Been sitting on a new 105 amp GM alternator for years planning to replace the 45amp original on my 75 Manta. Your post may get me off the dime and get er done.

If you do, make sure that you replace your ammeter with a voltmeter.

I left my lights on one night and came out to a dead battery. Jump started it and drove off. A couple of minutes later smoke came out from under the dash. The Opel ammeter didn't like being overloaded by a 100 amp alternator.

Thanks for the reminder. I will re-read all the past posts on alternator upgrading before attempting it.

Well typically of some of my projects I'm just now getting around to doing this on two cars and realized the SI-10 105Amp I have is a one wire self exciter that I bought from Kent Darsey some time ago after he somehow ended up with two. (Wonder what he is doing these days. Haven't seen him around town either.)

Anyway I decided in the meantime to use this one wire SI-10 on my 1963 Thunderbird to upgrade it's original type 45 amp Ford alt.
So I bought a new CS130 105 amp one-wire self excited for the Manta which hopefully will get installed after RT66. Will just have to remember to goose the throttle on starting.
My manta doesn't have an ammeter (or voltmeter) so the overloaded ammeter isn't an issue.
Why is it that now that I'm retired projects take even longer to start and finish.

Don't want to turn this into a parts for sale thread but I decided not to use the new si10 105amp on my Thunderbird. It's plugged and wired and standard US shipping is free for $60. See Ad board.
End of my shameless plug.

If my chrome gm bracket ever fails I'll be digging out this thread. Nice work..
