Just trolling for information and ideas on incorporating two electrical items into my car ie: stereo ( amp etc ) / electric fans ? Already have a plan just want to see what other thoughts are out there .
Check the amps for both the fans and stereo you want to use. You may want to also upgrade you alternator to a highter output to keep up with the load increase.Just trolling for information and ideas on incorporating two electrical items into my car ie: stereo ( amp etc ) / electric fans ?

Upgraded the alternator already to a 90 amp , will check the draw of those fans.Check the amps for both the fans and stereo you want to use. You may want to also upgrade you alternator to a highter output to keep up with the load increase.

Whats the inherent issue your referring to? I'm not to familiar with bulk head problem. Thats why I'm fishing for solutions to run a separate set of supply circuits for the add on fans etc , similar to Dano's idea above . Separate from running it through the factory box .BUT HAVE YOU fixed the inherent wiring issues? The ammeter / bulkhead connector issue/ circuit. The factory wiring does not have much headroom for heavier accessories CERTAINLY NOT 90AMP ALTERNATORS

Then run a BIG *** wire (with fuse) from alternator to battery
It depends on the alternator output and must be even larger if it's a "one wire." This is because the voltage sense for the VR is on the main (and only) charge wire. You'd have to find an appropriate recommendation, but for 90a I'd guess at least 6 and likely no4 on a "one wire"
just out of curiosity what size wire would you call a BIG *** wire? 10 or even 8 gauge? 65’s used, I believe, 12 gauge. According to the 82 J Bodies FSM, they still used 12 gauge from the alternator - my engine compartment wiring is loosely based on a combination of J and early A wiring
It depends on the length of the wire/cable and what the amp load is going to be. There are a multitude of charts available to help you determine the correct size you need. Just Google it. No guess work is needed. It's all been carefully researched.
Check a stereo store for the wire. They use under 10g wire for installs.I'd use either no8 or a pair of no10 because they are likely easier to come up with. Voltage drop in the charge wire with a conventional "non 1 wire" is not quite as important, because the sense regulates at the battery.
Even this you must be careful of. Some charts (for automotive/ 12V) are erroneously based on AC house power charts which typically allow more voltage drop. And as I've said before IF you are using a "one wire" setup you may be well advised to step up one size even on a "good" chart. A "one wire" MUST have very little voltage drop on the charge wire. And if you are anywhere near the "step" in the chart amperage wise, you need to step up a size as well.It depends on the length of the wire/cable and what the amp load is going to be.

Make sure it's copper core a lot of stereo wire isn't .Check a stereo store for the wire.
