Alternator DL7157

[philip l. stewart]

GMCnetters,
Using the recommendations from this excellent group, I installed the
Autozone Dura Last DL7157 alternator listed for a 1979 Cadillac
Eldorado. It's described to be a 100 amp unit and was an exact
replacement fit. It runs much quieter than the old one which was making
worn bearing noises. As J.R. Wright suggested, I also upgraded the
power wire from the alternator to the battery isolator device by
installing an 8 ga. wire.

A pleasant surprise to me was that the "generator" warning light now
goes out completely once the engine starts instead of dimly glowing all
the time. I've read here before that the dim light is quirk of the GMC
which one has to get use to or do a diode modification of some sort to
get it to stay off. In my case, at least, the rebuilt DL7157 took care
of that problem also.

As Arch would say, that's what I did.

Phil, glad that is working out. Mine 7157 seems ok
too. Guess time will tell the story.

BTW where did you get the #8 wire? What I have seen
in the hardware store is stiff and hard to work with.
I was in Chattanooga visiting daughter for
Thanksgiving.

Bill,
I had about 10 feet of the #8 wire in my "scrap supplies" and where I
originally got it? ---well its been too long to remember. I would
suggest going to the West Marine catalog or web site to find some
though. They have a large stock of most electrical parts and supplies.
The larger gauge wire can usually be ordered by the foot, I believe.
HTH. and good luck.

Bill,
Radio Shack has some VERY nice stuff. Black of Red, not cheep @ $1 per foot
but very flexible with very small copper stands and well insulated. I used
it on my DC/AC inverter. Good stuff.
