[RE-wrenches] Magnum AGS with Kohler RES 8.5

[David Palumbo]

Hi boB,

The Kohler RES is is a very simple 2 wire start as are all of the Kohler's
that I know of. These Kohler's have worked very easily with OutBack and
Trace inverters over the years fro remote automatic start/stop control.

The problem is in getting the Magnum AGS module 12v power when the generator
is running so that the AGS knows when the gen is operating. This particular
model (RES) Kohler does not have a place that we can find this 12v power. It
would be easier for us to use generator 120VAC output power for the AGS's
run signal.

I have hooked up a number of OutBack, and also old Trace SW systems, and we
never had this problem of having to bring 12volt power from a remote
generator back to the inverter for generator control purposes.

Best,

Dave

  Hi David.

  Gary Baxter says he apologizes for not having that exact wiring diagram
for the Kohler RES generator
  and the answer you got over the phone.   (we gotta get him on this list
too soon)

  Magnum Energy does rely somewhat on customers to help with different
generator wiring if they have
  information that we don't have.

       If you or anyone else has wiring diagrams for generators that we do
not have on our site,
  please email or let us know about it and we will try to get added to that
list also which will help everybody.

  We do have quite a few on there now though at
http://www.magnumenergy.com/GenWiringDiagrams.htm

  Also, if you find a wiring diagram on OutBack's web site for this
particular generator, maybe you
  could post a link ??

  If this is a 3 wire hookup, you may have to check with one of the other 3
wire gen start manufacturers like Atkinson.

  There certainly are a LOT of generators out there with their particular
wiring needs.  It would be difficult (tree wise) to
  print every generator wiring  that we even DO have and include it with the
manual.

  Maybe  a CD ??  That'd work.

  Thanks,
  boB

Wrenchsters,

We have a new 3.4kW PV off grid installation that includes a Magnum ME-AGS
Auto Gen Start module, Magnum ME-RC50 Remote Control, MS4448AE inverter and
a Kohler 8.5 RES lp gas generator for automatic backup battery charging (16
L-16G's).

We have successfully used a Magnum AGS control Magnum with an older 3 wire
start Onan although it took some time in finding 12 volts that is only on
when the gen is running (typically the hour meter power).

With the Kohler 8.5 RES there is no hour meter or other obvious location in
the generator for 12v power that is only on when the gen is running. We
called Magnum from the site only to be told that all of the information we
needed was on line. The man was still un-helpful when we told him that we
were on a remote installation with no internet access. Now I'm back at the
shop and on the web. On the Magnum web site I see a hook-up diagram for
their AGS with a Kohler RMY series generator. Nothing for a RES series.

Next time we'll go back to OutBack.

Any help that the wrench community can lend on working this situation out
would be appreciated.
