Author Topic:   Blue Sea ACR connection question

I am adding a Blue Sea Dual Circuit System with ACR as I rewire my 1983 Montauk. I am told to connect at the ignition switch to a line that is positive only when cranking. The engine is a new Yamaha F90 4 Stroke. My switch wire choices are Red, Blue, Yellow (x2) White, Black (x2) and Brown. Your insight is greatly appreciated!

The wiring code is in the reference section:

If I splice into the brown wire will I be on the right track?

Thanks again for the help!

Is this what you want to do? If so yes splice into the brown wire going from switch to motor.

From BSS:
To enable start isolation:
• Connect a wire from the quick connect lockout terminal marked SI (starting isolation) to the terminal or wire running from the start key switch to the starter solenoid.
Make this connection through an in-line fuse of 1 to 10 Amps. This connection can be made at the start key switch or at the starter solenoid, but must be to the line that is positive only when cranking. Connection to a line that is positive while the engine is normally running will prevent the charging relay from working properly.

Thanks so much! I have learned a ton from all of you over the past four months!

The folks at Blue Sea have been very helpful with my rewiring projects. Erin Morey at Blue Sea recommended the following two on-line articles on their web site:
http://bluesea.com/viewresource/1366
http://bluesea.com/viewresource/1388

The first is a good overview of the ACR function, and the second gives some installation specifics for the ADD A BATTERY, which uses the SI ACR. Neither of these may be an exact fit for your situation, but they may provide some food for thought.

I installed the same Blue Seas switch/ACR system several months ago when I installed a new Blue Seas fuse panel. One suggestion is to extend the combine indicator light which is on the ACR up to the console dash via the terminal on the ACR unit, I believe it's marked LED if I remember correctly. I used a Blue 10mm and it works very well even in bright sunlight. These can be purchased at electronics parts stores for literally pennies a piece. If you're not comfortable with soldering on a couple of wires, Blue Seas also makes a ready to mount unit that will work as well. I really like the Blue Seas ACR. It helps keep my trolling motor battery (battery #2) charged while fishing.
