Hi there,
I have recently bought a 1997 bayliner Jazz 175hp. It has the Merc sport jet and seems like a pretty tidy wee boat. its starts and runs beautifully off the key as it should, it has been retrofitted with a electric fuel pump and water seperating fuel filter which was to combat a hard to start issue, its starts instantly.
Before I take it into the water I have to have the bilge pump running, Just something I always insist on with a new boat, when i use the dash mounted switch to turn on the bilge pump the warning beeper sounds, the voltage gauge drops, same thing when I activate the blower. The nav light switch doesn't cause the same problem, but they don't work either. I have removed the panel the switches are mounted in and there are no obviously shorted wires. It does have a old cassette radio that is rusty and I will try to remove it, but I am guessing there is a short somewhere as none of the gauges seem to operate either, fuel goes up to past full, tacho looks to be reasonably recently replaced and doesn't ever move, voltage gauge seeems to operate..
Does anyone have any ideas on where to start, Ive looked at the wires to the bilge and blower and they disappear up under the gunnels and are a different color at the switch panel... visually the blower and bilge pump look ok, there is a separate float switch in the bilge also.
Really would like to get this baby in the water as the motor seems to really purrr.
Thanks in advance
