Signal lights
 

I installed signal lights on my 1938 Ford Fordor Delux Sedan. All lights work but flash erratically . How do I fix this problem?

could it be an earth problem? I find a lot of electrical faults can be traced back to a bad earth.

Check all your grounds. Sounds like a classic example of poor grounding.

Are any of the bulbs LED?

I used a Napa flasher but my AV8 is 6 volt .

Sometimes it's the flasher. If it is 6v pos earth use the tridon/novita LL535 ...USA made and avoid the Chinese made silver tin can LL535

Some times the Bulbs are too small to activate the Flasher. Try a larger size.

The NAPA flashers are junk, they are transister style, you want a mechinal type that we used to get, get with Northwestern Auto parts in Grand Rapids Mi and ask for a mechinal they will work,I just went thru this on a 34 truck.

my setup is 12v but i had to get a heavy duty non-transistorized unit to make it flash correctly

Re: Signal lights
 

Would you happen to know the exact name or part no. for the flasher and contact info for Northwestern Auto Parts?

Hi, I want to thank you for your advice to get a mechanical flasher from Northwestern Auto Parts. I purchased one, installed it and my signal lights work perfect. Thank you.

I had the same problem on my 41. Changed the flasher and all was OK
