Test Power Supply Resistance

A
(See Fig. 5)
Remove the power supply (18) from the gun. See page
36.
Measure the resistance from the power supply's
ground contact point (EE) to the contact inside of the
power supply seal (18e) [the conductive rubber contact
may be slightly recessed into the seal] . See Fig. 5.
The resistance should be 297 to 363 megohms. If the
resistance is outside the specified range, the power
supply is defective and must be replaced. If the resis-
tance of the power supply is correct, proceed to the
next test.
If you still have problems, refer to Electrical
Troubleshooting for other possible causes of poor
performance, or contact the nearest authorized service
agency. EE
