I am looking for proper documentation for setting up the mechanical "timing" and synchronization of the solenoid switches etc. Right now I pretty much wing it and make sure it cycles "properly ?". Sometimes works and others, the Solenoid(s) will remain energized causing much heat. I figure there is a step process to preset switch activation.
Thank you Dave

Maybe look for something in a classic Corvette, Cadillac, or possibly Oldsmobile discussion board and/or Clubs? A working Delco WB in these classics would be an important item. So there is someone they know who works on them and would share some secrets?

Hi Dave,

You have to find a factory-shop-manual, not the Fisher-body-manual, it contains a real manual and a schematic
about the car radios.
That is common on all GM, Ford and Mopar shop-manuals.

If you own the car, too, you have to have one anyway.

Regards,
SIXMILLION DOLLARMAN :wink:

I have this radio working as it should mostly. Occasionally, it will leave a solenoid stuck energized. It is the kinetic spring solenoid. I have disassembled and cleaned the grounding contact thinking it might be getting stuck. When it sticks, the solenoid heats up rather quickly and has had me going for the power connection quickly. Not sure why. It seems to happen when the treddle solenoid approaches synchronization with the kinetic solenoid. The treddle solenoid releases when the "governor" relay disengages. So far it has not posed a problem but I am skeptical.

At the moment I am going to try a self-resetting automotive "fuse" in the solenoid common line. It seems when the 'stick' happens, it unsticks when power is reapplied. So, we will see.

Other ideas?

It has been a LONG time since I worked on one of those, but I recall that there are two switches which control the solenoids. Make sure that the switches and the mechanism are not hanging up, and check the contacts on the relay. As I recall, one of the solenoids returns the dial mechanism to 550 khz, and should engage when the dial mechanism reaches the 1600 khz end, The other solenoid winds the spring mechanism; it should engage and rewind the spring, when the spring mechanism "unwinds".

It's covered in the Sams AR-7 manual, but there is nothing on the tuning mechanism; one would have to find the original Delco manual for complete information.

Try powering it with a car battery, most power supplies don't have enough amperage to operate the mechanism correctly.
