Re: CS alternator help and voltage issues..
I have had it with the CS-130 type alternators.
Yes they are small, light and mount pretty well in the 1st gen chassis, but all you have to do is look at them cross and they blow. Also, you just can't "take 'em apart and fix 'em" like a DN or SI alternator. I gave my installation 2 tries, one with an off the shelf alternator and the other with an Iceburg, both were shot inside of a week. Heaven forbid if I actually had a high amp load with a 5,000w sub-woofer or $60K stereo system with lambo doors, just factory AC and PW.
I wasn't interested in trying again so I bought a 78 amp (or there abouts) 12-SI and haven't thought about it again.
In my opinion, the CS-130 alts are fragile, even with the Iceburg upgrades, I wouldn't recommend them for reliable everyday use.
The only thing the CS-130 alternator was good for was; I didn't have to do any other modifications to install the 12-SI except for changing out the alternator pigtail. My ignition hot wire (#1 pigtail wire) was already modified with the resistor (factory guages) and the BATT connection was routed to the battery via a fused link, even reused the SENSE wire (#2 pigtail wire) to the horn relay BUSS bar.
12-SI, strong like bear, smart like tractor. Very heavy duty, no problems.
