Wiper motor no go
Gentlemen,
I have a question and I believe I know the answer but I am so frustrated that I just want confirmation. On Oct 11, 2021 I bought a new wiper motor/pump assembly from APE. It was a ROYAL PITA to attach (that was a separate post) and now that I have all the harnesses installed, it does not work. My switch is making good ground. I have 12V power at the middle terminal on the motor and the two black wires make good ground when the switch is alternately on high or low. That's what it is supposed to do, right? I ran jumpers from the battery terminals to the motor - still no life. So, in my non-electrically astute mind it has to be a bad motor, right? Looks like I'll be buying a new motor. I can't expect APE to accept a return after all this time, even though the motor has never run. I did not think to bench test a brand new motor. Anything else I should do to further test, or any other easily remedied fixes I should try? Also, this is a 1970 GTO convertible with concealed wipers. But you probably knew that. Here is a photo of the terminals (I don't know why I am posting this photo) and one of Oscar the GTO puppy - Supervisor of Restoration |
