I spoke with Todd Wagner from TideWater Z. He said the pump has continuous power and the ground is switched. We looked at the simple push button switch. Looks like two copper strips are grounded to the steering column when you press the button. I already think I know what my problem is.... - I could not get the turn signal switch and multi-function switch to tighten against the steering column. They seemed to have a little play. - I cut a piece of closed cell foam to act like a spacer or gasket so I could tighten the switches against the steering column. - I bet the foam blocks the push button, copper strips from grounding against the steering column. I am traveling this week. I will post another response when I get home. -rick

Mike, E, thanks for the help. The ~14v at the plug was with the car running. I will check the switch. I pulled a switch from a '72 from a junk yard a few months ago so I might do a quick swap to see if the problem remains. I will post an update after my troubleshooting. -rick

The two wires that power the windshield washer pump in my 1972 240Z are always hot. Voltmeter reads about 14v. Pressing the washer button on the multi-function switch doesn't change the voltage. Suggestions on the source of the problem? - Bad multi-function switch? - Short in the wire harness? - Is 14v the correct voltage to power the pump? -rick IZCC #7509 1972 240Z 1982 280ZX
