Charging system quit on my Ramcharger the other day. Pretty sure it's the alternator but want to confirm.
If I put battery power to one field terminal and ground the other, it should go full charge right?

turn key to run, alternator pulley should magnetize with small screwdriver touching it, means alternator is ok
all parts are sold as is, all parts are considered used no warranties or returns
paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred
site is not monitored 24/7 there might be a delay in response

It's dead. Already swapped and back to charging.
3 month old alternator and 44 year old everything else.
They just don't build things the way they used to.

3 month old alternator and 44 year old everything else. This was my question from the first post, what year? 1980 Were they still amp gauge or did they have a shunt? Both were problematic. That's why they stopped using them and have a volt gauge now.

you should probably replace the VR too.
I have had a few go bad and kill off an alt at the same time. not sure why. but I almost always wind up replace both parts. Been burned by the "quality " of aftermarket parts too many times over the years. If I have good functional OEM stuff I won't change it. See the current situation for example.

They just don't build things the way they used to. 3 months? You must have bought the premium brand i only got 2-1/2 weeks on my last lifetime warranty alternator. I would call the stuff they sell today crap but crap is better than this stuff. Glad its fixed.

That's why they stopped using them and have a volt gauge now. It's an 80 and the ammeter has been bypassed for years. Old style smoke machine. Being a 80 it should be a shunted system, so bypass or not the amm will make nothing, since these ammeters are a remote signal readers between both sides of the shunt path, not like older full load ammeters. At least on passenger cars. I guess by this year trucks should be the same.

One sounded like it had sand in the bearings and the other had been dropped.

This had the shunt style ammeter. 90 to 93 had a voltmeter. Change over might be 91.
