Hi all,

If I use a jump pack (12V)to bench test my wiper motors, which are 1984 vintage and have a single power connection, am I supposed to go positive to the connection and ground to anywhere on the motor's steel casing?

I've got a three motor set up, with three separate toggles, and none work. The fuse(s) and line(s) in are ok so I took them down to bench test them.

Thanks

James

go striaght to the motor wire. If it works then you know the issue is inline somewhere and not the motor. If its in the wiring then a multimeter should help you find where the problem is.

If it is a one wire connection then positive to the terminal and negative to the body. In such a case the windshield frame would act as ground so look for the ground connection to the windshield frame and ensure there is continuity.

most times you can take those apart and sand the armature put some greese on the bushing and they will live again.. i usuaul ground the mounting ear to test but i usually clean them up first then test them. it only takes a minute or two to lightly sand the armature and fight with the brushes

opps but i agree test for power at the motor.

Thanks for the help to all. Corroded ground(s), a little clean and sand and all three work great.

Boat's been on land for 2 seasons while I restored it in my spare time. Trying to knock out a few more items before the tractor trailer trip to the travel lift next Thursday the 16th. This forum's been a big help.

+++ on cleaning the armature, most motors respond to what I call TLC (tender loving care)
