Title: Wiper motor wiring. Post by: FC Dave on January 13, 2014, 09:31:18 PM I have an electrical question. I have an electric switch in my 58 wagon for the wipers with 2 wires. On the ohm meter it is good. On the wiper motor ( not sure what model) I have 2 tabs for wires. One says Battery, the other, switch. I am wondering if someone could point me in the right direction as far as what goes where. There doesn't seem to be an earth point. Any combination I have done seems to power up the whole wiper motor, casing and all . Are these earthed through the body? Thanks in advance, Dave.

I'll check my old loom tomorrow as I still have it all connected from when I took it out of the car and let you know.

Title: Re: Wiper motor wiring. Post by: mcl1959 on January 14, 2014, 08:51:57 AM For simple single speed motors the circuit goes: battery - wiper motor - switch - earth.
However, once the switch is off the motor stops, hence an additional earth strap is added to allow the wipers to park once the switch is off. Ken Title: Re: Wiper motor wiring. Post by: FC Dave on January 23, 2014, 06:44:42 PM Thankyou, I will give it a go on the weekend.
