I'm running into some strange issues with oil pressure in the dual helm station. The issue seems to have to do with voltage to the oil gauges however the voltage is not low like 11v when the motors are running its up around 14-15v due to the alt. My other boat has the same situation but the gauges work great. There is also a dual set of gauges connected on the FB they are also wacky.
The symptom is with the key on motor off oil PSI reads anywhere from 5-40psi on the oil gauges and kind of moves around on its own. When I start the motors both go to 20 then back down to 10 then up to 20 but don't really change with the rpm's its like they are in sync.
New gauge, new sender, new wire sending, power and ground setup in the engine room isolated from the panel I get 30-40psi at idle. Before I start running all new sending wires and or power wires I thought Id ask if anyone knows what else might be at play here. My other boat only has one motor. I'm thinking something might be going on with the dual set of gauges or its just one bad wire. Problem is the bad wire could be going to FB ext as they are all in parallel.
Any pointers troubleshooting this one would be appreciated. Do the oil psi gauges on your boats move when you turn the key on without starting the engine? If not what might cause this?
