Generac genset will start but wont run

 


We are off-grid in Captian Cook, Hawaii.
Am looking to bounce this off you folks for ideas.
Its a generac 10kw model 09112-1 or 4w118
This generator feeds a trace 3624 which feeds my 8 6v deepcells.
On a good day we get 25 amps from the panels.

to see the problem, watch these two phone videos:







A second genset is working as a temporary backup, and as another
project, it will be automatically driven by a morningstar relay driver
(its in the mail now, cant wait).

 

Visited there, the roads are insane, but I guess you can do that when
you don't have snow...

Anyway, without looking at any videos (sorry, I have limited bandwidth
and time), I'd suspect an oil pressure problem, or an oil pressure
switch problem. Then again, it could be thermal, or any other safety
shutdown which is bypassed while cranking over. You figure out which
ones apply to you, and what bypassing them involves, and see which one
makes it run when bypassed. Then you figure out if the condition
actually applies (ie, no oil pressure), or if the sensor is broken.
Either fix the problem a working sensor is sensing, or replace the
sensor.

Or the ignition ballast resistor if it uses an
ignition coil. It sure sounds like this.

Yes, I've seen (and experienced) this exact symptom / cause on a car
with contact point ignition.  The starter bypasses the resistor /
ignition circuit, so the car would start and, once the ignition switch
is released, die.

 

Many of us are on dialup and have no hope of downloading videos so we
need a better ascii description
