Generator

Yesterday morning we lost power at our home for about three hours, so I
started the generator and my wife went out to the bus to get ready. Later in the
day I pushed the start button and nothing. I also noticed the the voltmeter (for
the generator) was all the way to the left. When I attempted to run the
generator out to see if I could find a blown fuse, it did not respond. It seems
like a fuse or relay somewhere has shut off all power to the generator. The
coach batteries are fine and when I push the auxiliary swith it doesn't help. If
someone can give me some help I would appreciate it.

Likely the genset battery is dead. The auxiliary start switch is
powered from the genset battery, if the genset battery is dead it
won't parallel the batteries.

Try jumping the genset battery, it is probably dead. There is a stud-
mount diode and a circuit-breaker in a small enclosure near the
battery chargers through which the genset battery is supposed to
charge, likely one of these is the problem.

Great post Jeff but my idea was KISS

is the master off......

I did that 1 time!

I have a schematic of an 86FC/88 WB. This charging circuit is a
little complicated and our 88 is different than both of these
drawings. I replaced a good battery, before I understood this
circuit.
Our aux. battery solenoid in mid coach under the air step.
You can jumper across this solenoid to start the gennie or keep a
jumper hooked up to charge the gennie battery. Near this solenoid is
a big Bosh relay maybe 50/70 amps, check all the terminals,this area
is exposed to lots of road debris.
This is where the diode (big as your thumb)is located on our 88FC,

This Bosh relay is energized with the ignition "ON" for alternator
charging or when 110V AC is plugged in. So touch the relay box and
listen while someone turns the key to "ON". Then do the same and
have someone plug in the AC power cord. You can hear and feel this
relay activate. This indicates that the charging circuit is
energized.
You can also check the diode with a Volt Ohm meter.
When the Gennie battery is charging their is a slight voltage drop
across the diode ,so the gen volt meter may read less that the volt
meter on the dash.
There is also a fuse and some butt connectors in the left front
overhead, check here ( I hate butt connectors and push on tang
connectors) This is the 12 volt supply to the relay.

This is more than you asked for, It is also another overdesign from
BB. But I just spent several hours trying to understand this circuit
and I had some of the schematics, they were not much help.
This circuit may also be different on your 84, WE have the Onan
Generator.

Dave,
I had this happen to me. I connected my charger to the battery and charged it
and then was able to extend the generator tray. The generator also cranked after
charging.

Jeff,

Thanks so much. Let me describe what I have done so far. The gen battery
was down. It has a quick disconnect so I disconnected it and put a charger on
it. After a few minutes I engaged the quick disconnect and my charger pegged
and kicked out. It is as if there is a major load on it.

When I bought my bus it did not have the original chargers (one smaller
charger). I had an electrician help me install a 2500 Xantrex. That has been
two years and all has worked well ( a few times gen voltage less than main
batteries - pushing aux swith brought it up) . The Xantrex is housed in a box
just ahead of the right drive wheels. There are some heavy cables there, a
solenoid and maybe a diode (about three quarters an inch by one and a
quarter/) with two yellow wires.

Also, I realized awhile back that my gen battery does not start the generator.
My starter solenoid stuck engaged (gen didn't start) so I opened the gen door
and pulled the quick disconnect. It kept turning over until I went to the rear
of
the bus and turned three disconnects for main batteries - that solved it.

The gen battery is charging at this time (group 31 Interstate). If this info
helps
and you have additional direction I would certainly appreciate it. I have had
the stuck starter solenoid about three times. The gen never starts on first try.
It
takes an average of three. I always preheat so I think it may be my lift pump
for
the diesel. I really don't know.

Thanks so very much.

Jeff,

I am both happy and confused. You are right on target for the initial problem.
After charging awhile the gen tray works and the meter shows voltage. I
ventured to start the gen but it only grunted. I engaged the aux and it turned
over just fine. That means the gen batt was trying to turn it over. Maybe my
aux switch stuck on that one time when the starter didn't disengage after
disconnecting the gen battery.

If you have any suggestions as to why the gen starts and dies the first couple
of tries it would help. If I could figure that one out there would be no problem
with the starter staying in. It only does that when it has to turn it over a
lot.

Thanks again - Dave in Tulsa (84PT 40)

Cranking and sticking in the on/start position, could be a solenoid
overheating and seizing in the closed position.

Not starting is probably a fuel problem,, dirty filter, air in the
line, fuel pump, not exercising the gennie, etc.

Bill,

I replaced the starter solenoid, so I think it is primarily having to crank too
long. The starter doesn't seem to stick when I let off as soon as the gen fires.
It
fires quickly but does not stay running but a few seconds. About the third or
fourth time it continues to run. I have replaced the filters. Everyone I have
mentioned it to suppects air in the line. Thanks for the input.
