesn't, only 6 volts at the flasher unit. The battery is fully charged. I've barely touched the indicator wiring and I haven't touched the rear indicator wiring at all. Any ideas????

6 volts with respect to battery negative, or a piece of metalwork? What voltage do you have on the ignition supply fuse in the fusebox (both sides of the fuse)?

Phil I used the earthing point behind the dash. I've popped out, so I'll have to check the fuse when I get back.

Not "that" earthing point?...

Phil It has an extra, heavy duty earth cable from 'that' earthing point direct to the chassis. I've been adding earths all over the car, some of my earths have earths.

Fixed it self. Battery charger has been on since I went out and I'm assuming low battery because it all works as it should and I now get 12 volts at the flasher unit. My battery charger had a light on saying charged and maintaining which is why I assumed it was charged.

Phil the resistance between "that" earth and the battery is 0.5 Omps, are you happy with that :D

He probably would be if any of us knew what that meant. :mrgreen:

So 8/9 years ago Rat Rod suffered complete electrickery failure at curbs. Phil and Jim traced it to a combination of a horrifically wired hazard switch and the earthing point behind the dash on a 5 (dead centre). I'm assuming when Phil says "that" earth, that's what he means.

Yep - the BDR earth lashed in temporarily during a monsoon at Curborough.

0.5 OHMS is actually quite high but that’s probably the resistance of the leads on your meter ;)
