Glowing Alternator Light
Posted 04 August 2011 - 02:54 PM
Any ideas what might cause this and where I should look before I strip all the electrics down again to find out?
NB: New alternater fitted in the last 6 months and new battery fitted in the last 12 months

Or a wiring fault, short in the ignition light circuit.
Talk less, listen more.

Glow stays the same no matter what the revs.
Will get the multi out in a while and test the voltage.

So to me this mean the alt is working and its probably something else causing the bulb to glow very slightly? Just no idea what.

1) a short/ water ingress
2) the alternater is not fully switching to live output.

Only noticed a faint glow at night and seemed to get a bit brighter if you put more load on (ie as well as the headlights, which were on anyway, turned on the heater fan and it got brighter).
Turned out that the three connections onto the back of the alternator were a bit lose. Squeezed them all up a bit to make them connect better and the dim light went away.

Remember what happened to me last Oct....?
I had been getting the dreaded glowing light (only visible at night). Eventually Altenator totally packed in. Knackered brush's and voltage regulator on mine...
Might also be worth checking belt ain't slipping
