[JB] [JB11] Newmar Start Guard

[hubesail]

Relates to another post about your post on "Installing power circuits for marine electronics". I am going to fully implement your recommendations with proper sized breakers, a fuse block, and add in the Newmar Start Guard for power conditioning.

On the wiring diagram for the Start Guard (not your product I know) it calls for a sensor lead down to the starter solenoid and says in the manual "Whenever 12 VDC is sensed on either of the STARTER terminals, the internal relay will close and bring the internal battery on-line to provide supplemental voltage to the sensitive electronic device. When the starter is disengaged and there is no longer 12 VDC present on either terminal, the relay will open, disengaging the battery."

In your post you say that power conditioning is needed for isolating the electronics from engine starting and other high current equipment like Thrusters, winches, pumps, macerators, etc.

So, the question is whether the Newmar Start Guard really provides that electrical isolation for other than engine starting. I'm just not sure from reading their documentation.

Any help will be appreciated.

Thanks, Hube Hopkins
