VCCA Home Forums TECHNICAL - GENERAL Electrical - 6 volt Turn Signals Won't Work, Done the Usual Things

Hello all,

Since getting the '47 Chevy Fleetline running & driving again we've been sorting out little nagging problems. The lack of turn signals has now come up on the 'to-do' list and I can't figure out what to do next. I'm hoping some of the experts here can chime in with suggestions on what to do other than pull out my hair, which I am considering

Here's what we've done: All exterior lights work like they're supposed to, including parking & tail lights & brake lights. Bulbs have all been replaced with proper 6 volt type and wattage. All grounds have been cleaned, all housings & contacts have been checked & cleaned. The car is using a Signal Stat universal signal unit and wiring has been checked.

Here's what happens: Turn signals will light up but not flash. Flasher unit was replaced with NOS Signal Stat original in the box for a 6v system. Plugged it in and it does the same thing. Lights light up, but will not flash.

Could it be a bad original and NOS flasher? I surely wouldn't think so, but what do you think? What could I try next? Should I use another aftermarket flasher and see what happens? Rip it all out and try a new signal kit? Am I missing something simple here?

Thanks as always for the advice!

If your flasher is a two pin ground the case.I have had new old stock flashers not work due to corrosion of the contact points, they will stick together.

Thanks a3alf, its not a two pin, its an oddball long type with three wires and a screw that attaches the case to a ground. Its mounted to the dash bracket. Dash is a good ground since the dash lights work using the dash gauges as ground. (I think?)

Do I need a separate ground wire? I could try some alligator clips and see if another ground on the case works.

You might also try tapping the flasher can edge on a solid surface. Rotate a bit and tap again until you have gone around completely. If the points are stuck together it should vibrate them apart. Don't hit too hard or you risk bending the point arm and then they will not make contact.

Chipper, you are a lifesaver. I actually split the case of the flasher unit and saw a little corrosion on the points. Never knew that's what was inside there! A little emery cloth and a screwdriver to move it back & forth a few times and we're in business! It was so nice to see them flashing on their own! I owe you one! Thanks,

Here's what it looked like:
