Earthing help! + types of leads

[elford_tim]

also - when i checked the voltage on the battery it was 11.9 then with any electrics on it dropped to approx 11.4?

im sure this used to be 12.4?

I think you\'ve either got something slowly draining your battery or your battery isn\'t exactly fighting fit anymore. 12.4V ain\'t that great on a battery but I\'d consider that acceptable, below 12V and it definitely isn\'t.

As grinder said, your rear brake light problem is very likely to be a bad earth at the lights; dig your way through the plastic to the cluster and trace the earth lead there...

had the battery load tested + ok + alternator is fine!

please someone guide me

First test - run the engine, check the voltage across the battery terminals - with the engine idleing, it should be at least 13.2V, if not more...

last time i looked it was 14.4-14.6?

done lots of sanding and vaselining to loads of terminals and earths? issue remains?

OK, voltage at the battery sounds good & healthy then.
