Hot start probs - a cure?

Found the following here; I have a 1991 VW Cabriolet. When I drive my car for about... - Q&A


For all you folks having a hot-start problem on VW'sfrom mid 1980's to early 1990's, here you go! This solution will cost you about $20 and you should never have the problem again.

This problem typically only arises on cars with Automatic trans.

Basically, the idea is to have voltage going direct to the starter motor solenoid through a switch wired direct from the battery.

A Ford Solenoid Switch (#SS581) can be used, and bought for less than $20. It has two terminals on top, and a terminal on each side. It should have a little attachment plate with a hole in it that attaches to the right hand back valve cover stud with a nut.

Trace the wires from the starter motor solenoid to the ignition. There are two of them and may be partially wrapped in a loom. One is black in color. The other is black and red and larger in thickness. The black wire should be left as it is. The black and red wire should be cut just above the valve cover, where it bolts down. On mine, it is about 4 inches from a connector on the ignition side. Crimp a round connector onto the end of the black and red wire from the starter solenoid to fit over the terminal on the right side (back) of the switch. Tighten it down with a washer and nut.

The upper piece of the red and black wire needs a round connector crimped on it, and is attached to the left (front) of the two terminals on top of the Ford Solenoid switch, and tightened down with a washer and nut. The terminal next to it is not used.
Cut a 24 inch length of wire, the same thickness as the black and red wire. Crimp a round connector onto both ends. The one end attaches to the positive terminal of the battery, and the other end attaches to the left side (front) of the Ford Solenoid switch. Hope I haven?t missed anything. Start the car.
