I have a PathMaker model 100-3 combiner that has lost
its brains. I've read the stories from the Manta
group owners that report continuing problems with these units, so I'm not real enthusiastic about spending money
to replace the logic board. I do have the remote
control switch, but it will still not combine the banks as it should when I put that switch to manual ON. The only thing the unit does for me is show the yellow light when the house bank voltage drops below the threshold setting.
I can combine all banks by connecting a jumper from a battery
B+ voltage to the solenoid actuating circuit (purple wire). As it sits now, only the house bank gets charged unless I jumper the solenoids this way - and that explains why my starting batteries were flat recently.
Anyway, I plan to just hard-wire a toggle switch to activate the combiner solenoids instead of replacing the "brain" that should do this automagically. I have a lighted (LED) switch so that I shouldn't forget and leave the banks combined.
Anyone see any problems in doing this? I'm just replacing the unit's brain with my own.... in the hope that I'll be smarter than a 5th grader...
