8. Rectifier does not shut
down at no load but may shut
down at 10% load or more.
1. Shorted or open triac.
1. Replace triacs.
2. Winding 13 or 14 of T1
or T2 is open.
2. Check wiring associated with
windings 13 or 14 of T1 or T2.
9. Rectifier will not start; ac
is present, digital meter is on,
and Power switch is on.

4. Replace CM3.
12. Battery voltage, measured
by Plt V position on digital
meter, does not agree with
battery voltage measured
across Plant test jacks.
1. Connect a DMM to the Plant
jacks. Hold the meter switch in the
Plt V position while adjusting R15
on CM3 until the two meters agree
within ± 0.02 volt.
13. Rectifier emits excessive
noise.
