1958 left blinker not working (need help)

Re: 1958 left blinker not working (need help)

Daniel, When you get your bulbs out to check for proper bulb#'s, here is your reference data below.

Make sure yours are 1034's. If they're 1157's, the candlepower spec is different and could cause your "unknown" flasher to be inop only on one side. Also ensure your dash indicator bulbs are #53.

Any variation of incorrect bulbs can do some strange things.

What flasher is installed? A original or a generic replacement?

Again, as mentioned, grounds cans also be a issue. Highly resistive ground connections can cause downstream bulb filaments to be used as the other bulbs ground path, seeking a path to a good ground.

We understand you may have put this aside as other priorities may have taken over your time. We're all waiting to hear back from you with status when you get back to it.

I solved the problem and wanted to share the solution.

After following all the suggestions above.

While I was checking the new 1034 lamps...I noticed while the switch was on parking lights, that the left front parking lamp was brighter that the others (ie. the turn signal element was on, not the running lamp element).

So, I checked the wiring diagram and the wiring at the connector was correct (matching colors)...I decided to swap the purple & blue wires that go to the light assembly and that solved the problem and it works correctly now. (typical as what Tom did on his rear lamp socket mentioned in post #7)

Another new lesson learned! Dan

Re: 1958 left blinker not working (need help)

Dan, good find. Are they new Park lamp assemblies?

So it turns out exactly that the wattage difference of the 2 elements created the problem as the flasher wasn't getting triggered due to the lower wattage of the "park" lamp portion of the bulb. I.E. not enough current flow in the flasher heater wire.

So I'd think the harness is OK, but the Park lamp socket is wired wrong.

Tom, is that what you concluded? The harness was ok, correct?
