hi. Would anyone know which one of the 2 wires that goes to the alternator is the one that energises the rotor. Is it the thick or slightly thinner one.
We want to stop the alternator charging during a race but want it to charge while running round the pits and waiting to race. Am I right in thinking we can do this by adding a switch to this wire which we can flick over just before the race.
Was hoping to switching the thick wire that goes to the same terminal as the tell tail light would stop it charging. Was hoping this would make the light come on so he would known what's it's doing. I suppose the thing to do it try it.
