Ok, I need to run a question by you professionals. My tractor is in the shop for some maintenance and sensor malfunction. They tell me the alternator is charging off and on. They remove it and take it to an alternator shop to get it checked out. Find out today that the alt. shop hooked it up said nothing was wrong with it. NH mechanic puts it back on and says when the rpm's are below about 1600 it's not charging all the time and when it goes above that it charges fine. So I talk to the mechanic today and he gives me a couple options. 1. leave it alone and if the battery light comes on just make sure you have rpm's high enough to kick it off (which all of my mowing of course is above that 1600) and he says it may last 10 months or 10 yrs. says this is what he would do if it was his. 2. Replace it with a rebuilt alternator which they said is almost $500. Cheapest I've found on line is $395. I was told that if something had been wrong with it the alt. shop they could rebuild it for about $75. Mechanic thinks that the alt. shop hooked it up to their electric motor and it probably simulates something over 1600 which shows it's working correctly. I think I'm going to have the service mgr. call the alt. shop and see if they will just open it up anyway and replace whatever they replace when they rebuild them and then put it back in the tractor. That way at least the insides are replaced and if it works.. great and if not, I'll just keep it high enough for the light to stay off. Sorry for the length...Any other ideas?? I find plenty of replacement alt.s online the say for the TN75D, but they are 45 or 65 amps. Mine is 85 and can't find anything but NH rebuilds.
