I have a gas powered 6.5 KW Kohler generator Model 6.5CZ that blows
the 10 amp input fuse whenever I shut it down from the engine mounted
or remote kill switches. It then won't restart until I install a new
fuse. Does anyone have any idea what would be causing this? The unit
starts & runs fine, and for now, I stop it by removing the fuse and
then replace it once it is shut down.

There is a second fuse, but this goes to the battery charging system
and seems to be unaffected by the stopping sequence. I have this
posted to a couple of boating & RV groups so I hope someone can help
me on it. Please feel free to respond to my email directly if you're
reluctant to respond to the group.

Thanks in advance.

Obviously the "kill" switch energizes a relay or solenoid to either
interrupt ignition or fuel. I am not familiar with gas generators but on a
diesel, the kill switch usually energizes a fuel supply solenoid. I'd
look to see what that fuse is supplying power to and I suspect whatever it
is ... is bad.

You must disconnect all generator load before shutting it down or you can
damage both the generator or the load. Perhaps there is an automatic
disconnect that is now not functioning. Try manually unplugging all loads,
then shutting down.

Could an improper ground of the controlled component cause the blown
fuse, or would it be more likely that the component itself is gunny
sack?

As an electrical duffer, my other horseback guess might be a short
circuit in the wiring connecting the switches to the controlled shut-
off component. Could the generator be stopping because the fuse is
blown by bad wiring in the control circuit rather, than due to any
reaction to the switch(es)?

Giving the OP's post more thought,

If the generator shuts down ok by *removing* the 10 amp fuse that normally
blows if using one of the kill switches, it suggests that a solenoid or
something is *energized* while running. The kill switches must interrupt
the power to something .... same as removing the fuse.

Therefore, I'd probably be looking for a wiring problem.

What's an "input fuse"?
I may be blowing wind, and I have no experience of this rig,
but a mechanism that comes to mind is this:
the engine slows, the generator volts drop, and the field regulator
boosts the current to hold the output voltage, blowing a field current
fuse.

Thinking it through, I believe the kill switch grounds the voltage
from the coil voltage to the block, so it doesn't reach the spark
plug...before it gets to the spark plug, shorting the voltage between
the coil and the spark plugs, which ceases the spark, and causes

"input" fuse is what it's marked. When the fuse is blown, the starter
won't run. It is only a 10 amp fuse so I don't think the power for
the starter runs THRU the fuse, but the fuse must protect some sort of
contactor or solenoid which closes the circuit for the starter. I
thought there might be something on the toggle switch that is
shorting, but it seems to blow the fuse whether the remote kill switch
or unit mounted switch is used to kill the generator.

I am not an expert and there are others here that may have more exact
knowledge, but I think your starter solenoid is bad.

Fuses have other characteristics than Amps. What type does the owners
manual recommend?
