Led flasher in '40 ford

[Brooks]

Guys, I have a problem with my led flasher all lights will flash when motor not running. With motor running the lights will flash very fast or some time not at all just light up. Anyone had this problem. I have a 12 volt system with the correct led flasher that came with the taillight and park lights for 1940 ford. Thanks for all your help. Have a nice day.

When weird things happen with lights, it is almost always bad grounds at fault.
More information should get you more answers.

I have the same problem with the exact set up. I haven't tried to fix yet but my thoughs are that our cars have a ton of EMF. Ignition and charging systems. Ground being good because the lights blink normal with car not running. I want to try a condenser ie capacitor at the flash can unit. All I will try is a old points condenser and see if it works. Any othe thoughts controlling EMF would be appriciated.

Just in case there is a question as to what EMF is, here goes..... I say this because I haven't heard that term used since high school physics back when Elvis was king.

Electromotive force is defined as the electric pressure that makes a current flow in a circuit.
An example of electromotive force is voltage generated by a battery.
EMF is measured in VOLTS.

Thanks, 19Fordy , I think I have a over voltage problem at the electronic flasher when the alt is running.I all so have a pertronic ign and 12 volt alt. this may have something to do with it. When I rev the motor up the LED lights go faster then solid. Thanks,

I had a cheap electronic LED flasher on my model A. It never worked well and only lasted a few months. I went to an auto parts store and in the electrical catalog I found aheavy duty large 12V truck flasher. It is a small cube and will flash any type of load and I do not think it is voltage sensitive. It was expensive $20 or so but it has worked for several years.

I have fixed my LED flasher problem. I ordered a FL3- red: 3 pin red American Flasher from Superbrightleds.com plugged it in every led light flashed right. Don't buy anything made in China. The flasher from Bob Drake will not work or anything else he selled made in China.
