In the dead of winter a client paid over 2K$ for the PCB. He now has
surge protection on the lines from gen out to the XW. I did not say to
him I told you so, but I am saying here.
Pop a midnite spd on gensets that stay connected all year. If it was
nearby lightning, he was lucky it did not jump the transfer relay into
the inverter electronics!

Me again, Mechanix~ 'Tis the season...for generator problems. Here's
mine:
Kohler model # 8.5RES air cooled propane
Serial number 2159521
Spec number GM29253-GA6
This machine has delivered many off-grid running hours; I suspect a
lightning whack took it down. The main DC battery breaker inexplicably
tripped the same day; inverter etc. are all OK.
How many hours? "A Lot." I can't be more specific b/c the electronic
box with the display is black. The 12v cranking battery seems to have
adequate energy but the black box is truly "blacked out" & doesn't
respond to the red Run button. Three glass fuses near the ADC2100
control box all have continuity.
The physical space in the power shed accommodates this machine housing
but I doubt if any new machine would fit as well.
That "ADC2100" control box in my photo shows several different p/n's on
eBay & I haven't done much more sleuthing. I have only a fuzzy
picture of ours, but squinting at the p/n, ours might be GM28707. Are
they all interchangeable?
The ideal case would be if one of the Wrenches has a "known good"
control box even if it's used or dusty. Clients might be sad
if I persuade them to spend $1k or more for an eBay part then we put it
all together only to find the machine still won't run.
Contact me off-list if you have a part or parts to sell, or a "value
added" parts vendor to suggest. We're in southern Colorado.
If something else may have also been damaged, can I get suggestions as
to the likely culprits? Finally, how far should we go if the clients
really want a new lease on life for this machine? Are there shops that
could do an engine overhaul? Assuming that the generator
windings are OK, are there bearing replacements or other TLC items to
address if we haul it to a shop?
I'm aware that the 2023 stationary propane machines may not have the
"slam it out" longevity that the clients have enjoyed with this one.
Thanks in advance for any suggestions. The Wrench List is the Bomb!
