Patterson has a Harrison Heater, common in the early DJ-3As. Attached at the bottom of the dash is an Ark-Less four position switch (Off, Low, Medium, High) that controls the fan speed. The switch wasn’t delivering current, so I spent the day figuring out how to pull it apart and clean it up in the hopes that the switch could be resurrected.
The switch is held together by a long pin in the center. The switch also rotates on this pin. To remove the pin, the rounded edges on the pin must be drilled/pressed together/or someone modified. I chose to drill out the ends.
Here’s what it looks like to begin (not my switch .. I forgot to take this pic .. thanks to the cj-2a.com page)
Note the small hole. That pin must be pushed out
Now, here’s my switch. It received some paint when Patterson was repainted (I believe the paint was touched up some at some point). Once I drilled out the end of the pin a little, I used the nail to push the pin through.
Here’s the other side of the pin. Now that it is sticking up, I can remove it.
Pin removed. I didn’t put much pressure on the pin when I first pushed it through, so I *think* the pin was already bent somehow.
