Goofy Blinker
Hey guys,
Ok here is what is up now. I was working on my light system (77 150) and noticed that my right blinker wasnt working right, so I put in a new blinker controll (looks like a little round canister) and it fixed the first problem but I discovered another. When my lights are off my blinkers work fine in both directions but when I have either my clearance lights on or my headlights the left blinker works just as usual but the right blinker comes on very dimly and doesnt flash, it just stays lit up. I have had the whole rear end of the pickup rewired after having all of the wiring ripped out in a snowbank I tried to bust, so I know the problem isnt there. Anybody have any ideas????? Thanks for the help

Sounds like a bad ground. Doesn't matter if the wiring is new or old, I would check the grounds at all sockets first.

Nitro, You could have two wires touching (maybe). Your running lights are on the other filiment than the brake/signal, so the two shouldn't have anything to do with the other. As preveosly posted check your grounds. Run a battery post brush into the bulb holder. It's working so grounding is first check.

Bad ground, meaning it is either missing or really corroded. The running lights are getting their ground thru the signal light circuit instead of the ground.
Check the ground tab in the sockets,front and rear, and also the ground stud which should be about 6-8 inches from the socket. The ground wire should be a black colored one.

Check your bulb socket. I had really intermintent problems with one of my blinkers and swore up and down it was a wiring problem. It ended up being a partially rusted connection within the socket. The replacements are cheap and readily available. -My two cents.

Had another thought, make sure that someone has not put (forced) an 1156 bulb into a socket made for an 1157. Ran across that one on the 66 mustang. Sometimes PO's really bite.

Here is a little diagram as to what happens when you have a bad ground in circuit with a dual filament bulbs that most American cars use. The backward current flow can find it's way through many things up front in the dash area and cause strange things to happen.

Ditto on the ground problem. This causes a feedback of current that causes odd things to happen.
