About 6 years too late im afraid but for any one else that finds this forum my local sheriff's office search and rescue had this dilemma. They added a 100 amp chevy one wire alternator mounted above the original 24v, the original 24v alternator had the three belt so we used the empty forth. All the accessorie lights and radios were ran off a power fuse block distributor. I do not know yet of any problems. Ive personally think it works fine ive had to replace the 12v alternator twice cause im cheap and buy the carquest remanufactored ones.
