General Troubleshooting
To test the auxiliary power
The +5 V auxiliary power is protected by a current overload protection device. If
the current on pins 1 and 39 exceed 0.33 amps, the circuit will open. When the
short is removed, the circuit will reset in approximately 1 minute. There should
be +5 V after the 1 minute reset time.
Equipment Required
Use the multimeter to verify the +5 V on pins 1 and 39 of the probe cables.
