e bought a a couple prestolite alternators I installed one and the bus didn't detect the bus having an alternator . I am not a strong electrical tech . Any way does it need to excited ? If that's the problem then how do I excite . Second thing is there were 3 terminals to put the wire from the ignition . I I can't remember what stud I used . I will try and update where I installed the igntion wire
I contacted Prestolite support and found out I didn't' nee the ignition wire on the alternator . Had warning that the bus didn't recognise the alternator and pulled the relay and it is working
