As I have posted here before, I just completed the two week installation of a new fuel pump. My first step was to see if I could develop fuel pressure, this I did by attempting to start the motor. There was no sign on my pressure gauge, so I cranked it, hoping to start, about 5 times. On the fifth try, all electricity suddenly failed, completely and totally. There were no longer lights on the dash, horn wouldn't work, etc. I believe, but cannot swear, that I saw very light smoke, similar to cigarette smoke, come out of the dash. There was no "sound of failure" that I can recall. I have nothing to test the battery with, but it appears to be dead. Is there any primary electrical connection which might cause such a total failure of electricity?
The driver's door had been left ajar; this might have drawn the battery down. However, it did crank normally several times, the loss of electricity was not gradual, it was sudden and complete.

Open up your jump cover on the fuse box under hood and inspect the primary cable coming up from the battery. Look for dark corrosion or signs of duress there.
Of course, battery connections under the trunk floor mat first.
Modern cars will crank fine but no start due to low bus voltage to the electronics.

I have checked all of the connections I have found, no looseness or corrosion. I think it is important that the electricity did not reduce, it shut of like a light responding to a wall switch.

Ignition switch sounds very plausible, embarrassed I didn't think of it. I have a parts car, I'll switch it tomorrow. Other suggestions still welcome.

There are some heavy-duty fuses near the battery, 40-50 amp fuses, 11E/4 and 11E/5 supply the CEM, I'd check these fuses.

I think first effort is to get a fully charged battery installed. Nothing good to test unless you have about 12.5 volts available.

That was in fact the problem, I am truly embarrassed not to have thought of it, particularly since I was operating the switch when everything failed. My thanks to all who responded.
Now that I have electricity again, I can continue my three week project of attempting to pump fuel from the tank to the engine.
