18 Ohms sounds to be about right for the typical resistance of the heating element. Now, check for resistance from each blade of the plug to the ground pin. You should NOT be showing a low value resistance there. That would indicate a short to ground which will trip a breaker. You should have greater than 1-MegOhm (1-Million Ohms).

I believe the block heater draws around 9 Amps, so if you have additional appliances or equipment that are adding electrical draw on the same circuit, it is possible to trip the breaker.

Glad you chimed in PA_FORD_MAN... me being more chemically oriented than electrically, your input came at a good time.

Thanks guys. I did do that, I just dont remember the numbers. Im home now and i dont have a Volt meter. I can check one out tomorrow from school and check it again. Now about the water. yes its snow and my plug was wet untill i wiped it off. But when it blew the first circuit breaker it was dry as a bone out. I did print off the TSB for the glow plug relay if anyone needs it im sure i can copy. Also the procedure on changing the block heater, which is really easy only 5 or 6 steps lol. Hopefully it dont get as cold to night as it was last night!
