Maintenance
Fuses
The fuses in this equipment are not expected to fail in normal operation. Their
failure may be an indication of equipment malfunction requiring qualified repair
personnel.
There is one fuse associated with the spark tester’s operating voltage, located in
the ON/OFF power switch on the back panel of the unit.
Two additional fuses that could be defective are found on the relay output
printed circuit board, behind the back panel.
