Hello,I cant find any information about the "excitation type" of my Leece Neville 8RL3021 alternator. Does anybody know wehter it is a positiv or negativ excitation? I want to fit a Wakespeed WS500 on it.

Hi Eloi
The excitation is +ve. You need to disable the internal regulator, and on our boats with isolated negative, where in the Wakespeed manual it says connect to the alternator ground, in our case this should be alternator output negative....not the alternator case or mounting bolt.
