[VintageLambo] Re: Espada window motor

Well, as I read all these good posts regarding the window drive, I wonder if I should take out the Fiat pullies I just installed last night. Hmmm, they move real smooth, but Delrin and ball bearing sound like a better deal. As I don"t have a lathe, the Delrin would be quite a job, but I can go the Ace hardware and get screen door pullies. I have designed the circuit for the two wire motor exchange, and it"s quite simple. Unfortuantely, I did it in Visio and even as a jpg save, the quality isn"t that good. I"ll figure something out that can go in an html or tiff format. The 4 wire system is dead, stick a fork in it, and go to 2 wire if you get involved. Adding the relays is the key to getting 13.8V to the window motor, and saving the switches too. BTW, do you know what Lambo uses for a limit switch both up and down? Hah! There"s a small silver canister between the motor ground wire and chassis ground, that has a current limited resetting breaker inside. When the motor reaches end of travel, current goes way up momentarily, and the breaker trips, stopping flow to the motor. After 10-15 seconds, the breaker resets, and the window will move again. Oh yeah, that"s disaster for the switch & motor, but it gets the job done.
