[V8] Electrical Issues, related? - Problems fixed but not related

[Joe Griffith]

I don’t believe any of the symptoms were related.
   
  The turn signals just started working again on day, but I have since replaced the steering column switches and all is still well.
   
   I replaced the voltage regulator and the pulsating in the lights has gone away.
   
  While researching the radio problems I noticed that the brown ground wire that is suppose to be in the plug connected to the back of the radio had been removed and taped up.  The radio had been working perfectly before, but I decided to put it back in the correct place, but still no luck, then I touched it to the back of the radio case and it began to work, so I just attached to the radio case.  This seams to work but my reception is not as good as it use to be so at some point I will try to figure out that issue, but for now its O.K.
   
  Yesterday I found a battery at Wal-mart, its much smaller but it comes with a 2-year replacement warranty so for $52 I thought I give it a try.  The car turns over much quicker now.
   
  Thanks for all the help

  I checked for water around the passenger side foot well and it was dry, and there were no blown fuses.  While I had the carpet out I checked the grounds in the foot well area and all were good, as was the ground at the battery.
   
  I did notice a wet carpet on the driver side under the accelerator pedal not long ago but figured it can from my shoe and never investigated further.   Is there a ground somewhere around the trans tunnel that might be the culprit, and if so is it easily accessible?
   
  I checked my Repair Manual and it lists ground points but gives very general description of location, and what does “welded, in dashboard harness” mean?  Is this harness grounded somewhere else, say in the passenger foot well?
   
  Thanks for the input

carpet out first and see if the foam on the back is wet. Also, check around 
the fuse box for water. The problems sound related, but only in that region. 
There really isn't any other connection. Are there any blown fuses, BTW?

I'm wondering if anyone out there knows if some electrical issues I'm having 
with my 91 V8 may be related.

Some background, the car sat from March till about 3 weeks ago with a 
badly leaking hydraulic hose and rack. During that time the battery drained 
to nothing. I jumped it occasionally when I need top move the car around my 
driveway, but it never held a charge for very long, and the dash lights 
would slightly pulsate brighter, dim while the car ran.

So while I fixed the leaks I put the battery on a slow 2amp trickle charge 
for about 10 hours.

The car started and ran fine without leaks but the dash lights continued 
very slightly to pulsate (barely noticeable). I drove the car that night 
and the headlights also pulsated.

So I figured I'd order voltage regulator and put it in when it gets here.

I drove the car about an hour to work the other morning with the lights on 
and the radio playing without incident, but when I got in to come home the 
radio wouldn't work. The faceplate would light up with the dash lights, but 
when I turned the knob it would go black.

I put a Gamma radio from a 91 200, but it doesn't even light up.

I drove the car the next day and nothing had changed, but the third day 
the turn signals stopped working.

Any thoughts on if these cars have a way of isolating unnecessary 
electrical devices?

Thanks for you time

Joe
