I'm sorry to tell you, from experience, that 6 hard faults in a row
on the 87A results in the microprocessor shutting down.  You may contact
Ray Heaton (sp?) and if you can connect it to a computer via RS232,
he may be able to tell you over the phone what the problem was that caused
the 87A to have 6 hard faults in a row.  However, it may be easier to
simply remove the transformer and send the unit back to Ray Heaton.  Be
aware that (1) they have moved and that you should find out the new address
and (2) there is currently a 6 week backlog at the repair center according
to information I received last week from a ham who owns the one I bought
originally.

In the future (again, from a unpleasant experience), DO NOT try to restart
the 87A more than 3-4 times without noticing the binary coded leds and
determining from the manual what the hard fault is.  If it cannot be
corrected easily, you might as well bundle it up and send it back.

Sorry to be the bearer of bad tidings...  Rod

Dale:

There is a way to reset an overcount of hard faults. Just briefly connect
pins 13 & 14 of your serial connector on the rear panel. This according to
info given me by Chris Mason at Alpha abt 2 yrs ago. I don't recall if I
ever used it, don't hold me responsible if anything goes wrong (nothing
should).
