Boat Wiring Guys,
I need your help with a 1997 Nitro 640 LX fishing boat that I just purchased.
When I put the red/green navigation light into the plug in base at the bow, it doesn't come on, but causes one of my gauge lights to light up and stay on.
Any thoughts on where this might be going wrong?
The ground wire for the dash panel area is no longer connected. Because of this, the dash is grounding through the filament in the red/green light.
Run a test ground wire from the battery negative to any ground at the helm (maybe a gauge) to confirm.
Hope this helps
Thanks for the quick response,
You were right about the ground wire. We found and fixed that, but we have another problem now.
There is a large wire with a plug that goes into the motor that there is apparently a short in.....when we turn the ignition on, it will not do anything sometimes until you move that large wire around.
What is that wire called that plugs into the motor and apparently goes to the switch as well?
We need to figure out what to get to replace it.
It sounds like it is your main engine harness plug.
Most of those are modular and can be taken apart. This means that you may be able to just replace some terminals instead of replacing the harness.
