I have repaired mine a couple of times. The SGC documentation
is very good. Have you checked the four lines between the
Smartlock and the SGC-230? If the notune line (white wire)
is at ground, the tuner is in perpetual reset. The notune
line should be at a plus voltage when the reset button
is not pushed and go to ground when the reset button is
pushed. The digital control portion of the tuner is super
easy to troubleshoot and a good technician should be able
to diagnose and repair minor problems. All of my problems
have been minor and easy to repair.

The most nagging problem was when the tuner wouldn't tune
while my pickup was in motion but would tune just as soon
as I stopped the vehicle. It was a loose nut inside
the box on the output feedthrough insulator.

Have you tried the tuner without Smartlock in the circuit?

Just doubled checked without the Smartlock connected. No change. I did
notice that the braid of the coax where it connects to the terminal inside
had broke off. Re-soldered this and its still the same. This was due to the
big plastic nut on the back being lose and allowing the cable to turn.
I wish I could fix it myself. But I would have to be talked through how to
check the components to see if they were ok or not.

Do you know any fellow hams who are electronic
technicians or engineers, preferably electrical?

Unfortunately I don't know anyone.
I have been off the air for a long time. After the move to here and having
very good neighbours I am able to get back on the air. Well until the tuner
stopped working.

I did find this PDF doc just now. I have the model after the year 2000.
