240 alternator exciter wire 200

Inga is an 86 245DL and her four grey harness wires were in really bad shape. The starter solenoid wire was bare for at least five inches when she moved to my house. Still started right up but it was a matter of time there. Then got the dread warning lights coming on and it was time to replace wires. If the oil pressure and exciter wire are bad the starter wire and water temp wire are in at least as bad a shape.

Inexpensive solution is to go to an auto parts house and purchase a trailer harness (Both sides). Cost me less than $6 and the wires are TFE (Teflon). That makes the insulation good to over 800F so not problem using them under the hood.

One more suggestion ,(unless you just want to get greasy) is to run the oil pressure and exciter wire down the firewall and passengers fender to reach the pressure switch and exciter wire. The connector on the oil pressure switch is almost impossible to find without slicing one off a donor harness so you want to try and save the one on your car.

While you are in there around the alternator, check out the blue ground wire that goes from the Alt frame to the engine block also. That wire gets eaten up over time and you need a good solid ground to the frame of the alternator to have a good charging system.

Had the connector installed for going on three years and 50K miles now and still working like a champ.

Regards,

Paul
