My thermostat arrived today Mon. I will fit it tomorrow and see the result. I have 2 Cadillacs and a Chevy van, the heaters are hot enough to poach eggs. Yank vehicles are never poor heaters. I hope this solves the Voyager problem.
BatteryMOD ButtonMOD Changing the 33K Ω @ 1/2 watt to 22K Ω @ 1/2 watt keeps it under the 4.6[ish] [although I'm sure it would be safe a little higher]. I did get the extra .3's @ 14.4+ I was aiming for. This will better recover the winter loss more quickly. Of course in the summer the ALT output will be limited by the lower battery replenishment needs.
