Cheers for your replies guys! Ian you are right, one of them does have a scortch mark on it, when I wiggled them, the car stalled, when I tried to restart it nothing happened, the starter motor wouldnt even spin.

So I got some jump leads on and it started first time, let it idle for a bit, turned it off, tried to start it again, nothing, dead.

So I jump started it again, kept the revs about ~3kprm for a couple of minutes, let it drop back to idle, switched the lights on to see the temp gauge (it was dark) and the car cut out again and wouldnt restart under its own battery.

Do you reckon the relay has got a short on it and is killing the battery?

I also noticed that the plastic connector that fits onto the pins of the bulb has melted on both sides!!

Help!!
