New switch cured my problems.

My experience with repairing a couple of these is the switch is probably bad.

The one I repaired had been too hot and was intermittent.

Just a guess?

Sorry if this shows up twice.  First time didn't look like it went through...

Okay, I have used my S4 tuner many times with the only issue being the red LED didn't usally go dark. Well I pulled out the S4 for the BJ London calling event and it didn't work. No spot on the inductor gave ANY lights, and it seems there is no signal coming out of the tuner. Tuner feeds a MFJ tuner that I use as a power meter when using the S4.
 
Any ideas where to start looking?
