ONAN starting

Bill,

You're absolutely correct: My latest version is WRONG! I guess when I
looked at the OEM diagram and eliminated the Voltage Regulator, I ignored
that the SCR in the VR was isolating that point from ground.

I'll revise and publish that tomorrow. Gosh, I hope that's the last one!
I think my four score years mean I should give up this sort of thing. :-(
Y'All keep looking for errors -- and consider assuming this task.

OK, I've removed the erroneous ground connection from Pin 8. The revised
diagram is here:

https://drive.google.com/file/d/0B3XquSIYjDleeFphNGM1OXZKd1k/view?usp=sharing

Eventually I'll get that version "KH Onan Wiring 170723" onto GMCMHPhotos
to replace "KH Onan Wiring 170604", but I'm having trouble right now.

Don't feel bad Ken H. Still a lot less mistakes than in most GM factory manuals.

Ken B, sorry i was not able to get back sooner. I am taking readings at the N/O point of K1 that goes to starter and the choke. That wire goes to 8VDC when the engine starts running, from 12.5 VDC and drops to 0 when wire removed from starter and starter disengages.

I have been looking at Ken H's wiring diagram. Someone is going to have to explain to me how the starter solenoid / relay works as shown. I see 2
coils labeled only as K It seems to me that the lower (right) coil would be energized by K1 and in turn would close the K contact to power the
starter.

What confuses me is the other K coil (wired vertically in the diagram). It appears to me when voltage to the K solenoid from k1 is dropped, then the
to two solenoid K coils are now in series with +12 and power is being applied by the closed K N/O contact. If this is true, we would have some
voltage other than +12 or 0 at the K1 N/0 contact that he is reading.

What am I missing here?

Do we have a diode missing in the diagram?

Is the diagram wrong?

Need to think on that one. Have Onan drawing here somewhere. Will dig.

Ken,

I don't pretend to understand the two K coils shown either. But that's
Onan's doings, not mine! I just double checked and I copied that weirdness
directly -- all the way back to 2001.

The only way I can rationalize it is if neither coil can hold the solenoid
contacts closed alone. I'm guessing that the coil in series with the motor
creates just enough contact to activate the parallel coil, which then
firmly closes the contact. When K1 opens, the loss of the series current
allows the contacts to open again. Possibly some sort of arc suppression
scheme? Sort of like the little jumper wire from the + side of K1 to its
contact disc. Duane and I never could figure out any reason for that one
either, except maybe to make it a proprietary part.

I guess someone needs to disassemble and do some tests on an Onan starter,
huh?

Just a thought.
You say you have 33 volts at pin 8 when running.
Can you check the voltage at CR1 and capacitor C1 to see if it's rectifying the 33 volts?
The Dino boards have been known to burn up that R1 resistor.
The original Onan board I have has a 200ohm resistor for R1.
Someone here said the Dino boards have a smaller value, lower wattage resistor.

William,
You stated that you got the Onan (new one) from Jim K. and it is behaving
the same but more frequently. Did you get a new Dino board with the new
Onan. Is there anybody close by you can swap boards with? What is common
with the old Onan and new Onan (remote switch inside coach)?

Ken B I still have old K1 relay that as it turns out is probably fine so I may open and give it a shot.

Ken H, I measured the resistance across in and out on K1, open on both K1's. Resistance from S to the left side of upper K1 ( KH diagram) 4.2 ohms, open to right side.
Choke to ground 1.2 ohms.
Starter solenoid S to ground .4 ohms.

I do not think that I would be chasing the resistor value on the Dino board. That resister is in series with the relay coil of K2, not K1 that we are
working on. If K2 was not working there would be no power to the ignition or fuel pump and the engine would die due to lack of fuel an ignition.

At this point I have seen revisions of revisions.
Could someone please post the last revision with a link to it?

Thank you.

Emery,

I just tonight posted the LATEST revision (just added the revision number
to the drawing). I can't yet get it onto GMCMHPhotos, but this should
work:
https://drive.google.com/open?id=0B3XquSIYjDleZ1lLLWdvX0FaRkU

However, none of the revisions since Sep 2001 affect the area being
discussed in this thread.
