C5 Won't Start
My C5 is dead in the garage. The DIC shows 11.7 volts, the radio works but it will not engage the starter. After going from ON to START there is a click and the dash lights and DIC go OFF.
I have it on a wimpy charger now but something tells me this may be something other than a bad battery.
I had the starter replaced about six months ago.

I've seen batteries with a bad or "dead" cell that would still register close to 12V but not have the amperage to crank the motor. I vote for a bad battery. If it's a side terminal, the corrosion would have to be pretty bad to not carry the current. A quick check of that would be to slightly loosen the terminal bolts and wiggle the connectors back and forth, then retighten.

After you check all the basic stuff like fuses and connections, Get the meter out and start troubleshooting. The Theft Deterent Relay (TDR) is where you start. Check the 60 Amp fuse and make sure that you have 12 VDC on the large red wire. When the ignition is placed to start the PURPLE wire should have battery voltage on it to energize the starter solenoid.
The other side of the TDR is the low current control side.
Heres the schematic that you need:

The terminals were not corroded. I have called the wrecker to take it back to the shop that replaced the starter the last time this happened.

Have the battery professionally tested as already suggested. While the battery is out check your cables. Also, don't forget the various ground straps from the battery to the chassis and from the chassis to the engine. Just 'cause they appear to be tight is not good enough. Take 'em apart, inspect them for corrosion & arcing, hit 'em with a wire brush and reassemble.
If the battery and the connections test OK and the problem persists, you'll need to determine why the battery is being run down. Depending on your circumstances, you may have a quiescent draw, or the alternator may not be up to snuff. One thing at a time, though!

This time the GM tech found the wire going to the solenoid was corroded. He cut off the connect, solder on a new one and it is fixed and has been starting fine.

It was not corroded batty connection. It was a corroded connector on the wire attached to the solenoid and NONE of the high the instruments could isolate the problem. You were right with corrosion
