Trojan T-1275 Trouble
Newbie here. I have a travel trailer that has a Trojan T-1275 battery that is around three years old. The camper spends most of it's time in a pole barn hooked up to a couple of 100 watt solar pan...

I have posted before about this one that is adjustable from 13 to 16.5 volts. Works great. Not very costly either! You can get these LKs in various amp "sizes" from 35 to 120 amps.
Powermax LK Series manual
These instructions are not very clear to me.
ADJUSTING FIXED VOLTAGE : The unit is on the three stage charging mode firstly. 1. move the switch A to "Adjust Fixed Voltage", move switch B gently to adjust voltage from 13~16.5V, and get a fixed output voltage. 2. make sure the voltage as 14.6V, move the switch A to " Three stage charging", then the unit back to standard “Three Stage Charging”, run 14.6V almost 0.5 hour, 13.6V almost 12 hours and then to 13.2V. The voltage value of 3 stage charging will be changed with fixed voltage changed when the unit on “Three stage charging”.
Switch A appears in fact to be a switch. Switch B appears to be a small adjustable resistor.
How does changing the "Boost" (Bulk) voltage setting affect the "Normal" (Float) setting ? Also, this charger does NOT have an Equalization mode.
