OOPS, You do have a point (V-belts). This is my first V-belt since using them in the 1980's... DOH!

OK Guys,
WOW! Much appreciative of all the suggestion for trying to resolve this issue. I think while I've got the thing apart and have access to everything, I'll scuff some pulleys, use some Door-Ease, and install a couple of new belts. Fingers crossed.
Thanks to this Forum and especially all of you who responded with tips & tricks.

Ian, I think so. I'm using Gates automotive ribbed V-Belts and the alloy pulleys are from CNC & Sanden. I believe pretty much all standard stuff. The bottom of each pulley's 'V' appears shiny new, while the sides show scuffing which tells me that the belts are riding the sides.

How big is your alternator? It takes about 1 hp to generate 25 amps in an alternator.
And an old rule of thumb was a normal V Belt is good for around 5 hp
So if you are running a 100 or 120 amp alternator you are at max possible with a V Belt

Rod, also make sure you are measuring the v groove of each pulley that they are the same and getting the appropriate width and style of belt. Most of your box parts stores don’t know anything about the parts they stock BTW…ask me how I know. My local AC repair shop put a wrong belt on my after-dealer installed air conditioning on my ‘66 Mustang and squealed like heck and started to wear the edge off with only a few miles on the drive home. Well I had to fix their “repair” that I paid them to do by getting the right belt.
How to Identify a V-Belt?
A V-belt is a wedge-shaped belt manufactured out of a rubber compound, reinforced with a tensile cord specifically engineered to transmit power into movement. V-belts can be found in driving mechanisms, such as engines in air compressors, fans, and pumps.

Check this sight out for some v belt differences. I agree that the GY Gator belts will be the best quality ones that are readily available.

The Goodyear gatorback belts are very good - high recommend.
As Ian said above, v-belts are different widths. In other words, the v-belt width has to be matched to the pulley groove width. If they're mismatched then they won't run right -noisey, come off, wear too fast, slip, etc.

Jerry, The starter, if it cranks your motor over the block must have ground thus the grounding of the alternator would be good. I mentioned it in the way I did after I read post # 6
