#87105 07/20/2003 1:21 PM | Joined: Jul 2003 Posts: 6 Junior Member | Junior Member Joined: Jul 2003 Posts: 6 | I have a 1949 chevy 6400 that has been sitting for a while. When I hook up the battery to turn the engine over, the steel tube for the oil pressure sending unit gets very hot. Could the engine be trying to ground through this tube? I know I will have to rewire it, but I want to hear it run. Any help will be appreciated. | | |

Check for frayed wires contacting the tube. The suggestion about checking for a good cab ground is appropriate. Somehow, the dash lights and such in the cab may be returning to ground through the tube.
The funny part about electrons is that they will find a path, any path, even ones they are not supposed to use, and in the absence of a path, they will leap across gaps. Of course, in the case of spark plugs, this is good.
I apologize for sounding so insultingly simplistic. I don't mean to be talking down to anyone.

I'd install an additional ground from the battery to the engine block, leaving the old one in place. Then check to see if it gets hot with that ground in place. Mike | | |
