Are the heaters marked somewhere as to voltage. I don't see anything. New unit I'm going to install on coach.

Is there a spin on air dryer with heater suitable for a GM PD4104?

On our former 4104,we installed an AD9 in area right behind left rear wheels. Carefully cut and hinged lower body panel to access it.

What I did was put the model number into the web browser into the bendix site and up came my model that someone gave me. But i didn't know which one it was 12 or 24 and I needed 24. It was 24 volt.

I need 24volt. Mine is 12 volt. Thought there might be a number actually stamped on heater to verify.

only number is for the whole bottom plate which normally will have the heater in it.

Got the 24 volt heater. Turns out, Bendix color codes the voltage of the heaters. The 12 Volt attachment flange is white, while the 24 volt flange is grey. They note a difference in color in the instructions, but not what the color is.
