Ok so I replaced the alternator on my 1984 90 200tdi as the battery wasn't charging (new battery) and still not charging so traced all the wires using a wiring diagram I have 3 wires big brown wire, white wire and a yellow wire. I think the brown wire is wrong as its earthed and in my diagram it shows the brown wire linked up to the starter motor solenoid but when I do that I have no electrics and the truck won't turn over! What am I doing wrong?
