SC-2 & Cab1 L Problem

My first guess is- you didn't configure the SC-2 for the correct "mode" during the programming process.

The SC-2 is just relays. It's pretty darn simple from a wiring perspective.

Again, my bet is- you didn't ensure the mode of the outputs was correct, and so it's in an "accessory mode"- hence you only get one direction.

The SC-2 is designed for three operating
modes:
1. Control four switches through the left
and center terminal blocks. Control two
momentary and two on/off accessory func-
tions through the right terminal block.
2. Control six switches using all three
terminal blocks.
3. Control six momentary and six on/off
accessory functions using all three
terminal blocks

See page 22 for
instructions to program the SC-2 in switch
only mode.

Please get back to us after doing Vernon’s suggestion. It should correct the problem. I’ve been using SC2’s with switches for many years without any problems.

Also, try a different channel.  I've had several SC-2's fail and I had to replace a transistor to get the channel to function properly.

Thank you @Vernon Barry, @romiller49 & @gunrunnerjohn!

That was indeed the problem.  I reprogrammed it for switches only and it works flawlessly.  I was racking my brain all day and it turns out to be something really simple.  I must have missed reading that page in the manual.  Thanks again....this is what I love about this forum!
