Just for fun... - ZR-1 Net Registry Forums

Paul Workman · 06-13-2014

I bought a pair of standard seats for Ami's ZR-1 to go in place of the (too narrow for her) 91 sport seats. To adapt the seat back position motors of the standard seats to the sport seat harness required a bit of electrical fabrication involving a double pole, double throw, momentary ON switch was required.

It took a minute of doodling on a scratch pad and was a fun little challenge, if you enjoy that kind of thing as I do. Anybody wanna try it?

Given:

Two switches ganged together, each having a (C) common wiper pole, and each (C) wiper pole is flanked by two contact poles (A & B) for a total of 6 ( 3 +3) poles in all.

Problem: Wire the two switches so that toggling the switch(s) will result in alternating the polarity across the DC motor, depending on which way the switch is toggled.

For clarity:

lets call the terminals of switch 1 = A, C1, and B
lets call the terminals of switch 2 = X, C2, and Y.

So, my project for today will be installing the seats in her Z. Mounting the switch and wiring them into the existing harness will be the more difficult part of the puzzle, I recon.

I have to go to the airport in 10 minutes so my effort will be abbreviated.

1) buy a DPDT rocker switch and wire it like this:

or refer to mechanical logic and build something that inverts (this is where i ran out of time, lol.)

Yup! Mighta known you'd jump on that, Mike! (Not shown are the wiper poles; one goes to (+) and the other is grounded.)

I put the 95 sport seats in mine - and just bolted them on the 90 frames. The original switches work all but the lumbar stuff. I have all the harness, switch panel, and an extra lumbar pump to finish it - just waiting on a buddy of mine who has a vast knowledge of electrical to come down and help me with the harness and stuff. I had it all apart once but didn't have the harness part and my back about killed me from leaning over for hours. So now I have the harness and reinforcements coming...
