1985/1 Electrical Problems

Electrical

Vehicle Information: Model(924/944): 944; Year: 1985; Engine (type, size, modifications): 2.5L inline 4; Total Mileage: 139000;

Since pulling my car out of storage, I've been plagued with the following electrical Problems. 1. Cooling fan stays on when ignition is on2. Wiper voltage drops to 3 volts when I pull on the handle for washers.3. Speedometer stopped working (Economy light/cruise stopped at same time)I definitely have my work cut out for me. First step is figuring out proper disassembly and finding a proper wiring diagram. Here's my dilemma. Before I start, I want to have my facts straight. Both my Haynes Manual, and a Porsche Manual I have, indicate diagrams for 1984 model then 1985 and newer. Being that my 1985.1 is a dividing factor, what do I go by, the 1984 or 1985 diagrams. Also, what's the proper way to dismantle the dash assembly? Once again, I've only seen details on the 1985.2+ models.Thanks.
