Electrical: Turn signal instrument panel indicator doesn't come on in right turns...

[Bill Pressler]

The right turn signal out back works, but the instrument panel indicator only works during left turns. Any ideas? Thanks.

Burned out instrument bulb!

If the Car is a '64 or '66 Lark Type there is only ONE Turn Signal Indicator so since it is working on Left it's OK.
Check that BOTH Front and Rear Right Signals are properly flashing,

The Front Parking Lights ground through the Mounting Screws and there may not be enough bare Metal to work.

Also check that the dash Indicator Bulb Socket is firmly tight to the Dash and grounded.

A Jumper wire from the Bulb Socket to the Bumper or Bumper Bracket, will make the whole left Circuit work if there is a poor Ground there.

new paint or old rust can necessitate making separate, new grounds..... I find this to be a great help, especially after a repaint.

Thank you gentlemen; I will check each of those areas out!

Hi, Bill!

Your '66 uses a two-prong flasher and has a single "tell-tale" indicator. The indicator socket is powered by two wires that come from the turn signal switch. Depending on which way you are signalling, these wires alternate in providing the 12V pulse and ground. If the left side works fine, and your right side front and rear are both illuminating but the indicator is not, the problem is in the turn signal switch itself. This switch appears to be 1551930, and is available from SI or Stephen Allen for $75. Changing the switch involves removing the steering wheel.

I recall having this problem on at least one of my '64s. The CASO solution is to just leave it alone, as long as the signals work. There is also a CASO fix that involves splicing into both of the turn signal wires with diodes, feeding these to one wire of the indicator socket, and grounding the other wire. But, as pristine as your Cruiser is, I would go for a switch replacement.

Thanks, Jim. My initial impression is to do the CASO thing...nothing!
