Matrix: IMF-3 power supply indicator failure troubleshooting
Question: The LED marked "-" (analog supply) on my IMF-3 is not lit. With the LED off, has my IMF negative rail failed?
Answer:
1.) Check the fuse block on the front panel of the PSU-101 power supply unit. To open the fuse block gently press down on the top of the block and then pull the block forward to expose the fuse. Check fuse and replace if necessary with a Bussman GMC3A fuse.
2.) Verify that the power cord is properly connected to the PSU-101.
3.) Check that the Jones power cable is properly connected between the PSU-101 and IMF-3 frame.
