1974 Brain Box saves the day.

I probably need to learn the multimeter better.

Looked like open one way and not on the other.

Think there are thousands of new brain boxes on the market for sale now, just need to find who makes the good ones and not the el' cheepo models.

Kind of like @Mike69cuda is saying semiconductor technology has changed dramatically in the last 50 years. The new style boards are 1/4 the size of the old boards, regardless of where made. Just got to spend a little more money on some of the better units.

I have 2 new old stock USA modules here now as spares, so I am covered.

Searching out the best made new modules now that prove reliable. Anything $100 or less for a mopar brain box is still a great value for one that works as it should.
