Please pardon me if I'm in the wrong forum.Just yesterday my Yamaha fuel gauge started showing that I was at "Critical Fuel" by the very last bar blinking...despite having a full fuel tank. Connections underneath the console to the gauge look pristinely clean and are encased in their waterproof, transparent connectors.I have looked at the sender connections at the tank sending unit and they look like they could use a good cleaning. Any suggestion on how to test once I have the connections loose? One is a pink wire going to the sender center terminal and the other is a double "daisy-chained" ground to the tank body and outer portion of the sending unit.The boat is a 2002 Cobia 234 CC. The Fuel gauge is an LCD type that is built into the spedometer.Thanks!
the pink is send, ground the pink to a known good tank ground, you may wish to check your tank grounds as well. once you have determined a good ground,with the key on, connect the pink at the sender to ground. wait 20 seconds or so and the guage should react. if not you may have a bad ground or connection between the pink wire and the guage white wire.the color changes at the meter. if it reacts you most likly have a bad sender.
Yamaha Fuel Gauge ALWAYS blinks low fuel
