Ziller has the board listed that you need, I'll bet they have it in stock since it's a common item P/N 0D86150SRV - $259.00, If you call them Monday morning they'll have it in the mail right away.

OK!  Woke up in the middle of the night, when the thing roared to life on it's own ... something it hasn't done in over a year and a half. at least, since it was "serviced" - checked, the neighbors porch lights were out ...  It ran for around 40 minutes, then shut itself off ... going out this morning to unplug the little float charger and see if the nearly battery goes dead after a bit, also, waiting to see if it cycles on its own ... which should be today or tomorrow, honestly, forgot which one I set it on, when out there testing things, but, hopefully, which ever one of those fails to work, should help decide what board needs to be replaced ... Maybe wiggling or resetting every contact, while testing things did something good?  I was NOT looking forward to climbing the inside or the outside stairs to make the thing work again this winter.

OK, the generator did it's thing, the other day, ran it's auto cycle ... "It's alive" (so, this is two things it hasn't done on it's own since that "service" - well three, because it kept the auto cycle setting, normally, when I would go out and look at it, all of the lights would be red ... and I would reset it). Am I correct in assuming that it only charges the battery, during that cycle?  Which would mean that if the newer ( year and a half old ) battery, goes dead ... that the charging circuit board is not working ? Or, is the battery powering a circuit which might drain it faster?  Have the little float charger unplugged, so if I don't lose power during the little snowstorm we are expecting this week .... the battery will have been sitting for a week with the next auto cycle. Time will tell?

Forgive me I have not had time to be on the forum. You are using the wrong part number. You want  0D86150SRV. I confirmed on GenService it is a fit for your generator. We have it in stock.

nfw01, the battery is being charged at all times if the system is factory stock. When at rest the charger is energized by 240 volts from the transfer switch, when the generator is running the charger is energized by a winding in the alternator at 240 volts. The exception being when utility power fails and the generator is not yet running - no charging supply voltage available from either source.

OK, for what it is worth, system cycled on its own, again this week, thats two weeks in a row ... (without the trickle charger keeping the battery up ...) went back and tested the ATS and the control box, have the proper 12v on all legs, inside and out ... it didn't claim it overcranked, and didn't lose its cycle timer settings ... I think I want to let things go on a few weeks to see if  the battery fails, or?  hoping that might narrow it down to one board or the other, but, I am decided that next spring, with my refund, I buy all the replacement parts for this thing I can afford ... already planning to "drop off" the new one, at my friends place, an early "Merry Christmas" because they really need it ... my place is at least next to the road, if I set it on fire, someone will come and see why,  theirs, is more than 1000' back in the woods, and even their wood furnace doesn't work without electricity ... put the silly thing on my trailer with the loader, before I took off the bucket and tried to fit on the old Erskine 540 snow thrower (which I got mounted, but could not get the splines of the power head to  line up to the PTO) ... What I could NOT do, is get the hex bolts on the cover of that new generator to all go in, any three, yes, but not all four - and the silly thing is still mounted firmly to its shipping pallet, so it should still be square and true (just awkward and annoying apparently) Will let everyone know how it goes again next week.

You can check if the on board charger works without waiting to see if it dies. While in standby mode with nothing going on take a reading at the battery. Not sure of the exact voltage to look for but it'll be up in the high 13. something or 14 can't remember. Others will chime in here but the battery in good condition not on the charger will be somewhere in the low 12 range.

Good to know ... didn't actually see this till I logged in to say it just started, for the third week, on it's own ... and is cycling now as I type ... I will try testing it later, after it has set for a while, likely tomorrow ... Thanks, nfw.

If the internal charger is powered and working, you should be seeing something around 13.5 to 13.8 volts at the nominal "12 volt" terminals. If indeed it's closer to 12 volts you have a problem.

Ok, so ... every time I have tested it, the voltage at the ATS panel is lower, first 15v (that was with the little float charger) then 13.4 then 12 now 11.8 my guess is that without the little float charger, nothing is being charged ... question is, how do I KNOW, which board isn't working - the charging one, or the controlling one ...  -  right after I had let it be "serviced" it went thru something like this ... ran for a few weeks, then wouldn't do anything on its own, for two years - without my having to find a way to get out there and manually start it, even though the battery was being kept charged ... then, after all the circuit testing and fiddling with the connections, it suddenly started when the power went out, and cycling on its own  ...  I clearly won't start on it's own now, so I will hobble out and reconnect the charger. But, which one should I replace? or, replace first? can they be tested for faults, thanks, nfw.

Yup.  With that little "float" battery charger reconnected, the voltage is back up, and it cycled again, on it's own ... good thing, had more than enough ice, then snow too. Wish there was a definitive way to narrow things down without just biting the bullet and spending $600 for two new boards, and $90 for shipping ...
