Another generator problem? Two questions?

[thomas_sorrentino]

We had an un seasonable hot weekend here and I was running the gen.
with all three A/C's on. I have the yanmar with the 12.5kw kohler.
Water temp. was runing slightly below 220 degrees (which I haven't
seen that high before). Since this is my first summer with the coach,
my first question is to the guys with yanmars. What kind of water
temp. do you see on yours when running the gen. fully loaded on a 92
degree day?

While we were in the store for a 1/2 hr or so, came out and the gen.
was off. None of the start switches will do anything, no clicking,
nothing. The fuse is good. With the water temp. cooled down, I
disconnected the hot water shutdown, still no cranking. If I hot wire
the fuel solenoid with a jumper and jump it at the starter the gen.
starts fine, runs and produces voltage. I just started looking at the
schematics for the control box and I'm thinking it might be one of
the relays in there. They're labeled CR, C, 1CR and 2CR. Am I on the
right path here? And would anybody know which one would give me these
symptoms? I'm pushing the limits of my abilities here!
Thanks

Tom:

I have seen the temps go from 190 to about 210 F, perhaps a radiator
cleaning but that is not your problem.

When you push the start switch C relay closes completing a circuit from
12vdc to ground through normally closed contacts of the CR relay. When the
C relay pulls in, it closes a set of C relay contacts to the starter
solenoid. When the starter solenoid pulls, it closes a set of contacts to
the fuel solenoid and supplies a flash voltage to the field. also a set of
contacts close and supplies voltage to the starter motor. As the starter
motor turns over and the gen set starts the starter solenoid opens and
another set of contacts in the start solenoid continues to supply voltage
to keep the fuel solenoid energized.

It sounds like your starter solenoid is faulty. The is the one on top of
the starter motor proper. Check it with a meter, you should have 12 vdc on
the small post, if only 7 vdc on that wire then the coil of the start
solenoid is bad. Remove the small wire to the small post and check the
voltage again to prove it out. If disconnected and you have 12 vdc when the
switch is pushed, will prove the start solenoid being bad.

Safe travels,

Thomas,
I was seeing what I thought were a little high temps around 200 on my
generator. I found a slight leak where the metal overflow stem attaches to the
neck of the resevoir. I ground off a flat side to a washer put over the stem and
soldered the stem to the neck and the washer to the stem and to the tank for
support of the stem. I noticed the tank had a label on it that read not to fill
the tank but half full. I evacuated down to a half tank. I pressure washed the
radiator and fan blades with a soap mixture. My temps now run in the 180 - 185
range.

Ralph,
I will check that tommorrow and let you know. Just to make sure I
understand you correctly, you want me to put the volt meter on the
small terminal of the start motor solenoid and see if 12vdc is there
when I push the start switch?

Yes, to check the coil of the solenoid. You should have 12 vdc showing on
the meter with the wire attached, if you see only about 7vdc then remove
the wire from the terminal and check voltage.

When you push the start switch, with the gen set open so you can hear, you
should hear some clicking in the engine area. What you want to know is if
the fuel solenoid is
pulling
and you should also hear the fuel pump running. If the start solenoid
checks out ok then we go to the 1CR rely. But first things first. I will be
home tomorrow if you want to call, I can walk you through it, step by step.

Ralph,
When I push the start switch, there is no sound, no clicking, no fuel
solenoid pulling in, no fuel pump running--nothing. I will check
voltage on the starter solenoid and let you know.

Tom... I have a 8.0 kabota(89sp)and had gen set problems since I
bought it two years ago. I finnaly took it to a onan dealer here and
had it fixed($300). Problem was the cannon plun on the control box.
The pin that supplied 12 vto glow plugs waqs burnt. They bypassed the
plug with new wires. This plug can cause a lot of gen set problems.

Ed, was the pin connection under sized as engineered, or is there
issue with a ;glow plug ;wire between plugs ;wire size from 12v
source ;glow not shuting off ;over glow?

The burnt pin may not be the cause of your problem, it may be a
result.

Ralph,

I checked the voltage on the small terminal on the starter solenoid.
0 vdc, when I hit the start switch. Next step please?
