Onan 6000 Electric Choke
- Thread starter radcaddy
- Start date
That is a Sisson choke used by chrysler and others. The last one I got going was a ground issue because the can that encloses the electro magnet was loose and that's where the coil grounds. It was erratic in operation.
here is a drawing of what is inside. Don't know here you would get another.

Thanks. Yes, the can is jiggly and occaisionally grounds, so the dependability is that it won't work all the time.
Tonight I found this info in some forum that identified the part number for all other uses:
A. The Onan original p/n is #153A233 or p/n 153-0223
B. NSN (National supply number) 2910009630871
C. p/n #VF87A by Wis*Con Motors
Then I found a NOS one on eBay under a Wis*Con Motors p/n search. Pricey, but makes everything happy I hope.

Here is an image of the ground work around. Drilled and tapped the magnet core for a dedicated ground. the insulation on the positive tab was pretty much gone so it was moved also. It now works
I removed the bottom(?) can containing the electromagnet windings by bending back the locking tabs, then removed the original frayed insulation at the tail end of the wire with fresh insulating material.
Also replaced the crumbling mica? insulation layer around and on top of the windings with sheet plastic.
Works perfectly now.

I'm not sure it would, as the choke only engages momentarily - once the genny fires up, it disconnects.

If someone comes up with a plan, I want to know about it. There is an NH in my barn that I can't sell because the choke operator is frozen solid.

Larry,
What is the intended choke pull-off delay, and what is the intended choke pull-off rate? If the requirements are known, it shouldn't be too hard to put together some Rs, Cs, and Qs on a board that could make this happen.

These would move a choke rod around easily enough--rather cheaply too. Obviously you wouldn't mount them on the exhaust manifold. But if a guy needed to improvise it could work. These could be a bit jerky, so if we wanted something slower an HVAC blend door actuator could fit the bill.

Or, convert it to LP fuel. Cleaner and no choke required.
With the small tank of a 23, this could be another issue.

Well now you've just got me wishing I had an Onan with an inoperable choke!
Nothing is easy. The old bolts were soaked for the last week with PB Blaster, but we figured they may shear, which of course they did. The old mounting plate cleaned-up on with the wire wheel and the new part is ready to bolt on IF I can drill out and re-tap the holes. I need a GMC Motorhome Genie.
