Changed the Alternator on my M923 yesterday. Used a 24v automotive style. Had to drill the holes on the MV bracket to accommodate 1/2" all thread. Also had to open up the slotted bracket with a grinder to accommodate the 1/2" bolt up top. Good news it only required Pos & Neg cables to be hooked up. The other 2 are zip tied off so they don't touch anything. Furthermore, if I have future problems (like swamping it out) I can pick up a replacement at most auto parts stores now. I initially tried to have the MV alternator rebuilt. Repair shop said "no way" he couldn't get parts for it. It got real hot and windings were shot and it had voltage regulator/rectifier issue so not putting out charge. Ordered 4 new shackles (D-rings) as it was missing 2 and bent 1 last time it was stuck. Yet to come is new water pump, bearings going out in the current one, pulley wiggles. New belts, new diff and transfer case fluids. I have 1 broken bow for the cargo tarp, rotted so it snapped. That's also on the "to fix" list. Oh yeah, lastly, the starter or solenoid keep giving issue. Intermittenly when I try to start, nothing happens, just click, click, click. I have to use a screwdriver, jump the solenoid for a split second, then I can start from inside. My buddy says it looked like the ground was loose. So I need to check that out, tighten everything. Otherwise, guess starters coming off to clean/inspect and R & R whatever the problem is.
