We just replaced our alternator 6 weeks ago with a Bosch 200Amp School Bus alternator. The sense wire is wired differently, and my ign wire is not connected. (This is #5 for us, all previous were the Leese Neville, 160A.) Call Jim at Smith Auto Elec in Yakima. Ph 509-453-8275. He is very helpful in working with you and will advise you on installation. We will drop off our old alternator within the next two months so he could dissect it and determine the cause of the failure. Also, Jim can look at our Apex wiring and how the electrical pieces interrelate.
