General Troubleshooting
The following chart lists general troubleshooting guidelines for the SR-100i
system when the logic-regulator status LED’s do not give any insight to the
particular problem being experienced. Please contact KALIBURN technical
support for any issues not covered in this section. Before any tests are performed,
make sure that all system fuses are good. The primary system fuse F1 is located
on the rear panel of the unit. The control fuses F2 and F3 are located behind the
rear panel of the unit on the sub-panel.
Problem Possible

4. If the STRT LED does not illuminate, check
for contact closure between P8-3 and P8-4 or
