Review on 🔌 High-Quality Delco 10SI 1-Wire Alternator Replacement, 63A with V Belt Pulley - Ideal for Buick, Cadillac, Chevy, GMC, Oldsmobile, Pontiac - Part # 1100125 by Jermaine Batista

My 1977 Bobcat 720 4 wire alternator/regulator has failed. There was definitely no controller on the shelf. I decided to change it to a single wire design and therefore less spaghetti under the cab. The alternator was an exact replacement for the 10si block. I replaced the pulley, removed the fan and put it in the small hole. Fired up an old Wisconsin 4 cylinder and charged it to 14.2. I lowered the cab and thought no more about it. It works much better now and I worry a lot less about the regulator being in a bad spot and being exposed to water. No more external regulator, no more worries.
