It is definitely not working like it should. There is a shop that has a 160 amp for 145.00. 1 year warranty and they will throw it on the bench to show me there are no VAC coming from it. Should I keep looking for a 180 or is 160 good enough?Thanks!Sent from my torqued out reuterbender

Well guess what?!?!? I tested it just now and it throws 31.4 VAC. Then when I get that bearing sound it goes down to 27.5 VAC or so. Interesting.... I'll have to start looking for a new alternator I guess. VDC it is at 14.5 or so. However I didn't check to see what it was when it makes the noise.

I'm going to check it again tomorrow just to see. Refresh my memory; how do I check it with the voltmeter? Thanks!

Since I put the battery shims in and tightened the cables and cleaned the pcm ground I have not had any issues. my alt is still putting out around 30 VAC. I can hear the bearings are getting a little growly so it may have to be replaced this year. 275,000 miles and it is still the original alternator.

Do all the terminals; not only the negative ones. Also, clean the grounds that go to the body from the negative cables.While you are at it, do the ECM ground on the firewall, passenger side.

What kind of camper is it?

I tightened/ cleaned all my battery terminals. The grounds were so loose I could turn them with 2 fingers. I installed battery post shims and that works great. I also checked the AC volts at the battery; 30 VAC and just under 14 VDC. I don't remember if I checked it before I tightened the posts, though. I will check it again with the terminals tightened just to see what it is at.I also cleaned the grounds going to the body on each battery and the ECM ground.So far this has fixed the TC lock/ unlock issue for me.
