Default Electrical Problem

I was removing my starter and the positive lug on the solenoid broke off (a common problem I have read). The lug was hanging loose with the battery positive cable and the alternator charging cable connected. I had to roll up the window, so needed to restore electrical power. However, I did not check the location of that loose hanging lug, so when I connected the positive cable to the battery, the lug shorted to ground (I think it was touching the exhaust). I disconnected the battery cable, moved the lug away from any ground, and reconnected. No electrical power. Cannot roll up that window. Cannot get accessory mode to come up on starter button.

I do not think that anything can get damaged by shorting the positive cable, other than the cable and/or the battery. I was going to check the battery voltage, but my voltmeter had dead battery. Am I correct?

You probably have some blown fuse's due to a direct short circuit.

Make sure you check the high current square fuses. Several under the hood and one in the foot well.

Trying to understand how the fuses could pop. A dead short should send the current to ground, the path of least resistance. How does it flow into the rest of the power distribution system?

You sent a short circuit through ground of the entire car and everything electrical in the car is grounded somewhere. It also sent a shock through the alternator circuit.

Your main fuse probably blew. Starter fuse 40A in engine compartment.
While your checking fuses, check the one for the Alternator as well
Horn/Alt/Sense Fuse 15A (however, it should be OK)

There is a starter fuse 30 40A in the under hood fuse block. Also a fusible link between the alternator and starter motor.

When pulling off the power supply, I think it is best to leave the windows down. Without power the windows will not index and doors won't open/close properly.

Also if the doors are closed and the windows are up and with out power supply, you will have to go through the trunk to release the doors.

If I plan to disconnect the battery I put windows down first. Down first, so I can easily open and close the doors and if closed, just reach inside to the floor release lever to open. Hopefully you have a dry place to work and can leave the windows down...

Keep us posted on what you find out.

Yes it is! I lost a couple nights of sleep worrying over what damage I might have done when I shorted that battery cable. Now I just need to finish swapping the z06 exhaust for the stock so I can get the California recall done.

If things go as planned, I will sell my C6 next year and get a C7 z06. I will not modify anything on that car. Too many headaches in California.

I am not in California, but I just ordered a 2016 Mustang GT to replace my Acura and all I plan to do to is drive it and routine maintenance. My Vette taught me to leave well enough alone. A stoked LS3, coilovers and all that stuff is fun, but never ending and I am just tired
