View Full Version : Amp pull of wipers

A 1955 President State, what amperage does the wiper motor pull? I want to drop the voltage from 12 V to 6 V. I'm sure the motor is 6 V and PO has no voltage reducer . I have a resistor that is 1.5 ohms, directions say this will drop the voltage to 6 V but for 4 Amps ( not above or below 4 amps ). There are several ways to hook resistorS up for varing amp draws at 6 V. I tried the 4 amp set up and the resistor gets hot enough the burn my hand when the wiper is on.

It'll burn your hand regardless, that's how it wastes the voltage drop. Try measuring the voltage at the wiper in operation at the different settings. (look for 6-8 volts)

Why not just put a 12V motor on there??? Any 56 thru '60 wiper motor will fit right on there!:D
