You said it is a new rebuild alternator? Check and see if it self excites after disconnecting the plug, Just had a similar situation on a 2090 Case ag tractor that had the 10SI 3 wire alternator on it, with the SE alternator on and the plug in hooked up it the charge light would be lit constantly and the unit would work and charge normally, the solution for this farmer was to let the charge light/ exciter wire disconnected. See if it starts and charges normally hooked up 1 wire, If the light goes out when the plug is disconnected shut off look at the alternator, don't over complicate things do the simple stuff first
