None of my factory gagues are working, ive checked fuses and all of them are good, i pulled the cluster and checked the connection and everything looks good, someone put aftermarket gauges in and they work but the cluster is driving me nuts!

 

They probably took the sensors out for the temp and oil when they installed the aftermarket gauges. And the fuel sending unit is probably bad for the fuel gauge.

All you have to do is find the wires that goes to the sending units, and with the key in run, engine off, touch the wire to ground and watch the gauge. It should swing full scale to one end or the other. Then take it off ground and it will swing the opposite way. If it does this, the gauge and the wiring are good, the sending unit is bad or missing.

Should be a wire hanging around down near the oil filter on the 302/351w engine. Somewhere on top of the engine should be another wire hanging around for the temp sensor. The sending unit for the fuel is plugged in on top of the fuel tank.

 

thanks for the reply bud, i have a 300i6 id love to atleast have a fuel gauge

 

Have you verified that the cluster is getting power?

I was having an intermittent dead cluster issue which turns out to be a wonky ignition switch. Turns out my return spring is weak, and sometimes, especially when its cold, the key doesn't bounce back all the way from the "start" position, kind of gets stuck between "start" and "run". In this position, none of the accessories get power, no radio, no gauges, no turn signals, etc.

It's an idea to check if really the entire cluster is dead.

 

Go back to the tank and check it out.

 

Thanks fellas, sorry for the late reply. Things have been hectic, havent got a chance to check everything. Out

 

Well i checked the power for the sending unit and it pulses, the factory sensors have been removed so thats why the cluster is dead. So the sending unit is probably bad?
