Tri-Metric programming help
I just installed a tri-metric 2025 in the outback 230rs last night and now need help with the programing values of P1, P2, and P3. The battery that came with the OB is a Crown MAR-500: MCA 550 20 A...

Your TT came with one Group 24 starting battery??? Personally I'd have strong words with my RV dealer and/or Outback for installing the wrong battery... but I digress.
The spec's on the MAR-500 are 550 MCA & 440 CCA, but Crown doesn't list a capacity in Amp-Hours, because that battery was never intended to be cycled or used as a house battery. I would venture a (generous) guess that it's in the neighborhood of 50-55Ah.
As a starting point, I suggest that you use a P3 value of "50"
The P1 and P2 values are going to depend on your charger (converter?) and its charge profile, so more info about this component would be helpful (can you verify the charge voltage with a VOM? If not the brand & model will suffice). Most OEM converters peter-out around 13.6 Volts so I'd use "13.5" as your P1 value. Start with "1" as the P2 value.
These values will get your Trimetric working... No guarantees on "correctly".
Hope this helps.
Cheers
