Does anyone know the differences (aside from the output) between the Plane Power AL12-P70 and AL12-C60 alternators? My airplane has an Al12-P70 installed, but upon closer inspection it looks like it is for a narrow belt. The belt sits too high on the pulley. It works, but not sure it is the correct model for this engine/belt combo. Both are listed as applicable for the aircraft and/or engine so just curious if there are pulley differences.
