Please forgive me if this has already been addressed else where on the forum. I recently just purchased a 1999 hurricane 198 in which the fuel gauge pegs 'empty' when you turn the key on. My steps thus far:
Power is getting to gauge and sending unit
Using a test light, with the ground of the light attached to the battery ground and touching both the Red and Black wires, both show a completed circuit.
tested the resistance between the red wire and grounding (with the black wire detached) and got a reading of 45-50 (the tank is practically full)
With all wires connected, and using the test light. both connections have a completed circuit with the ground light attached to the batt negative.
If I ground the fuel sending unit directly to the battery, the gauge reads 'full'
what baffles me is with the green/black wire when disconnected and using a VM, is showing 12+ volts
Is this correct? I thought this was a ground/bonding wire that, when the VM is connected to the negative of the battery and connected to the green/black wire shouldn't show a reading.
How do I make sure the unit is wired correctly before I buy a new sending unit? thanks for any help!!
