block heater not working all the time?? and FASS?
I am in Michigan and it gets cold here once in awhile so I put my 7.3 block heater on a timer and it was working great water gage was almost on normal operating temps when I went to drive it. When I would unplug it from the cord I would see a arc/spark (what ever you want to call it) but the truck would be warm. For some reason half the time now I donít get the arc and the truck is cold as if the heater is just not working. Now I know I have power to the end of the cord since the cords end has a little light in it to tell you it has power. What could that be? a fuse? would think it was a fuse because sometimes it works some times it doesnít. I took a look at the end of the plug (trucks end) and I donít see any cuts/shorts.
Also does anyone run a FASS system in your truck? I'm thinking about getting one. Thanks !
