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)
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.
