1990 Cherokee Starting Issue

I have a 1990 Jeep Cherokee 4.0L that will not start. The battery is at
12.5V and there is no "click" from the starter when the ignition switch
is turned to the "start" position. I tested the voltage at the ignition
wire at the fuse panel inside and there was no change when switched
from "on" to "start" position. The only thing that happens when the
ignition switch is turned to the "start" position is the temp. gauge
goes from cold to hot. This just started and I have never had this
problem before. Any ideas?

Do you have 12v at the starter solenoid?

I have not checked. I will check tomorrow. What should I do/check if I
am not getting 12V at the solenoid?

The body ground goes bad on those easily. It is a wire mesh strap from
the rear of the head up to the firewall.

The negative connection at the battery and block or fender also can fail
as well as the positive contacts on the starter solenoid just behind the
battery on the fender. The small pins on the starter solenoid also can
just be corroded.

I would go for the possible dirty connections first before tearing
anything apart.

I checked the braided ground and it is fine. The pins on the solenoid
and they were a little corroded, so I cleaned them up and still
nothing. Could it just be a bad solenoid? How would I check it? The
starter switch is okay. Any other ideas? I don't have any diagrams or
repair manuals available to me here, so I'm at a loss at the moment.
