I put this in general because I have a 1990 G30 chassis MH which uses the same 350 TBI used on almost everything with a SBC on the 90s, so I didn't think it was MH specific.
I recently replaced my alternator with a Reman from CarQuest. I got the "heavy duty" model which is 105A. Yesterday, I thought my voltage was a bit low on the gauge, although its hard to tell on those old ribbon cluster panels due to small circuit busses. So I measured it with everything turned off and it reads 13.4V. When I turn on all of the lights and accessories, it reads 13.1V.
I am not so familiar with older automotive tech. My 2002 Buick has an 85A alternator, but uses almost no power. My 2005 Dodge has a 160A alternator. Both of them measure 14.5-15V, so 13.1 seems low.
My front battery reads 12.4v with everything off and my smart battery charger reads 75% life on it. Is my front battery starting to die causing a low running voltage or did I get a bad reman alternator? Or, is 13.1V acceptable for an older vehicle?
