at the NCOC auto class I take, our class was split into 2 groups, my group is doing a series circut, in which we built a realistic series circut, using the door from a junker '92 Buick Century ( a crash test car actully, car only had 300 miles on it but it's 1 of our parts cars ). we took the rear drivers door off and we'v got a stand built for it, and we started wiring it. we have the main fuse box from a '92 Chevy Lumina now. we were going to just use a fuse, but I heard my teacher mumbeling to himself, for the second stage of the project he was going to throw us a fast ball, and as I had the window wiring diagram out for the car, he noticed that there was no relay in the circut, and was supprised by that. so me and a couple others figured we would stay 1 step ahead of the teacher and run a relay, so were running 1 of the 5 pin relays that was in the fuse box. I wired it, but it dosn't work. I Ohm checked the relay and pin 30 has continuity to 87A all the time, I ran a wire from 87A to the correct power wire in the door, and grounded pin 30, I know this is wrong now because I found out pin 30 is high current output. I knew that 85 goes to 86 and is the low current side of the relay. but just to make shure as it has to work tomorrow, I ground 86 and add power and a switch to 85, then run constant power from 87 to 30 right? were just going to use an on/ off switch to operate the relay.
