Here’s a new one

[Hootbro]

I had a feeling you were brilliant beyond what we see.

Thanks, but I am probably along the lines of I just know enough to be semi competent but still a little dangerous. We got other engineer Velcro shoe wearing Rain Man type savants at work that could explain it better than I can.

check your flux capacitor

check your flux capacitor

I thought that kicked in at about 88 mph

 

[Rocksalt]

yes when operating correctly

I had a flux capacitor tester.......but blew out caps in the power supply. Need a new one.

holychit!
That thing use electron tubes?

LOL - yeah. When I worked at Compressor Controls Corp one of the engineers there had used this and some other equipment when he took some classes and asked if I wanted them. Yeah, I got them - and I used the scope for my alternator testing - to check for excessive ripple, test the diodes under load, stator windings under load, that sort of thing. Well, it was rather old then, finally blew the power supply caps. I really liked it as it was set up perfect for my alternator output pattern testing and load testing - bummer, it's broken.
So I need to get it fixed or find a replacement for it.
I'm using an automotive engine scope now and it doesn't work out well for this sort of thing.
I've thought I'd actually pay to get it fixed - but don't know anyone who would touch it. I believe it's only the power supply that's toast.

How integrated is the power supply? Is it possible to remove/disconnect it and replace it with something external?

It's part of the system, not like a PC. It's a board, but the thing is wired into the main boards with multiple outputs if I recall correctly. Been a while since I looked - saw the exploded caps and set it on a shelf.
I suspect a person better than I am at electronics could repair it.

I've built small things, like I have a replacement voltage regulator circuit I've been working on to replace the Motorola external voltage regulators used with AMC cars and Jeeps of the 60s and 70s. It's working pretty well, but I need to get temperature compensation figured in somehow. The originals charge slightly higher in cold temps, they have a thermistor and change the regulated voltage based on ambient under-hood temps near the battery. Mine regulates a steady voltage regardless of the temperature.

Anyone notice anything out of the ordinary? I pulled up to the house and turned the Jeep off. It was stuck at 10mph on the speedo. Turned it back on and the needle flickered and stayed on 10 mph at a stand still. Turned it back off and now it’s working. Any advice to what problem I may be experiencing?

Did you turn off the engine while still in PARK?
