inserting or removing? the CAT cable with power on is like playing Russian Roulette.

Best idea is to never plug or unplug anything with power on.

Agree! I certainly didn't do that but I 'may' have started or killed my car at some point. I don't remember. I know I've done that in the past w/o a problem but maybe in the extreme cold? Going forward I'm going to be super cautious and make sure the rig is OFF when starting or stopping the auto engine. I'm also going to leave the MFG ATU with the alternate power connected.

On a different note - I, just now, received a reply for Yaesu for the fuse. $0.67?+ s/h?+ tax?+ whatever. Is it worth replacing the car fuse with the SMD assuming I'd be soldering to the end of the newly installed leads? WFIW, If I'd gotten this earlier that is probably the way I'd gone.

You guys sound like the conversation that once took place in the cockpit of a DASH-8 aircraft;
"Hey Bob, ever wonder what would happen if the lift spoilers were to be deployed while in flight",
"Gee Lou, that's a good question, let's find out..."
Spoilers deployed...
The next sound heard is...
"Holy crap, with those things out, this bird falls like a rock!"? yelled Bob over the screams from the passenger compartment, "Better retract them before we hit the dirt, Lou!".
And now every DASH-8 n=manufactured since this incident and all those manufactured before the incident cannot deploy the lift spoilers unless the aircraft is firmly on the ground.

Kinda like killing power to the rig before you unplug cables that carry power of signals within the rig.

Stay safe guys.
