Re: Cadillac alternator

[shirazcupala@xxxx]

I just did this 2 weeks ago. Works great.

I bought the alternator at NAPA ($150) because they have the 
superior Beck-Arnley remans instead of the cheapie Schucks ones. 
It was $50 more but I'd rather not run into trouble for relatively 
little money. They took my Motorola as a core with no questions.

To get it to work you have to get that J bracket. The only place I 
found one was at a larger Schucks store. I had to modify it 
slightly by drilling another hole lower down and sawing off the 
extra length. I also got the wiring harness adapter (also required) 
from Schucks too. Email me privately for part numbers.

Also check this instructions page which helped me a lot to 
understand and confirm the wiring config:

Note I did not need to do the pivot alternator bracket modification 
listed here.

100A works just fine in my car. My volt readings are roughly as 
follows:

850 RPM, 13v - all accessories off
850 RPM, 11.5v - headlights, cooling fans, blower on high, rear 
defrost on (I have no a/c)
1000+ RPM, 13.5v+ - no matter what is running

Checking voltage under load is key.

Please note that these readings are me just looking at the gauge. I 
was worried that this cheaper alternator (compared to the other ones 
mentioned on the DML or a BOSCH volvo replacement) was inferior 
because of the low output at low rpms. However, another PNDC club 
member and I were comparing volt gauge readings since he has a BOSCH 
105A reman alternator ($250+ unit)and we get about the same 
readings. The only nice thing about his is you can use the stock 
bracket and it's smaller in overall size. Be forewarned, the 
Cadillac one is HUGE, but does fit.

Note as part of this I cleaned the major rear grounds but have not 
cleaned the major front grounds. That made a huge, huge difference 
(I checked the gauge readings before and after). The next chance I 
get I will clean the front ones and possibly do the mod to add an 
additional heavy duty ground wire from the front grounds to the rear 
negative terminal / ground to really ensure good front ground. The 
volt gauge really dips on the headlights and fans which suggests to 
me that the ground up there is not as good in my car right now. 
I've read about this in several other posts here.
