[DML] Dead electrical: Problem & Solution

["Nick Kemp" <nkemp@xxxxxxxx>]

In short, the negative wire where it connects to the frame (near the
passenger leading end of the trailing arm) developed a poor ground
connection to the frame.  I loosened it and retightened, all problems
solved!
 
Here are the symptoms in case you experience:
 
- Started just fine
- Noticed the radio was rebooting a couple times as I pulled out of 
garage...weird.  and it wasn't playing Ghosts In The Machine
- Drove it about 1.5 miles to destination no trouble and turned it off
- About a minute later I tried to restart and it was totally dead. 
No clicks, No lights. Nothing.
- 5'ish hours later I was ready to pull it home and the lights and 
door locks were working again. As soon as I turned the ignition 
everything died.  No Clicks, No lights. Nothing.
- No fuses or circuit breakers are tripped
- At home I put the meter on it and noticed that the car body and all 
other exposed metal was at 12.5 VDC when measured against the ground 
terminal
 
Since I had a poor ground to the battery, and since something was on in the
car (light, electronics, clock, etc), voltage was flowing through the device
to the car ground and the car ground was floating.  When I measured from the
body/frame to the negative terminal I completed the circuit and voltage
readings were 12.5VDC or there about.
 
One more case for the log book about the DeLorean's poor grounds.  
 
Next time you are near any of the grounds, it may be worth retightening to
break through the corrosion
