Any ideas what would be a good way to upgrade this old system? Not having any problems but I don't think it is a very strong charging system in these old cars. Even when I hit the brakes I can hear the fuel pump change pitch dramatically and, I won't even get into the turn signal effect on the fuel pump

Don.



Just thinking there must be an easy upgrade......or is it that simple??

I had the same problem with my challenger.

I got a later model high amp out of a pick-up late 70"s i think.

I brought a reman version using the late truck appication. found a 80 amp and installed i also installed a volt meter.

At idle i found that iwas dropping to around 12.8-13.2 volts.

My idle speed was aroudn 700-750 rpms

Well my alternator went bad and i went to a local rebulder was charged $125 for the rebuild ever since at idle i now charge at 14.-14.5 at the same idle speed.

i have an aftermarket cd deck installed along with digital guages, even at night with my headlights on my voltage doesn't drop.

I befroe the rebuild at stops at night i could see the lights dim i step on the break he volts would go lower and lower.

i think the problem lies in old worn parts and carppy rebuilds cheap units sold at the local parts store.
