Hey There,

First off – what a cool site! If you get back to me I’ll be really impressed.

Thought I’d ask before I buy a $20 electrical part I won’t be able to return…

The girlfriend’s Whaler has a three-position push/pull, three terminals. The switch sends 12 volt dc to the anchor light, but less than 3 volt dc to the red and green navigation lights at the bow.

I can swap two terminals and get the inverse..12 volt to the bow, less than 3 volt to the anchor light. Safe to assume it’s the switch?

Will all three way switches be:

• Off
• On post 1
• On post 1 & 2?

It looks like Attwood Marine 7594 should work. I assume I can remove the screws and the existing crimp on receptacles on the wires will slide over the terminals?

Thanks,

John

Hi John,

It sounds like the switch is corroded internally and causing the large voltage drop. You may be able to take it apart and just clean it up.

Not all three-way marine electrical switches will be the same. Some may make contact at each position independently and not a do a “combine”.

I checked Attwood’s schematic on the 7594, it will work great for you application.

This will be a simple boat wiring  job,
