Thanks guys!! I've taken it all out and am going back with reproduction OEM harnesses from Year One and will be done with it. She has the factory fusible link but like you said, it was completely bypassed and wasn't worth a crap in this scenario. If it didn't' fry so much of my wiring I'd just do the MAD upgrade as this sounds like the way to go. Unfortunately in this case ALL the wiring was damaged in a way that it all just needs to be replaced.

You need to do the Mad upgrade no matter what....if this is a car you plan on driving. The bulkhead is always going to be an issue

I'm with you on that. I was thinking last night about just going forward and doing this mod. I like the idea of NOT sending the juice through the bulkhead!

It is not hard to run a heavier wire through the bulk head. just drill out the original location and run a longer wire through following the original routing. It eliminates the troubles some bulkhead connection and is not really noticeable.

.make sure the original alt output wire in the harness is disconnected from the alt.




Is there ANYTHING else that needs to be disconnected to do this mod? Under dash, at start relay, etc... I am running a stock replacement alternator (65 amp) that is the externally regulated 3 wire. Thanks for your help!!

It's Nacho's parallel bypass. I bought a bunch of spools of stranded wire of different gauges/different colors of insulation then set the harness (65 dart) on the floor & made a new harness next to it starting from scratch one wire at a time. I'd add/solder in 1 wire/circuit then take that wire out of the old harness till the new one took shape & the old one dissappeared 1 wire at a time. NAPA brass terminals 725145 female 725147 male. this gave me the same shape on the harness routing & would for sure be cheaper than a Y1 item. Also I went 1 gauge larger (smaller #) on most of the wires (some dont need to be larger). Take pics & LABEL where each wire goes. Just me I like the ammeter & yes all connections need to be cleaned/checked & I relay all addons to the alt side rather than to the batt & I strive to keep the ammeter needle close to 12 o'clock. This is what works for me

Check the inner nuts(both sides on both studs) on the amp gauge, they can come loose on the studs causing a open circiut, which will make the votage regulator think the battery needs all the amps the alernator can make
