Have a gauge acting up. (Crusader 454 XLs)
Grounded the sending unit wire on the stbd motor, gauge pegs, grounded the wire on the port motor, gauge goes to zero. Gauge also reads backward (reads 20 psi at idle, when it revs up, reads lower).
Could the wires be reversed on the gauge, causing reversed polarity, or time for a new gauge?
