90amp alternator, what wiring upgrades

[rustytoolss]

Replacing my old low amp alternator with a 90amp Denso. (I will be using an external REG, and a VOLT meter). So how much wiring needs to be upgraded? My thoughts are to leave MOST of the stock harness as is. But to add larger wiring to the systems that need it. But unsure what wiring needs attention.
So get me going in the right direction

There is absolutely NO WAY in hell that I would put a great big alternator like that on a stock system without bypassing the ammeter. Even Ma knew this wiring was marginal. There exists what is known as "fleet / taxi" wiring which was used on the 60 / 65 amp optional alternators. This is documented in the service manuals. These still used the ammeters, but Ma ran heavier gauge wiring through the bulkhead separately from the original bulkhead connector, which helped.

Before Al Gore invented internet, I damaged the bulkhead connector in my old 70 Road Runner back in the day, and drilled out the connector and ran heavier gauge wiring through the connector. This horrid faded old photo was taken about 73 or 74

hey check out a thread I started a while ago.

67dart273 gave me some great links and gave me some great info. There's a couple of other links to articles I found on moparmuscle.com

From guys I've been chatting with, if you do an upgrade to a 90 amp alt, your going to be pushing a lot of juice that could cook some of your electrical. I need to upgrade because I'm running fans from a contour, fuel pump, and I want a decent stereo.

Bill Evans made me a brand new harness that's set up to run my new FBO electronic ignition for $125. I figured that was a pretty cheep investment to prevent an engine fire. The harness doesn't include front headlights, but it looks great.

I did bypass the amp gauge.

I'd say you are "90a ready" LOL Just make sure you have a large enough wire from alternator to battery. No6 minimum, no 4 would not be too large.

I just was not sure if I would need to increase some of the wiring to things like Ign switch, headlight switch etc. thanks
