I made the same mistake - you must spin the alternator faster than the
generator in order to get it up to correct output at idle. Thus, a smaller
pulley is required. I needed a 5/8" groove pulley and found one at 5th Ave
Auto Parts in Clay Center, KS (913) 632-3450. It was a bit pricey, maybe you
could do better at your local wrecking yard. Once the smaller pulley was
installed, I get full charge at idle.
