67 Barracuda Heavy Electric Load
I had a High Output alternator on my car once, discharged at idle, like maybe good for a drag car, seemed totally useless to me. I believe it was a Power Master totally useless part. I bought a round back alternator from Autozone or somewhere been good for 15 years now.
I run ground wire from voltage regulator to the coil bracket bolt on intake manifold. Make sure a ground wire runs from back of head to firewall too. When I used to run mopar electronic ignition I also ground that to engine
I did notice if I unplug bulkhead then plug it back together I have to go under dash and push in and seat one of those fat amp wires cause they get pushed in a tad creating a loose connection. Check verify dont assume.
I still have stock wiring no issues yet. But the improved wiring mods sound like in my future.
Clutch fan with shroud works fine for me. No way I would run electric fans without all the wiring mods, volt meter, headlight relays etc.
I recently had some bozo with a ratty old chevy truck at car show tell me 'you need electric fans your loosing power'? Yeah sure I can make you invisible with a cloud of tire smoke with my loosing power car ok.
