Electrical gremlin in dash

[Oldiebut goodie]

If there are no odd noises you have started up someone else's vehicle by mistake!

[t3wullie]

Yep...... my 1971 Series 2a Land Rover ........... diesel

[CovKid]

Its not a tired battery is it?

[t3wullie]

Battery's fine.
It's not when all the electric things are switched on it's when any one or more of of these come on

sidelights; headlights; indicators; hazard warning lights; brakelights; heater fan; screen wash; wipers.

but not when the glow plugs are on (wired separately, not through the main loom).
I've now received a pack of LM 7812 voltage regulators which I will try out this evening if the rain stops!

[t3wullie]

Ah well, more money down the drain.
On the bright side it was only 2 quid for 5 voltage regulators. I can always sell them on ebay.
.......... still no joy with the gauge.
