[Roadsters] Mitty Bad News

[Hall, Phillip B. (MSFC-ED03)]

 Good points John.  My '66 has the one-wire GM alt and like it.  It
takes charging issues out of the equation, but as you said - there are
draw-backs.

On the 67 2000, the wiring is in very good condition and has a new
regulator.  I will have the system tested and put it back stock.  I
don't have plans for 12" woofers or even driving lights.

The alternator on the car is made by Mitsubishi.  Is that stock????  I
don't remember them being manufactured by Mitu.  The other alts I have I
think are built by Hitachi.  Hope to get it all sorted out Friday.

Phil

REgarding a dead alternator, the question arose:
> Now - repair original or one-wire... That is the question....

Is you car taxing the original alternator (added lights, big stereo,
whatever)? Do you have other problems (bad wiring, flaky regulator)? If
you have a stock setup, with good wiring and no special needs, then a
set of brushes in the existing alternator and you're likely ready to go.
A one-wire means easier to get a replacement on the road, it bypasses
bad wiring, it gives more power BUT requires bypassing the ammeter so
now you don't know when that new alt goes south :-)

Yes, yes, there's ways around that. Use a shunt and have the ammeter
pass part of the load. Or use a two-wire and add the idiot light
circuit. But doing it right requires wiring changes. Doing it wrong
risks burning down the car.
