Sorry for the delay... life happened.

So, I was able to test 1REC with a bulb and power supply and it works fine as far as I can tell (switches on and stays on with a momentary positive voltage to the gate).


3 & 4 REC are questionable. Maybe you can tell me. Here's what I did:

* I removed the flexible ends of both and isolated them.

* I left both REC 3 & 4 mounted to the plate. It seems to be common between the two.

* I clipped one end of my digital multimeter on the flexible end and put my other probe on the base plate they are mounted to.

* On the diode closest to REC1, I read 5 Megohms one way and 1 Megohm when I switch the leads.

* On the diode closest to the edge of the SCR panel, I read 1.5 Megohms one way and O/L when I switch the leads.


I still have to check 5REC and 2REC but those diode readings might be telling.

What do you think?
