Hi there,
I've installed Spal electric windows kit on the back doors using stock electric window buttons on my Fiat Panda. I made molds for buttons out of tweeter covers and wrapped them in leather to match interior. Now, I used (as I think same method) to wire up buttons through set of 2 relays to reverse polarity to drive electric motor here is the diagram of how I wired each door.
The button operates each relay in turn when u press UP or DOWN and LED is on but when I hook clean 12 volt to pin 87, fuse blows as soon as I touch it. Can any one spot where I'm going wrong.
Button 4 pins. 12v pin for LED, Common and 2 pins Up and DOWN of the Common.
I wired in a way so that the motor never had 12v, so that relays operated by ground. But its not working as it keep blowing the fuse each time pin 87 is live. Though maybe repays were faulty so I swapped them but it still does the same. I'm suing standard 12v DC 30/40A relays btw.
Please help as I'm stuck!!! :bang:
