Farkin Washer Pump...

[Kip]

OK, help me out with DC circuit theory...

Washer pump did not work, lines clear, so I metered the socket to pump, got 12VDC.

(note, do not place multimeter on windshield for ease of view, as wipers operate, they turn into a working siege engine model, and send multimeter skyward)

So, circuit good...bought new pump, installed, did not work.
Switched out wiper relay mod, still no go. Check terminals in fuse box per Bentley, all read correct.

SO, I think I am getting good voltage, but no amperage to run pump. Any ideas?

Bad ground? Did you use the ground in the pump harness or another ground point?

[Kip]

Duh...ground?

I just measured between to two pins in the connector. And did the Bently checks. Don't have the book in front of me.

Is there a ground I should look for? Where? I guess I should check resistance from these terminals to ground.

Polarity is correct, pump is good, I was leaning to a short to ground, but I would have read less than 12VDC, huh? Need to meter from fusebox terminal to connector ends.

That's fine.

If you are measuring 12V then I would say that the pump isn't ok. Have you tried running the pump of a plain 12v power source to see if it actually runs?

[Kip]

Pump is verified on a 12vdc power source, and is brand new. Switched out relay control mod onto the other 325, and it worked fine. Wipers function great, just no squirt.

I'm thinking that there is a short to ground, and even tho I am seeing 12VDC at connector, most of amperage is going to chassis somewhere.

E=IxR, P=I/E, it is all a faded memory....

All I know is:

Switch (stalk) when actuated sends voltage to pump.
Voltage and ground checks at fusebox are per specs.
Pump is good.

I'm no Edison but I think if you had a short then you'd be getting a lot less than 12v.

Maybe the connectors aren't making a good contact with the the pump connectors.
