964 wiring diagrams

Hello- I have been using some of this cold weather down time to chase down some of the battery draining gremlins in my car. This lead me to the factory wiring diagrams. Is there a user friendly manual for these diagrams anywhere? Thanks

Hi,
Thought my problem was something draining the battery. Turns out it was the battery. One almost dead cell. Drove me nuts for weeks until my other cars battery died. When I took it into Interstate, I learned a lot about batteries and how to use a hydrometer. I'd been using a voltage meter before. Volts in the Porsche's battery after a week in the garage would run down to 10.48 or lower. My little maintenance charger could get it back to around 12.2 V and the car would start, but after a few more days in the garage it would need to be charged again. That one cell was just weak enough to trick me into thinking there was a battery drain. The battery just wasn't coming close enough to the 550 cold cranking amp rating.
