Just curious, why are you running white wire?
Typical color code is;
Main, or Battery = Red
Ground = Black
Start= Yellow
Start safety = Yellow w/Red Tracer
Ignition = Purple
Fuel Sender = Pink
Oil Sender = Blue
Water Temp = Tan
Alternator Excite = Red w/Blue Tracer
The reason I'm wondering is besause if a regular wiring schematic is used it makes troubleshooting easier.
You can also get the above colors at NAPA, they even stock the Marine Spec. wire through the Balkamp line.
Again, just curious if I am missing something.
