TEST PROCEDURE
1.Disconnect the main AC input power to the machine.
2.Remove the case top and side panels with a 3/8 in. nutdriver.
3.Perform the Main Transformer Test to ensure the proper voltages are supplied to the M19248 snubber PC board.
4.Locate the following leads:
LEAD
208R
209R
354
206
Leads #208R, #209R, and #354 are connected to the rectifier diode bridge (D2). See Figure F.2. Lead #206 is connected at the output shunt. See the wiring diagram.
