Sean,
The use of dual belts has become a common practice since many of us have upgraded to alternators with increased outputs, 100A, 130A and larger. I run a 200A HEHR Powerline alternator and Isolator. I find it strange that you're loosing so many alternator belts. I ran my 100A alternator ( AZ DL-7157 ) for almost a decade without loosing any belts. The 200A I have installed is a dual belt system. Some have started using the GM CS-130 alternator (Gary K.) The best place that you can get the dual pulley is Jim K.

You may also find them at some of the big box stores or an Alternator Rebuild Shop.
Just buy your belts as pairs and replace as pairs if you have to replace. Never just change one and the belts stretch in use over the life of the belt.

Dry camping at races drains my battery and then it pulls to hard when I leave and snaps a belt. Is there a double pulley setup available for these or should I put on a smaller alt so it doesn’t pull so much when it is down on voltage? The Fuel injection really does not work well once the alternator quits. I just fired up the gen and drove home with it running to keep the batteries up since I was only a couple hours from home. Just looking for a better way to keep it it all working. I should have run the gen more over the weekend but I really don’t like hearing it run very long.
