Archived Block heater not working??????

[dieseldon02]

Please help, yesterday I had pluged the truck in all day, went to leave for work, and it seems like the block heater wasnt working. Is there any thing I can look for to see if in fact its not working? Fuse, wires... I"m not even sure where it is located. Any help will be appreciated. Thanks, Don.

Don, an easy check would be to take a volt/ohm meter and take an ohm reading right at the male plug end. This would tell if the heater was "open" or possibly shorted. It's a place to start. I "think" on an 02 the heater is just behind the oil filter, it's easier to "see" from below. It's possible the circuit from the house was dead? I plugged my extension into a GFI in the garage and forgot to check the trip switch, the next morning I thought the same as you until I looked a bit further into things. If all is OK with power supply, try the ohm meter on the plug first to see what's going on.

Thanks for the info Joe, the cord going to the heater was dead, ordered one from Cummins, hopfully it will be here tomorrow. Thanks, Don.
