I have 2 of these Motorola service monitors. 1 working and one with a bad internal reference 1mhz module (burned) and low voltage power supply ( burned diodes). I am looking for schematics for the reference osc crystal heater and osc assy and the low voltage regulator board. Ideally I would like to locate a service manual to rent or borrow or buy. I expect this failure has happened in the past and someone may have a few tips on it. Can respond off list [EMAIL PROTECTED] Thank you in advance. Arthur Carlson Saint Cloud Mn.
