alternator back feed
Mikef - 16/2/21 at 01:06 PM

I have just changed to a digital dash, and all the warning lights are working etc. When I turn the ignition off the engine keeps running. I have tracked this to the Alternator warning light feed. Voltages are correct 0v when ign on / warning light on and 13.5 v /light off with engine on tickover. I have seen some info online about this and one of the fixes is to put a diode in line before the warning light, however some articles say that this could cause damage to the alternator. It was working fine before I changed over to digital dash, and I have changed no other electrical items or wiring.

does the digidash use an led rather then a conventional bulb?

as above ^^^^, try changing the bulb for a normal one or putting a normal bulb in line with the LED, that should sort it oot
