Flashing red light

[chalky BV]

Sat in my 92 griff and started it up and noticed that the ignition light was randomly flashing but very faintly had the alternator serviced all ok and the amp meter is fine but today when I started it up I noticed that the interior light was flashing in time with the ignition light rev up engine and it's still there but if I turn on the side light it stops any one had a similar problem

You can maybe start by checking how is the big 100A fuse on the chassis. If it is cracked this can make the ignition light glow a bit or flashing.

Hi thanks for your replys I can not find a big fuse on my car also have have cleaned all the terminals on the alternator but will have a another look thrcar is running fine and the battery is well charged

Early Griffs didn’t have the 100A fuse. Mines May 92 and no fuse.
Apparently these weren’t fitted until 95/96.

Maybe have a look at the engine grounds.

Indeed early ones do not have this fuse.
This is weird if the light is on and the alternator is fine. Check the signal from the alternator as DRV V8 mentioned. But why would it affect the interior light?
Else have you checked how healthy is the battery?

On some cars it isn't.
I don't believe many production cars have one.
No excuse I know but it was added to protect in the event of alternator shorts.

Hi I took the body off some years ago to do the outriggers and made sore of a good earth on all earthing parts (there are quite a few )will get battery checked at weekend I think I have a short some wear like when you have a bad earth on a rear light and the brake light comes on faintly with the flashers going to keep looking thanks guys once again
