Looking for a suggestion on which alternator to install on my 350, be it an 80, 100, or 140 amp. Any suggestion will be greatly appreciated. Thanks. Ted
So only if the battery is very low will that much current ever go through in a 55 or 56. I didn't think about that because my 57 goes to the battery.since the charge wire runs inside the car before it goes back through the firewall to the battery, in the event of a almost dead battery.
Not a problem as long as the wiring is up to the task. :tuToo late. I just purchased the following alternator from Summit's. I will be installing an after market wiring system, and not have any thing close to the original wiring. Thanks for all of the input. Ted
After reading these responses I became concerned and contacted Summit via email to see if I can change my order from the 140 amp to the 100 amp alternator. I hope the 100 will be more than enough. Thanks. TedNot a problem as long as the wiring is up to the task. :tu
does that still work? I've heard lots of bad things about anything from Chinese DB Electrical. Their prices are way lower for a reason :anim_25:Here's one I bought.
the aftermarket wiring kit that you bought... is it a stock replacement or will it run from the alt to the battery? did you every say what your car was?After reading these responses I became concerned and contacted Summit via email to see if I can change my order from the 140 amp to the 100 amp alternator. I hope the 100 will be more than enough. Thanks. Ted
Makes sense. I filed this info, Thanks Mike.I do a lot of ignition system conversion work, and recommend alternators for those conversions. That said, I have over 600 old, wrecking yard 12SI alternators running around on all sorts of different makes/models of automobiles, boats, fork lifts, name it.
ALL of those alternators came off Chevy Citation and their clones, all 12SI, 94 ampere, converted with just one jumper wire on the outside of the alternator, to "single wire" use, with only one failure, a diode went on one of my own units.
All of these were wrecking yard units, literally taken apart, cleaned, reassembled, installed, and run. About 10 percent of them required a simple, low cost rebuild kit, the rest, just cleaned up and run.
I do not, for any reason, run the CS series GM alternators, too much failure, problems, they just tear themselves apart. The factory CS alternator, and ALL subsequent replacements, on my 1986 GMC Safari van, died gruesome deaths. I finally got so irritated at those CS alt failures, I retrofitted a 12SI 94 amp Citation alt, some 12 years ago, NO problems since then. Sure is better than a CS alternator failing every 6 months or so.
It is also nicer to pay only 15 bucks at a wrecking yard, and use a little effort to redo an SI alt, ONE TIME, vs 100 bucks EVERY 6 months for a useless, failure imminent CS alt replacement.
Just my 40 plus years of hands on experiences.
