[RE-wrenches] Honda 3000i low ac output

[Dan Fink]

John; I have dealt with similar issues off-grid with the Honda 3000i
"cubes," one client is in northern BC Canada and the 2 sites are only
accessible by helicopter and float plane. So taking them to a local Honda
PE shop is an expensive proposition!

Before replacing the (super expensive) inverter, try these steps:

   - Unplug all the (numerous) white Molex wire connectors inside one at a
   time, clean the contacts with a wire brush, treat with anti-ox and replug.
   - Check all those wire harnesses for chafing and worn-through insulation.
   - Open the inverter, and check the wiring inside the aluminum case for
   chafing against the case. I believe this is a common failure area.
   - If those don't help, get the 3000i shop manual, it has a very thorough
   troubleshooting section, and:
   - There's an internal 6-pin plug under the throttle control where you
   can read the stator voltage, rotor voltage, etc.

Hopefully it's something simple!

The one Honda 3000i problem I was never able to solve was Magnum MMS
inverters not accepting the AC input from the 3000i. We had similar systems
at 2 camps, and tried both inverters with both generators (had to swap via
heli of course) and it ended up as Magnum saying it's Honda's problem, and
Honda saying it's Magnum's problem.

Good luck!
