Ok, I just got my salvage project
Phasor P2-13 (Beta Marine
BZ482 clone) engine
installed. It came with a control panel
featuring a tach, oil
temp, voltmeter, etc.
So here's the mystery. When I crank the motor
, all the gauges come on, but then go back off when the key returns to the accessory position.
My first thought, "oh, I have them on the start terminal, instead of the accessory terminal." Wrong. They're on the accessory terminal, and the starter is definitely on its own start terminal.
So I jumpered a cable from always-on power to the accessory terminal. This makes the gauges come to life BUT ONLY when the key is turned to accessory.
That makes no sense to me because if I jumper from always on to the start terminal, it cranks the starter over no matter what position the key is in. I mean, if I'm making the connection outside of the switch, why would the position of the switch matter at all?
I'm really confused. Am I lacking a ground to my control panel wiring
? Why is my accessory switch not getting power if I have the key turned to accessory and the voltmeter grounding to the engine
? Why does accessory power work with the switch when I have the terminal directly jumpered to the always-on power?
