Adjusting a mechanical chaser controller

posted by popcornn on April 14, 2008 at 10:45 am

So I have a 4 circuit Time-O-Matic Model 2 Chaser controller (with new contact points now!) that needs to be adjusted (I assume). The contact points can be threaded in and out which determines how far the gap is for each circuit.

Does anyone know how to set this type of unit so it operates properly? It’s 1940’s technology, but still needs to be set up properly to work!

If the gap is too close you’ll burn those new contacts up in no time due to excessive arcing. I think I set the ones I repaired several years ago to 4 business cards thickness.

If you get yourself a cheapo two wire extension cord, you can chop off the female end and use what’s left of the cord as a power cord to power the chaser on your work bench before putting it back in the sign.
