Wimpy Wiper Washer spray (Page 1/1)

I have a new Washer motor/Pump, but very sorry excuse for spray.
With the engine off, the fluid just dribbles out of the squirters, while with the engine running, I get spray up the windshield only about half way.

Going a step further, I see I have only 7.5 volts at the pump with the engine off and around 10 volts with the engine running.

Battery is fully charged, car starts fine, no other voltage problems.

Anyone know what is the expected voltage at the pump, and if there is a splice or connector in the Pump circuit I could check for corrosion? Suggestions to improve my spray ?? Seems like I need to get the voltage at the pump back up to 12-13 volts to return the spray to the days of old.

I like firing off some 'chaff' when I have guys tailgating me.

The washer pump needs 12vdc. What year & engine do you have? I will check the appropriate wiring diagram.

Often low volts at 1 thing or three is only a symptom for iffy grounds etc anywhere in a car.
See my Cave, Electric Motors etc.
