Thanks for the advice.
You are absolutely right, one of these relays had an open coil.
Rick VE7ASR and I opened up the Jupiter and located the
defective
relay this afternoon. I'll be calling TenTec on Monday to order
the part, plus a spare of course.
I imagine Rick will be documenting the repair on his web site.

Do you bank? Do you use ATMs? Then you've used IMS.
Nothing has ever compared to the reliability and speed of IMS.
