Electrical question. L Mack

Recommended Posts

I have a 1953 L model ladder truck. It has two 12 volt batteries. I had to replace the light flasher which says 24volt on it? I replaced it with one that says 12/24volt and it's not working. Under the hood is original as far as I know.

I assume you replaced the old flasher because it stopped working which begs the question; are you sure it is the flasher? A bad bulb or a break in the circuit will make the lights stay on steady instead of flashing. If anything a 12v should flash very fast if it is the incorrect voltage.

The flasher was acting up. It would be fine and than other times it would take longer to change lights.

There are wires everywhere I am doing one thing at a time retracing and replacing

You can test either flasher with a 12v test light. Wire it up with the test light taking the place of the turn lamp.

if you take the flasher out and test it strait to the battery and prove if its the flasher and not a wiring problem before you go any further might be a good idea
