d. By touching the + side of the tester to the - terminal of diode
module and the - side of tester to the ~ terminals (3 NOs.) of the
diode module, measure the resistance.
If all the resistances are greater than 500kΩ, it is normal.
• Checking procedure for the ISPM
Rectication parts of internal circuit of ISPM (Common)
Remove all the terminals of the ISPM before check. If items (a) to
(h) are performed and the results are satisfactory, ISPM is normal.
Measure it under 1 kΩ range of a tester.

• Perform the high voltage discharge procedure as de-
scribed
• Do not use a digital tester.
