GENERAL TROUBLESHOOTING GUIDELINES

This troubleshooting section is organized into three basic problem sections:
electrical troubleshooting, console diagnostic tests, and mechanical trouble-
shooting. Once you have identified the problem section, perform all the tests in
the same order as written. To order a replacement part or for help with trouble-
shooting, contact our Customer Service Department. Refer to the Appendix for
the appropriate phone number.

ELECTRICAL TROUBLESHOOTING

The 4600/4400 PT electrical system has four major components: the alterna-
tor, the power supply, the power cables, and the console. The 4600/4400 CL
has five major components: the alternator, the power board, the battery, the
power cables, and the console. The console, power board, and power supply
are not serviceable by the owner. If any of these parts are inoperable, they
must be replaced. Opening the console or the power supply will void the
warranty.

4600/4400 PT

1.

Use a voltmeter set on VAC to verify that the AC wall outlet has 100
to 120 VAC (or 220 to 240 VAC, if applicable). If you do not have a
voltmeter plug in an alternate AC-powered device (e.g., a lamp). If the
device does not work when plugged into the electrical outlet, consult
an electrician for further assistance and then retest the electrical
outlet.

2.

Plug the power supply into the wall outlet. The green Light Emitting
Diode (LED) on the power supply should be on. If the LED does not
light up, replace the power supply.

3.

Disconnect the DC cable from the left side panel. Set the voltmeter to
VDC and test for 12 to 19 VDC in pins #1 (+) and #2 (-). Replace the
power supply if the voltage reading is outside the specified range.

4.

Remove the bottom cover and connect the DC cable to the power
connector on the left side of the frame. Locate the black and white
wires on the backside of the power connector.
