Question about 1992 Cadillac DeVille
The large red wire (or wires) was connected to the bolt. the other small wires were connected to a plug that goes into a socket on the alternator. If you go to the dealership and ask for a repair plug you should be able to match the wire colors and solve your problem. Either that or go to the dealer and tell them you wish to look at an electrical service manual for your car.

sounds to me your on the right track. black ground, red hot, gray variable. your doing what i would do. if you can get to ware it plugs into motor unplug it and run 12 volts stright to it from your battery and see if it runs. as far as voltage i can't believe it would be more than 12 v to it. some thing you might want to chk. as long as your under the dash if its there is the resister, they chg.heater motor speeds. and if there bad motor may not run at all.

the purple wire is the only wire that should be on the smaller terminal of the starter.
The other wires all get mounted to the larger terminal of the starter.

OK, There should not be a "Tan" wire there. It is probably the "Red" or "Orange" wire that has faded real bad and just looks tan. It goes on the same post as the large black battery cable. It should be a 10 gauge wire. The other end of that wire goes to the "BAT" terminal on the alternator. (in case you want to check and make sure) The smaller black wires should be ground wires, They will attach to the transmission housing. Usually, there is a special bolt with a stud made on the end of it and a nut that secures the wires. As you said, the purple wire goes to the small post on the starter solenoid.

Hi, if the wire is connected by a nut on the back of the alternator it can go either to the battery or to the starter solenoid.

on the housing under the hood where your heater core and AC plumbing is there is a plug in rheostat that you need to remove and replace-take it off with the two screws that hold it and take it to a napa and they will sell you the replacement for about $20. Good Luck!

NOTE There is a trend among manufacturers today to refer to the source of belt-driven electrical power as a -generator-; however, by virtue of the method in which the -generator- produces electrical current the device is actually an -alternator-. The two terms may be used interchangeably.
