Wiper Motor

Removed the wiper motor today, cleaned it, put in new bushes, etc.

I then hooked it up to its wires in the car to make sure it worked; no problem.

I then installed it and guess what? /bcforum/images/%%GRAEMLIN_URL%%/cryin.gif

It blew the fuse everytime I pulled the wiper switch.

Removed the thing, retested it, and it worked fine without blowing a fuse.

I've run out of fuses now and I'm baffled.

Why is the fuse blowing as soon as it's completely installed?

I'm greatful in hearing your suggestions /bcforum/images/%%GRAEMLIN_URL%%/bow.gif
 
Sounds like you have too much friction in the tubes and/or wheelbox area (where the wiper arms attach). The grease may be hard and dry in the tubes or gears causing the motor to bog down and fuses to blow. Anyway .. just a guess.

Cheers,
John
 
Hi Higgins,
One thing comes to mind. When you bench tested or hooked the wires up to test in the car, was the motor housing grounded? The dash switch is a ground interrupt, not a power lead. My guess is the green(hot) wire and the green/black(ground) have been connected backwards.
