Good evening. I have caused myself an unusual problem and I don't know what or how I did it. I bled the brakes and now the Expy won't start. No electrical power anywhere.
This is what I did:
Turned the ignition to On but not Run. Pumped the brake pedal several times then rested weight against it. Turned everything else off - a/c, stereo, auto exterior lights, interior lights. Closed the doors. Bled the brakes. Got distracted by my wife asking for help and left the vehicle. Hours later she went in the garage and came back asking about a ticking sound.
I go out to inspect. I hear a rapid-fire ticking sound -- several times a second. I check under the hood and touch all the relays. A tow connector relay is vibrating, so I pull it. All other relays are not vibrating, and the sound disappears. I then check all the under hood fuses and see a 20A cig lighter fuse blown. I pull that too. All other under hood fuses are ok.
I then notice the headlights are flashing very dimly on the wall. I open the door and hear a muffled rapid-fire ticking. I pull the passenger fuse panel cover and it gets louder. I touch the big relay in there and it is not vibrating. I pull the relay anyway but the sound continues. I test every fuse and they are all ok.
I cannot find what is ticking inside the car. If I turn the key to On, the ticking stops. When I take the key out, the ticking resumes. I tested the battery connected, and it showed 6+V. I disconnected the positive cable and it shows 12+V. (Naturally, the ticking stops w/ the battery disconnected.) I now have a wall charger on it just in case (+ cable still off though).
I do not remember touching anything under the car or under the hood and unintentionally completing a circuit. My 1st thought was that by leaving the key in On, I had drained the battery. Now I'm not sure. I hope I didn't screw up the ECU. Is there another relay or two hidden inside the passenger compartment?

The tow connector relay I pulled is good.
