SYSTEMS DISPLAY PANEL TEST

The only repairs that can be made to the systems display panel are replacement of bulbs and replacement of the hour meter. If there is a problem in the systems display panel, replace the systems display panel.

Put the key switch in the ON position.
Push the check-stop/alarm button.

All of the indicator lamps, warning lamps, and machine gauges must illuminate.
If the indicator lamps and warning lamps illuminate but the machine gauges do not, see Section 4001 and check the systems display panel. If the readings for the systems display panel are correct, replace the systems display panel.

If machine gauges illuminate but some or all indicator lamps or warning lamps do not, see Checking and Replacing Lamps in this section and check the lamps. If the lamps are good, see Section 4001 and check the systems display panel. If the readings for the systems display panel are correct, replace the systems display panel.
