Guys - I have maxed out my electrical brainpower and can't find an answer specific to my '75. Can a kind sole out there please give me the answer?
Red power wire is switched, yellow needs to stay hot. Thanks in advance.... |

The Gang of Four supplies power to the entire car, EXCEPT the starter and alternator:
- Ignition switch, circuit 30 - S11 as described above - S13 fuse (on relay plate), power to heater J14 blower relay - J16 power supply relay I'd suggest installing a resettable circuit breaker in a convenient place bisecting the wire from the battery to the Gang; 100A oughtta be enough to protect that circuit (4xAWG6 is roughly 200A total but I simply cannot imagine the whole normally-equipped car - minus starter and generator - draws more than 100A). I've not seen a stock car - my two cars were already altered and batteries re-located - so I can't suggest where that location might be...I installed fuses/breakers in both. https://www.amazon.com/gp/product/B06Y4ZQ5SC That still leaves the big B-lead between battery and starter and alternator unfused, so, well, keep your fingers crossed. |
