Hi all, i have a question about a defender 90 (1989) with a 200tdi from a discovery (turbo low down) i have had alot of wiring issues so far :doh:

i have put a new alternator on and i have 13v~14v going to the battery/starter motor when running and on the wire going to the batt light on dash 25v~32v..... 25v while ticking over, and once revved rises to around 32v and getting the battery light very dim with diff lock light is on then after revving hard heard a pop and the diff lock light and battery light now stopped working????

ANY ideas please really stuggling with this one now

you would get a pop if you really have 25-32 volts going to dash as it only has 12v bulbs

sounds like you have the battery light wire on the wrong terminal on the alternator, it sounds like its on the "w" conector witch is for the rev counter in a disco.

does your wiring have the resistor and diode connected in circuit with the ign warning light

Click to expand...

there is only three terminals on the alternator so heres how i have done it.

No.1 - Going to battery/starter motor (13v~14v)
No.2 - Going to dash light (24v~30v) No resistir or diode, just a straight wire to dash light.
No.3 - Terminal has rubber grommet over it and has something like 100v
