Nice analysis and writeup, Jim. While I no longer fool with Onans, I agree
with your evaluation of the problem. I suspect it is equally applicable to
the Onan boards. In fact, I think Johnny Bridges is adding the larger
dropping resistor already.
Y'All are going to keep on until replacing the Onan no longer makes sense!
(Wonder if my son will let me have back the home emergency 4kW he's had
for about 8 years?)

We are replacing the alternator with a transformer

There are a myriad of different ways to go about it - many of which I considered. In my case the design goal was straightforward: solve the problem by: 1) using the existing Dino board, 2) only change the minimum number of components and 3) make no printed circuit board changes.

Gene's approach works well. I used it on one Onan. And I use it, with my
own control circuit, on the TroyBilt generator I now run. It's just a
"wall wart", plugged into the 120vac output of the generator, driving a
"master relay". But then, I don't try to do anything fancy like
controlling the starter -- I HAVE to release the switch, and I CAN engage
it with a running engine. I really don't consider those shortcomings since
I live with them every time I start my cars, truck, or GMC -- and the
generator makes a LOT more noise than any of them! :-)

Hi Ken,
When I first started working with the Onan control boards I asked myself “why go to all that complexity” to control such a simple engine? The conclusion I came to was based on the two points you mentioned. The Onan control board is designed to prevent damage to the unit caused by someone sitting on the start switch for too long - or by hitting the start switch while it is already running. I can’t think of any other reason for it!

As per usual, you are both very observant and correct.
BUT - unlike the general population, you and most successful GMC owners are capable of firing synapses in proper order.
I happen to know why they did this way.
They have to accommodate the people with only average intelligence and nominal understanding.
So, they have to have the starter cut-off and lock out because some people don't recognize that unit has started or is running. I have also seen Onan installations where the engine cannot be heard. (Be nice, wouldn't it?)
They also needed the LOP switch feature. Some people just don't do the required checks.
"Matt, My generator starts and shuts right down." Matt goes and pulls out a dry dipstick.
"When did the generator last get serviced?" Matt hollered up to the owner. Rustle, rustle, muted conversation.
"It was before we went to North Channel." Matt brain grinds out that this was at least three years ago......
If you think this is a joke, go to a marina full of power boats or and FMCA rally. These people are out there.

Hi Bruce,
You can measure the flywheel alternator output between control board terminals 8 and 11. Mine was 30 VAC. Keep in mind that I had only two Dino board specimens to work with - which is an very small sample set. There may be other board revisions out there that deal with the higher voltage just fine and I simply have not encountered them yet. I would recommend NOT implementing my mod unless you had reason to suspect your board had problems. In my case the K2 relay had swollen from the internal heat and the 50 ohm resistor at the bottom of the board was obviously scorched so these may be useful indications of a problem.
> I can see an issue with the transformer approach. You could have an issue with the generator output voltage, yet waste alot of time thinking you have a engine problem because the relay never pulls in.
That is absolutely correct, the transformer approach puts more points of failure in place - and increases the probability of an incorrect indication on which the control system will base its decisions. Perhaps the most likely example of this would be if the genset sits for a while and the remanent magnetic field in the stator naturally diminishes to the point where it cannot begin the self-excitation process. If that happens then the transformer-based solution would never deliver a positive confirmation to the control system that the engine had achieved self-sustain speed - even though in actuality it had. Less likely situations are field assembly failure, bridge rectifier failure and reactor/thyrector failure which would produce identical lies. The Three Mile Island accident is a good example of a control system sensors indicating one thing while reality was completely different and this simple design flaw on a single valve ended up costing the plant owner hundreds of millions of $$ when the power plant was destroyed after only a few months of revenue operation.
In the Onan’s case the control board only uses this information to essentially pull the human’s hand off the starter button - so incorrect indications are not such a big deal.

Fixing the Onan board certainly isn't an economic solution, but it's kind of fun, and keeps the sets original as well as letting me exercise some old skills. I fix them in my coach where I can set the A/C to please me instead of sweating at HER settings in the house.
I've currently got one the PO two back put a 20 amp fuse in. When the coil wire shorted to the block, it removed a couple of runs and the K3 armature departed in a flash of metallic smoke. The 5 Amp is there for a reason. Anyhow, K3 replacements are currently made of Unobtanium alloy. I might get one from Jimmy The K, but he can't sell it for less than Onan gets from him for it which is probably up there.
However, my friends the heathen Chinee list many many relays for very little money. I found a little IC size low current one rated an Amp for the contacts and a 12 volt one rated 10 (Chinese) Amps on the contacts. I'm gonna cascade them and see if that doesn't work. Cost me something like 13 bux for ten of each delivered, and diodes to go across the switched coil were 4 cents apiece when I bought them. The two together are appreciably smaller than a stock K3, if they work properly I'll epoxy them together and to the circuit board. Keep watching this space....

Vi-OLA!!! Or something. I fitted two relays to the board, it fires mine up and runs it and stops it. I ran it half an hour and started/stopped half a dozen times. And boxed the board to send home to Kale Carter. Total cost was less than the small flatrate box which is not a lot. I have relays to do ten more of them if need be.

I agree a VIOLA is a stringed musical instrument.
However, we're discussing the French word VOILA.
Please note that the "I" and "O" are reversed; VIOLA vs. VOILA.
I have seen WAH LAH (or permutations thereof) used many times and in my opinion it's not meant to be humorous; it's because the user
doesn't know any better.
I also campaign the misuse of the word "mute" as noted below:
"It was a mute point."
The correct word is "moot."

AUS '75 Avion - The Blue Streak TZE365V100428
USA '75 Avion - Double Trouble TZE365V100426 I had a day of French in high school. It was the first day and all we covered was "no". Nobody could put enough nasal into it to satisfy the teacher. I dropped the class and took typing instead.
I am pretty sure Johnny was almost certainly joking, or maybe just has fat fingers.
At least when I type or say "viola" for "voila" it is in humor, not ignorance. And now that I know it annoys you, I will be sure to get it wrong for that reason as well.
You probably need to let it go. There their and they're get mixed up, and "would of" instead of "would have". "Till" instead of "'til" (till means cultivate, 'til is the contraction of until). Affect vz effect. I could go on. "I've not" or "I'd not" always get me in the back of the neck for some reason, although they are technically correct. I say "I haven't" or I wouldn't". I guess somewhere in my education someone made it clear that when there is a "not" in the phrase, that'd be were the contraction belongs. It wouldn't be correct to contract the "would" or the "have" if it is followed by "not".

Hay-sus! I post a grin and it turns into a minor firefight. I give you this thought though - There was a guy who decided to meddle in the award of a metal medal to a photographer for his mettle in using a metol based developer in the darkroom. (Metol may be trademarked, I dunno)
