Faulty fuel gauge
Posted: Wed Jun 25, 2008 9:00 pm
Can anyone help with a fuel gauge problem? My Bongo fuel gauge read nearly full when the tank was brimmed. After using half a tank it read empty. I checked out the forum and hear this a common problem with an apparent fix (ie making sure the black wire on the tank is a good earth and even replacing the standard connector with new spade ends). I changed the connector, checked and found a good earth only to find no reading on the gauge with nearly a full tank of diesel.
I read 6.5 volts across the terminals on the sender and see the same on the back of the instrument cluster ( there is a screw terminal marked 'F-U' - no pun intended - that I have buzzed out right back to the green and yellow wire on the tank sender). Am I missing something here? Please help.
