I ran my generator 2 hours every 5 hours or to power refrig and freezer and microwave when power was out for a few days. No problem it ran fine. The load is not very high from those items. I made a trip and had to stop and it was hot so I cracked up the generator and turned on both AC UNITS. It ran for about 20 minutes and quit. It was 94 out side and when I used the generator to power the house it was about 80 out side. It seems every time I make a trip and it is hot out side it quits when I need it. I really need to be able to use it when traveling when it is hot since my wife likes to sit at the table while I drive.

What would be a few things I need to check. The oil level checked ok.

I am planning to run it and load it next wk when it is hot outside; I would like to fix it so I can depend on it when I need it if possible.

Last year: Compression checked out. Installed new point and condenser. Changed coil to see if that was the problem. Made sure no air leaks around the filter. It ran fine when I was checking and it was hot outside. It was also pulled out when I worked on it.

Well it takes, spark, fuel, air, and compression to run. You need to determine which one of these is missing when it fails to run. Usually it is spark or fuel. Once you determine that, we can go from there. There several other issues associated with the control circuits (the board) that could be shutting off the spark or the fuel. Once you determine which of the above 4 is missing we can go into the board if necessary.

Art,

The first year we toured the east coast in Double Trouble the Onan ran
perfectly.

The second year it developed a problem just like yours. Tom Hampton
discovered that it was the coil failing when it got hot.

Someone reported they had a fuel pump that seized up when hot and I had a
coil that would fail

The other thing I was wondering how much load are you putting on the Onan?
If you're running both A/C units, the hot water heater, AC powered DC
battery charger / convertor, refrigerator, lights, etc. you could be
overloading the Onan.

I had both AC running (each 13.5 and newer unites), plus refrig and battery charger. Last year with all running plus the hot water heater the I had the current checked and it drew 28 amps.

Art,

Well overloading isn't the reason then.

You mentioned you changed the coil last year did you install a new one or a
used one?

I bit the bullet and bought a new one from Onan even though it was over
$100!

I have mentioned that Harley Davidson's use a dual fire coil on their
V-twins. You can get a coil for a hell of a lot less than $100. In fact
quite a few guys replace their waste spark ignition system with a single
fire system so they can set the timing for each cylinder individually. They
flog the old coils for twice nothing. Do a search on eBay for
Harley-Davidson Ignition Coil.

Rob M.

Looked on ebay... They look an awful lot like the coils used in "coil packs" on a lot of cars. (For example, Item number: 280698593027 ) You would only need one of the 3 or 4 coils. You would have a spare or three... Laughing

In fact, you might be able to find a pack with at least one good coil in the trash at a local auto repair garage. Note that a lot of these packs include the "igniter" in the pack.... so they go bad just as often as the coils. So.. these coils might be easy to find for free.... (I haven't looked.)

Mike,

It looks like there's two power supply wires going in and two spark plug
leads coming out so that Toyota coil should work.

The price is right! ;-)

It was above 90 so I tried the generator. It ran about 15 minutes and quit. I pulled out the generator and started right up and quit. I choked it and was able to keep it running. After a about a minutes it started to run by itself. The filter is new. The carb was cleaned this winter. The line to the tank was replaced this winter. Has anyone had a problem with the fuel pump when it gets hot?

I assume since it started right back up that coil is good.

If you find a suitable replacement, like that Toyota coil, please be sure to let us know. It would be very helpful to be able to replace the Onan coil with something that the local parts house stocks.

Thanks!
