It is funny to see this topic, I am seeing the same thing in my 96. I have yet do do anything cause I have never really had a problem..just the dimming of the lights when applying the brakes at night. I should however fix it before it does cause a problem.

According to my RPO codes: K68 - generator 105 amp

Too weak? Or is this how I have to drive?
Best advice? Either rebuild it yourself (If you feel you're up to it) OR Get it rebuilt by a shop. Either way get it upgraded (rewound) for a higher amperage to handle your needs. I rebuild my own. Last one cost me $80.00 Cdn in parts.

The battery cables are not a bad suggestion, but, the battery is ONLY used to start the vehicle. After the initial start, the battery no longer is part of the equation. A bad ground will cause all sorts of problems to a very intensive electrical car like our Bonnevilles.

Yes and actually the ground is the biggest issue. The sparking even at small amounts will stress the unit quite a bit. Regardless of your ALT choice it also pays to have a spare. If you do rebuild it yourself donít go to a regular shop. Do your homework and buy the proper parts. Gm replacements are not up to heavy use. They are intended for a properly working car.

The rear bearing is the main issue not only for its life expectancy but also its heat transfer and the ability to deal with the heat transferred.

The units I offer are more of a courtesy than a moneymaker but they are backed by a reasonable warranty and I have had no major problems.

Since a few months the generator of my Bonneville '95 refuses to load properly when I stop the car
-temp 90 F
-gear in D
-break on
-(running day)lights on
-AC on
No problems when temp is lower. No problems when I keep driving.
Replacing voltage regulator didn't solve anything at all. I did read the posting of speedyguy: could the rear bearing be the cause of this problem? If true, is there a solution?

Not 100% true. A bad battery will suck the life out of your car, but it'd have to be bad enough to barely start the car. Doesn't sound like an issue in this case.
