Fuse Value & ID
I have a 1976 911S. I over-revved the PermaTune unit and blew it out. I began the MSD-6AL swap out, only to find the relay strip (S22, S23, S24) was up-side-down. Then, I'm guessing they didn't have a multi-meter, because they added an external jumper even tho there is a jumper on the under side of the fuse block. I'm working on reading the Current Flow Diagrams from a Chilton's, to determine which wires terminate where. Does anyone have a fuse number list that indicates the amperage value and maybe grouping by fuse block and location. I have the values that were in positions; S22, S23, & S24, but I don't trust them. All but one wire, the "Yellow on Blue" wire has cooked the insulation, so I'd like a little help, please?

Does anyone know where to find information regarding; Fuses, Fuse Blocks, and Amperage for each Fuse Number? There must be a tables somewhere that lists this information for each year and by available options. I'm making progress identifying the info for my '76 911S. I will share it when I've completed the table.

Fuse info
I will look in my Porsche manual later today and see if I have a '76 wiring schematic. If so, I may be able to copy and send to you.

fuse amperage should be in the owner's manual if you have one. not sure what you mean by overreving the permatune. i don't think that is possible.

Fuse values, etc.
This is what I found in my Porsche factory shop manual for the 1976 model year.
Fuse #21 (top) Red fuse, 16Amps, Red wire leaving fuse to the Fuel Pump Relay Fuse #22 (middle) Yellow fuse (5Amps), Green/Yellow (goes to 14 pin connector) and Red/Black wires leaving fuse going to the Heater Blower Relay (relay trip wire) Fuse #23 (bottom) Blue Fuse, 25 amps, goes to the heater blower relay (main power wire). I hope this helps!

Thank, everyone for the info. I really appreciate it. Yes, I'm fairly certain that the fuses are S22,S23,& S24. I'm still working on it, and I believe that S24 is for the rear window defogger.

"Over-revving" the PermaTune unit is, I believe technically accurate. The CD Unit, whether Bosche or PermaTune, is the Capacitive Discharge Unit that is fired from the distributor points. So, either it was just the end of it's life cycle or I tried to make it discharge too rapidly.
The first time that I Lifted the distributor cap, I noticed more stuff in there than a rotor, points, and a condenser. As I began looking at it closely, I noticed a centripetal switch. I figured that it was a mechanical Rev-Limiting switch. Guess I need to look at it closer, because it obviously didn't work. |
