Well Crap

I'll have to borrow a fluke from work since my dvm is real basic.

Try using ur basic DVM. You will know in 2 secs if it contains the dc block caps. Better yet, just borrow a fluke from work...(make sure the 9 vdc battery is good) . I just edited my post above you with more info. What year is ur car, auto or stick..and how old is the alternator. If it's > 10 yrs old, it would be suspect. But if it tests ok on the fluke, then at least u can scratch the alternator off ur list. Bad alternators have cause no end of grief to folks while trbl shooting....'phantom issues'.

I replaced the alternator in 2017.

Just test it. I have been through 5 and one was bad out of the box at the ford service center. I have since switched to a 2010 alternator and haven't had an issue yet.
