Trojan wants to be charged at 14.8 at 77F temp. (the absorption voltage (Vabs) you should have the charger set at.)
The Trimetric P1 would not be set higher than what your charger can do though, or it will never see that P1. The Tri instructions for the 2025 say make P1 just under the charger's Vabs-- don't know about the 2030.
If all you have is a 14.4v converter as the charger, 14.3 is right according to the Tri instructions. Trojan batts won't be happy though.
The breakaway switch is on a positive wire, nothing to do with the neg side and the shunt. The "ground" wire that matters is the one that goes from the battery post neg to the frame.
That has to now go to the inner end of the shunt (it also has to be a fatter wire since it will be taking all the current from the various devices attached to the outer end of the shunt), not to the frame. Now the "ground" wire for the battery uses another wire from the outer end of the shunt to the frame.
