1999 Honda CBR F4
Low fuel light doesn't work, checked the manual (Hayes) says to unplug the 2 wires from the connector and jumper them together, turn the key on and the fuel light should be on. The lights not on. Manual says to replace the printed circuit board inside the guage cluster. 1) sounds expensive, 2) talked to my parts guy at Honda, says he's never heard of that before. So out comes the test light and digital meter, and the wiring diagram from the manual. Battery is good 12.5V, check the ground side, good, checked the power feed from the cluster to the fuel level sensor connector, dimmly lights the test light, meter reads 10.4v (key is on). removed the guage cluster, and checked the resistance of the wires from the cluster connector to the fuel level sesor connector, wires have approx 0.1 -0.2 ohms, (should be ok)
I should mention that everything else in the guage cluster works fine, and from looking at the wiring diagram I have, it seems that the fuel light is integral to the cluster and that power goes through the LED light then to the fuel level sensor, then to ground . The ground has multiple splices to several components so since everything else works I'm thinking that the ground side is ok.
So my question is, did I miss something?? Has anyone else had this problem??? something else I should check??? J1K, Tee Tee, I'm looking to you guys on this one....... It's not a big deal, I just fill up every 150 km's or so, but I would like to have it working......any thoughts??????
