blue sea ACR start isolation necessary? If yes, start wire location?

Hi gang,

Do you forsee the need for the start isolation optional feature of the ACR?

On the manual its isolation #1 (brown wire).

If you did install it where's the easiest location to tap into the start wire? Having a hell of time locating the wire. Novice here btw.

TIA and cheers!

My vote would be yes.

If you had a previous build with SMB that used the Surepower 1315, they probably already have a wire that is attached to that circuit. They did change it up at times so you will need to check that it has 12 volts only when the key is in start. (Note: They have been know to wire it to the line that is Hot in both start & run)

If not, or your wire is wrong. My 2004 Books say that the start circuit on the key switch connector C250, the switched power to the start solenoid is WH/PK. It should go to your fuse block F2.33 (Starter Relay Diesel), Digital Transmission Range Sensor (Except Diesel). Also F2.27 is for Radio. (Start Cut Out), this goes to PIN 3 (RD/BK) on the Radio Connector.

Hi Greg,

You came to the rescue.

I did notice a single wire before when I yanked my Surepower out. I'll have another look at it.
Cheers!

Central Junction Box (fuse box) is under drivers side footwell.


see Fuse location F2.27 or F2.33. You can use a fuse tap such as https://www.amazon.com/Lumision-SHIP...ords=fuse+taps Link is for a mini fuse which I beleive is what is in the box, but check for sure.

Hi Greg. Will definitely buy you a beer should we meet.

The mini tap will definitely make life easier. Thanks.
