Just swapped the Trimetric over to the camper from the Class C temporary for testing the new battery next week when it comes.
Using the two somewhat beat-up 27s in the camper now, alternator charging via 7-pin proved to be about 14.5 amps in support of the house batts running the inverter running the MW. So I can leave the fuse in Stud 1 and have alternator charging safely under the dreaded 25 amps.
For the voltage drop testing of the new battery and wiring to it, I need a baseline so by using the same wiring as now, the only diff will be the battery change.
700 watt MW is pulling 58.5 amps with the 2000 watt MSW inverter and voltage drop is 0.9 volts (It would be higher amps with PSW of course)
So the new battery is not going to be worked anywhere near its limits, so that is good I guess. Once I get the figures using the Trimetric I can stuff the new battery in its hidey-hole and never see it again, and put the Trimetric back in the MH.
