Stock GM upfit 77 with combiner across larger isolator. With both batteries fully charged and coach all off and unplugged, the combiner clicks and combines for a few mins ( green LED ON), then clicks and unlatches. This goes on for a few days untill the surface charge is presumably gone. Thought the threshold to combine was up at about 14v. After sitting dormant a week or so I don't hear the relay any more and it's acting like it did when new. Is this the overactive fail mode for these or a normal thing?

John,
I'd suggest you put a voltmeter on the power source side of the combiner.
I suspect you'll find that when the combiner closes, the source voltage
drops below the hold-in voltage (because the newly combined battery is very
low). So, after the 30 sec. (IIRC) hold-in period, the combiner drops out.
The cycle should repeat until the isolated battery is charged to the
hold-in voltage.
Of course, there's a big flaw in that logic: The isolator should act
pretty much the same way; that is, hold the source voltage down until both
batteries reach the same voltage.
Call Yandina and talk to Andina Marie, the inventor of the thing. :-)
Oh yeah, mine quit during my summer trip, so I've got to call her too. :-(

But the combiner has a minimal voltage drop where the isolator drops ~ 0.7 volts. Your batteries should get to a more complete state of charge with use of the combiner.

I don't think that is true. Yes, the diode in the isolator does drop the voltage about .7 volts but the sensor that goes to the alternator from your battery steps the output of the alternator up to compensate. The voltage regulator in the alternator is following the battery voltage.

As far as isolator .7 drop, the alt sense cable feeds back to the alt after the drop so it makes up the difference.... No drop. The combiner is 'bat to bat' and otherwise isolated by the isolator diodes. The combiner never jumps alt to battery.... Only battery to battery

Yep! IF the alternator and sense wire are all doing their "things" as they are supposed to do. BUT!!!!!

I hear mine clicking all the time. Makes me nervous as I wonder what it is doing when there is no charge taking place.

. With the new battery, the combiner stopped it's clicking, etc.
