Questions (3)

How can I determine if the 5198 power supply is causing a problem?
Use this procedure to test the power supply to make sure that it is the device that is causing a problem.

Remove the power supply connector (P1) from the 5207 board. Disconnect the battery from the power supply. Make all power supply measurements with 120 VAC applied to the power supply.

Place a 4.7k resistor between pins 1 (brown) and 3 (orange). Use a DC voltmeter set to the 50V range to measure the voltage across the resistor. The voltage reading should be between 26 and 28 volts. Remove all power from the power supply before replacing connector P1 on the panel.
