Wild Generator Oil Pressure

[Gus]

Hello everyone,

On my last trip, I noticed the generator oil pressure bouncing
wildly between 80 & 120. I did not notice it creep up. It had
been just under 30 psi for most of the trip (15hours). Water temperature
was at 160 F. I was alarmed so I hit the switch to turn it off. It
did not shut down. I pulled over, opened the generator bay and access to
the controls. I hit the off switch at the box and nothing. The
engine did not feel too hot to the touch. The radiator and the coolant
reservoir did not feel too hot either. I was still alarmed so I pulled
the fuse to shut it down. I reinserted the fuse and tried to start it,
but was unsuccessful. I then checked the battery and it was dead.

Other information:

1)
I had just replaced the battery and was aware that the
battery was not being charged by the battery charger or the generator.

2)
As I was trying to shut the generator off, I noticed
that the switch was lit dim. Is that because the batt. Was dead (8 volts)?

3)
As I was checking the battery, I felt a very
small electric charge on my left knee which was touching the bus frame.
Should I be concerned? I will investigate that charge further tomorrow
morning. It may be unrelated.

4)
I am now charging the battery so I can try to start the
generator in the morning. I think it will start but I will not let it run
for long until I figure out the Pressure problem. Is battery
voltage required to shut it off?

5)
Right now all the gauges read zero except for the
oil pressure. The needle is stuck at 60 psi.

6)
By the way, I have a 13 kw generator with a Yanmar engine.

Any help is greatly appreciated.

I had the same two problems w/my PT36 (not at the same time). If the
generater batt. is dead there is no power to energize the shutdown
solenoid. There are probably other ways to do it but I hooked up my
battery charger and that furnised enough power to activate the
shutdown solenoid.

My oil pressure guage was also flucuating like your's. What I found
was a poor ground to the guage casing. Without the ground the guage
will read all over the scale. The ground must act as a bias.

Hi Gus -

The oil pressure guage is surely electric. The genset engine
controls would also be electric and possibly electronic.

Now, you also mention the battery is low or dead. Your electric
guages and engine controls will certainly be erratic if the voltage
is wrong.

Try charging (and doing whatever is needed to KEEP a charge) and then
see how everything works.

Best of luck.

some times a high oilpressure at low idle followed by a drop off to
less than idle reading but more than normanl as you increase rpm
proves the relief is being used in the filter. you would think
Chatter in the gauge is also an indication but i dont think the
pressure can fluctuate fast?? when a filter gets dirty quick, it
could be a bearing got ate up and clogged the filter media.

Your situation sounds like a battery ground especially if the
genset is started by a dedicated battery. for it to be an alt issue
that kills the battery while the engine is running, the fuel shut
off would close and stop the genset. Since the genset ran on a
battery either dead or not connected properly, the alt must have
been supplying the juice to keep the fso open?????? it would be
helpfull to know if the battery was actually dead, if not it could
be just a bat terminal issue

I guess the relay power to throw the fso is via the genset
battery???? cant understand why you could not remove power to the
fso??? you would think that relay is normaly closed?????

After charging the battery externally 12 hours it finally
reached a full charge. I thought it may have had a bad cell, but it’s
ok. I installed it and started the generator. It started up fine just
like it always had in the past. All the gauges seem to be working properly.
I paid close attention to the oil pressure and it indicated in it’s
normal range. The switch was not dim as before and I was able to shut it
down and power it up from all the switches. I believe the low voltage in
the battery is what caused the wild readings as was suggested. I have not
checked the ground to the gauge yet but intend to.

I still don’t understand why the battery is not being
charged. Is it supposed to be charged by the generator as I’m going
down the road or is the charger/inverter supposed to do it? Even if nothing
is charging it, would the voltage be consumed after 15hours of runtime?
What is consuming it? I thought that the battery was only needed to start
(and now obviously stop) the generator.

Does anyone have any suggestions as to how I can keep it charged
while I’m on the road? It is a dedicated battery for the genset.

In the past I have been using a small battery charger while it
sits. I didn’t have any problems with that set-up because I had not
taken the bus out for any extended runs. My trips had always been
relatively short.

Thanks for all the info and suggestions. I’m still
relatively new to bird ownership but I’m learning thanks to all the
support I get from the good people in this group.

It is running the electric fuel pump for the generator. On mine the inverter/charger charges that battery. On some models the generator has an alternator. The engine alternators should charge it going down the road in absence of the genset having an alternator. There have been several posts about a diode or resister, cannot remember which that folks have retrofitted when this problem occurred. I just cannot remember what it is, getting old. Type in search and see if you can find those threads or perhaps someone will say what they did. I think all of this is correct.

I should have said the inverter/charger charges it when it is plugged to shore power.

There have been several posts about a diode or resister, cannot remember which that folks have retrofitted when this problem occurred. I just cannot remember what it is, getting old. Type in search and see if you can find those threads or perhaps someone will say what they did. I think all of this is correct.

Gus,

On our 88 FC, and I believe that your 89 may be the same,
There is a large Bosch relay, probably 70/80 Amps. The size of a
pack of cigarettes, located mid-way center under the coach,
The relay is tripped by 12V when the engine is running or when the
gennie or shore power is applied, to charge the battery with the
battery charger. This is also where the diode is located. It is round
about the size of your thumb. These wires are exposed to the
outside road debris, usually cleaning all the wires, contacts and
butt connectors will cure the charging problem.
The gen battery should charge from the engine alternator or the AC
battery charger when on gennie or shore power.
You may see this charge on the generator Amp Gage.
For a temporary fix a jumper across the diode will charge the battery.
This jumper must be removed as several batteries are connected
together, The jumper could drain the batteries.

Bill 88 FC Michigan
