I have a 1949 3100 that has been converted to 12v. I believe my gas gage is not working (just dumped 5 gallons of gas in it and the gage didn't move off of "E". I have read in the past to first check the ground on either the sender or gage but I have no idea how to do that. Simple instructions for an electrical dummy would be most appreciated. Thanks
