Default Onan Ignition Coils - Substitue with something cheaper?

Im currently working on getting a BGEFA-26100N Emerald Plus 4000 genset working.

I've got power goign to the ignition coil, but it's not producing high voltage.

I've priced "Onan" ignition coils and it's about 1/2 of the worth of the genset.

What is everyone using as a substitute?

Thanks,

JohnnyO

Harley Davidson motorcycle and Victory Motorcycles by Polaris Industries inc. use Dual coils or you can hook two auto Coils in series and use them they are not pretty but they do work. Doug.

Hey LawDawg, I've got 3 of these things..... AND I see you're about 90 mins away from me ...... This one is an Emerald Plus 4000 , the other 2 are out of older motor homes but both have less then 800hours on them.

I'm pulling the other 2 this weekend. One is actually "GOLD" in color....

some motorcycles used 2 coils wired in series.you could also use motorcycle twin coils like from older hondas.

Smile Re: Onan Ignition Coils - Substitue with something cheaper?

Make sure you check out the rest of the ignition circuitry before assuming that the coil is bad. An ohmmeter check of the primary and secondary windings should reveal an open circuit in one or the other if the coil is really bad. The insulation on the secondary of the coil can also go bad, causing it to arc internally, resulting in no spark. Many people replace coils, only to find the problem to be elsewhere. I'm not sure what circuitry your unit has to operate the coiol (points and condenser, or electronic pickup, etc.). Posts above are correct, should the coil actually be bad.

I tested the coil with an OHM Meter ..... The reading was 33 vs. the 3.8 - 4.2 it should have been. This is why I assumed the coil was bad.

I have almost 11vdc going into it and zero spark coming out.

Johnny:

If you were to go to your friendly NAPA store and get two -matched- (same part number) regular point-type 12 volt coils, you should be in business.

Simply connect the two coils in series. + on one coil to battery (or ballast) - on that coil to + on the other coil. Then the - of the second coil to the points and condenser. One coil drives one plug and the other drives the second.

Should work.

If your genset doesn't have a ballast resistor in the ignition and the coils run hot when the engine has been going for a while, you may want to get a ballast for, say, a 65 Chevy (or any other point ignition car of the era) and hook it in series with the coils.

Take care - Elden

What is your coil part number, many onan twins will use an onan 166-0820 replacement coil. Search the internet for onan 166-0820. I found these priced from 68-75 dollars. You may save money with the two coils but do you want it to fit in original location etc? Your choice. If I am off base with this part number one of the local experts will correct me. I bought one of these for a cck about three years ago and paid $80.00 for one. It sure fit in original cover and works but.... now I am older and hopefully a little wiser. I didn't shop around but just bought it. Luck , Ben
