Troubleshooting
Taking the following measurements can check the transistor and diode.
Q1 | POSITIVE PROBE | NEGATIVE PROBE | READING |
DP | R2 | L1 | 0.312 |
DN | L2 | R2 | 0.312 |
QP | L1 | R2 | > 0.6 |
QN | R2 | L2 | > 0.6 |
TRANSISTOR AND DIODE CHECK USING D.M.M. SET ON DIODE SCALE
FIGURE 10
If the Green POWER indicator light on the front cover is out make the following checks.
1.Check for the supply voltage between L1+ and L2-
2.If the supply voltage is present replace the entire RPM unit.
