Re: [OMC-Boats] Electrical Syetem 1970 Seasport

Lee,
Thanks so much for the info and the direction to the wiring site.
It appears that I have wiring that falls between the 1968 and 1973
schematics. If I was an electrician I could probably figure it out better,
but I have to struggle to trace and try to figure out what this here little
ole wire does. I replaced all the wires between the starter and assist relay
one at a time because of corrosion and missing insulation. My combination
amp/fuel gauge appears to be inop, so that is why I am trying to trace
wires. The gas gauge reads empty with 7 gals of gas installed. The sender
reads over 100 ohms with the pink wire disconnected ,but I am unsure what
ohms I should be to looking for, or what I should be reading in the pink
wire from sender to gauge.
I have both red and orange heavy gauge wire at the fuel/amp gauge as well as
ground and the pink wire.
I have not removed any wires from the gauge assembly, I am reluctant to
disassemble until I understand it better.

Thanks again for your help
Ted Robinson
Terrebonne, Oregon
