Any Ideas

[Jerry Hall]

Someone sent me this picture. I have no idea where it came from or how he came by it, or even if it's real.

That should clear up the radio static.

Back in the late 70's my 70 r/t se. Kept having spark plugs go bad. So I tried non resistor plugs and that solved my spark plug problem.. and I didn't have any static on my radio either. But maybe the resistor plug wires were doing that job? And a couple of other weird things with that car was it had a electrical problem although temporary (it fixed itself??) The headlight delay timer would turn the headlights off in a few minutes along with the headlight doors closing ! Fun to watch! And the other weird problem the car had, was certain electronic devices would turn on within 30 or so feet from the car. When the car engine was running. I still remember the cars. Vin # XS29UOG118943 anyone else have or had a haunted car?

Yes, back in the 90's the original thumbwheel AM would only produce garbled noise like a blown speaker at a burger king drive thru 90% of the time. It would randomly pop and it would play perfectly. When would it play normally? Usually after cruising for hours on a saturday night and about 100 yards away from putting it back in the garage it would pop and play normally. Go figure.

Back in the day ('50s) there were "doorknob" capacitors, that looked like each half of this monstrosity. That being said, a rectified signal (DC) comes from the alternator, so it cannot cross a capacitor. The capacitor can filter any ripple on the output, but that is to ground. Something I do notice is it looks to be missing one of the diodes by the output stud...

I'd bet on some goofy grounding problem.

I've heard alternators make a heck of a noise through the speakers when you had the radio tuned to a AM station. It wasn't the plugs or plug wires doing it. This was a whining noise. A capacitor would normally fix it if there wasn't a bad ground causing it.

2 different 66 Plymouth Belvederes and both sedans. Every now and then I'd get in and turn the key and nothing. Everything would light up though and only the starter relay wouldn't engage. Slam the floor board with my foot with the key in the start position and bingo. Another thing with both cars is without a key in the ignition, I could turn on the turn signal lever (didn't matter right or left), turn on the wipers, radio (one car didn't have a radio), fan, whatever, everything would move or sound intermittently in relation to the blinker. Tried several other cars and they didn't do it.

Dad's 70 Challenger did that. Iirc you had to turn on the 4 way flashers.

My first Belvedere had the 4 ways but my present one does not. Not even sure anymore if I tried it with it but did have several Challengers but don't recall trying it with those either. Dang, Oldtimers lol. Both Belvederes had the same hiccup with the starter relay though and it didn't matter if the relay was replaced or not. Used to open the hood on my first car and start it by crossing the relay. When my present one did it the first time, it started pouring rain and I made it to the car and got in just as the bottom fell out and didn't feel like getting soaked. That's when my brain worked better and tried the work boot to the floor deal and it started lol. Wasn't sure if it was doing the same thing as my first Belvedere but when it started, pretty much felt it was....

Both my 68 runners the radio would play with out key , flip turn signal - turn on 4 way flashers and then rest your foot on the brake .
I think Ma mopar had Forest Gump working as an electrical engineer .

Bad grounding on the instrument panel & switches does the weirdest things.

 

[Slap Stick]

That's what I couldn't remember! For that to happen you also had to press the brake pedal.
Fan, radio, and wipers would pulse and the turn signals would flash in a weird pattern.
