Electrical problems

Post by tomsk » Wed May 23, 2007 8:28 pm

Can anyone help please? I have had the sludge light and charging light illuminate on tick over. They used to disappear when revving the engine.
They will now not go out at all.
At the same time that this happened, the fascia heater failed to blow out hot air. The blower part works, but only emitting luke warm or cold air?

With thanks

Guess it must be, as battery still ok, and bongo still running, thanking you Peter.

The light may refer to water in the fuel filter - drain it and see if it goes out.

The cool heater is either a broken cable to the flaps in the matrix or an airlock. You need to bleed the coolant system thoroughly and urgently in the event of any loss of heating. The coolant level may be low due to a leak - the heater going off is your last warning before bending a cylinder head. Thats worst case but worth checking in the circumstances.

check the fuse it`s the 3rd one in the underbonnet fuse housing (30 amp)

my sediment light and charging light came on one day a while ago
highbeam did`nt work either

changed the fuse all the lights went out and working fine since it seems they are all connected somehow thru that fuse
ECKY THUMP
