so what I thought was a simple bilge pump swap has become more interesting. I have an 89 380 and as typical the wiring was onesplive after another. so while I was working om it I thought I would get back to the original. OK so I have a black (ground I assume) and two thick brown wires (one auto and one manual) and one thin wire. (No idea) I have zero power on anything. the breaker is on and I get power to one terminal on the switch at the helm (also brown wires) The other two switches for the mid and aft work fine both in auto and manual and all three switches have the same output. Odd in all 3 instances with the switch in either position do I get power of the brown terminal. So is the power I am reading the power in? With the 2 pole switch 3 blade connector all that is connected is two brown and black ground. So how is this setup? auto power from the Battery directly and bypassed with the switch? without the third wire I don't see this working all from the switch. bottom line is where to start looking for power? My initial thought is a bad ground? Help and thanks
