Well gang....Over the weekend, I spent maybe 16 hours under the dash of this old 1990 Parker MV trying to unravel 17 years of wiring abuse.....With some success I might add - but sadly, not the progress I'd hoped for Previous owner only added new wires - never removed the old ones. I've got more dead ends than Washington DC.
I do have 2 questions some of you faithful could help me with....On the boat transom, there is a Pisco (sp) switch (two positions - on & off) under the port seat that, once placed in the "on" position, causes a fuse block under the dash to get power and things such as GPS, VHF, AM/FM, cigarette lighter and misc other "stuff" can be used.
Under the starboard seat is another switch with 1,2, ALL & OFF.....Now I know that is the switch that directs power to the motor (one, two or both batteries).....I also thought it would route power to the main switch panel on the dash - nav lights, wipers, horn, raw water, cabin lights, etc......
Well, not on this tug - the toggle panel stays hot all the time. Is that the original design or am I right and it should be dead when the switch on the starboard transom is in the off position?
Second question. When the AM/FM radio is on and/or the VHF, all is as expected. Turn on the GPS and that's the end of listening to either radio comfortably - tons of static Called Garman and they said most likely a poor ground on the GPS....Well, part of that 16 hours under the dash found the GPS wires and I can tell you, there's nothing wrong with the ground or hot wire connections. Removed them, polished them and verified 12.3 volts and good ground. Any thoughts????
Thanks Gang,
