early 260z wiper upgrade MEGA FAIL!!!!

[dawg7]

Hey everyone!....I tried the upgrade using the connections below and a 94 honda motor. It worked but the wipers were going down and parking in the full up postion. That is when I got stupid and switched two wires on the relay. I think it was 85 and 30. anyway now I have nothing. I have the FSM and two manuals but I can't find why I am not getting power at the motor connector or the wiper amp.

I did some basic troubleshooting. First I checked the fuse and it is good. Then I disconnected the negative on battery and did some continuity checks on the combo switch as per FSM, that checked out. Next I checked the continuity on the motor connector. Black to frame ground-good. black to blue/yellow has continuty and so does black to blue/white. I am not sure if that is right. I tried to check power at the wiper amp. I checked every color to every other color wire and didn't get any volts. I am pretty lost right now and feel like the only cure is a beer. Maybe two. Any help is appreciated!

Send a PM to Dave - he is the forum expert on electrical - he made me a plug and play connection for my '72.

did the pm to dave and he gave me the right road to travel......it was the intermittent wiper relay. I kinda fried it.....Dave told me to unplug it. The good news is the 94 honda wiper motor works in lo and hi.

I'm looking forward to my upgrade this winter - a person has to save a few garage projects for snowy weekends! Glad you had an easy fix - thanks to Dave! He has gotten me out of the weeds more than once!
