I have the feed from the side lights going to terminal number 85 and the ground going to 86, would this be correct?
other than that is there any other way of checking?
Thanks for your help mate
Yes you have the relay coil wired the wrong way around. Non diode relays are polarity insensitive which is why you will see some diagrams (incorrectly) indicating coil should be wired as yours even though this doesn't conform to pin codings. As Roger correctly suggests though the diode, there just to quash the the back (reverse) emf as the coil is de-energised, is now providing a direct short when energised. Hopefully you haven't damaged the diode so just reverse coil connections ensuring ground is connected to 85 and all should be good.
