Wiper motor bench test

[Michael G.]

Finally getting around to bench testing my '66 wiper motor however nutt'n happens after hooking it up. The procedure I'm using is:

• Ground (12-) the case
• Positive (12+) to middle terminal
• Ground (12-) to inside terminal (high speed). Ground (12-) to outside terminal for low speed. However doesn't work on high speed.

Nothing. Am I missing something here?

Restorer David Gieske who did work has passed away . May need to source outside help....any suggestions there?

Ground the terminal on the ww motor closest to the front of the car. That is high speed. That terminal and the one closest to the firewall is low speed. Center is always +12.

If that don't work. PUNT!

Appears I may need additional help.

After making the connections with 12+ in the middle then grounding the outside terminal motor runs appearing to be low speed which is not right. Jumping the ground to back terminal changes nothing. Continues to run at same speed which as stated appears to be low speed .
