[DML] Re: ALTERNATOR OUTPUT

["jchapelhow" <chapelhow@xxxxxxxxxxx>]

John.

Many of my weird and not so wonderful electrical problems were down 
to the common ground point behind the middle panel. My problem was 
more severe in that often there did not seem to be enough electrical 
oomph to drive more than one circuit at a time, ie I could have the 
lights on but not indicate at the same time, often the car had to be 
deliberatley rev'd just to get the indicators to work. Attempting 
hand signals in a DeLorean is interesting....

The centre control panel switches AND the voltmeter on my early car 
all take the ground point from behind the hazard light switch. 
My 'electrical' section in the files area has a photo. If your radio 
can be removed easily you can get to the area from there. You could 
then tighten the bolt, which in my case held no less than 9 grounding 
wires. It is also possible for test purposese to run a temporary 
ground cable using a croc-clip and run it directly to the battery 
post.

With the temporary ground connected/disconnected I could create my 
problems at will, the voltmeter voltage shown on the gauge altered 
from 6-8V disconnected to a 'true' 12-13.5V with the cable attached.

Drops just around 8 volts, yes that low @ IDLE!
With A/C and lights and radio on, it was fine six months ago when it 
was running before.  Then radio shuts off and of course comes back on 
after I give it gas.
Aftermaket AC Delco ALT., (maybe a year and a half old) I believe 110 
output but I have to check.  
What could be the cause just started the other day and have not had a 
chance to diagnosis?
