Hi,
I have purchased a new alternator (from ebay) for my 1993 D254 4.3 Turbo Diesel. The wiring diagram in the manual shows where the colored wires go on the original but give no information about where they should go on the new one.
On the wiring harness from the engine i have:
Red (Alternator Output)
Black (Alternator Negative)
Grey (Tach)
Brown ??
The brown goes back to the starter relay circuit.
I have tried attaching the brown to the purple on the alternator but it won't make the relay kick in. If I connect a wire from the brown on the starter relay straight to the battery negative, the engine kicks over no problems.
Does anyone knows how I should connect this up?
Many thanks in advance
Andy
