Speedo / Tach / Gauges: Turn signal indicator

[rkimmell]

1964 Cruiser with a single turn signal indictor lamp.

Was working fine, suddenly works bright and normal only on right signal. With left signal all exterior signal lights work normally, but no dash indicator lamp.

I took off the wheel and cancel cam, cleaned the switch with contact cleaner, wiggled all the wires with no help.

Any suggestions?

Thanks,
Rich

Wires to the indicator are tapped in to the front turn signal wires. Check all the wire connectors for a loose or broken wire.
Also check the wire going to left front at all connectors along the way. A poor ground at the bulb socket could also be the cause. Anything that creates more resistance than the right side can keep the indicator from working.

It may be possible that the Left Front Turn Signal Housing has a Bad ground, it usually does not happen when the T/S does work, but anything is possible.
It may be seeking ground somewhere else, but still can cause the Indicator to fail.

Many designs of these Parking Light Housings attach the Housing, the lense AND perform Ground all with the same two screws and that can cause a bad ground from too much Paint on the Stone Pan or not tight enough screws because of the possibility of cracking the Lense.
A separate Ground Wire, always trumps the Factory setup.

Thanks for the suggestions

I'll give them a try and post back.

It ended up being a bad bulb. Too simple!

Good, glad it only took you 3 Years and 11 Months to figure that out!

Seriously though, I don't see how that Left Front T/S could possibly have been working fine but with no Indicator, if it was burned out!
