headbolt issues

You may have to unplug something, as a Diesel pulls more amps than a gasser. I usually unplug the oil pan pad or a battery pad.[COLOR="Silver"]

[/COLOR]The 99 6.5L TD suburban blows the one at work when I first plug it in. If I reset it, it works fine.

I unplugged the trans pad or one of the battery pads and it worked fine. The block heater in the Diesel is a higher amperage than a gasser, plus two battery pads = a lot more draw than a gasser.
