TESTING COMPONENTS IN CONTROL BOX
should be on pin 3, and the "red" lead should be on
pin 5. You should have a reading of approximately
920-1020 ohms.
3. If alternator shows physical damage or does not test
properly, replace it.
KLIXON OVERLOAD (1 PHASE PANELS ONLY)
1. Remove black wire from the bottom of contactor
and the white wire from the "B" terminal for the pump.
Clip ohmmeter leads to the black and white wires
and with the ohmmeter on R x 1, you should have a
reading of 0. If you do not, push in on the reset button
and check again. If you still do not read 0, replace
overload.
START AND RUN CAPACITOR
NOTE: A good sign of a failed capacitor is a bulged or
swollen enclosure, leaking oil or a burnt smell. This is
true on both types of capacitors.
1. With power shut off, short the terminals of the
capacitors together with a screwdriver or jumper
cables. This will discharge any voltage stored in the
capacitor.
2. Remove the wires from the ends of the capacitor.
3. Set the ohmmeter on R x 10,000 (10K) and adjust
needle to zero, after clipping the ohmmeter leads
together.
4. Clip one lead to one side of the capacitor terminal
23833A150 11/08/12
and touch the other lead to the other capacitor
terminal. If the capacitor is good, the needle will go
towards zero and then drift slowly towards infinity.
If the ohmmeter does not read as described, the
capacitor is bad and must be replaced.
5. If the capacity is checked a second time, be sure to
reverse the ohmmeter leads to get a correct reading.
START RELAY
1. With the power shut off, disconnect the wires going
to the relay.
2. Set the ohmmeter to R x 1,000 and adjust the
needle to zero, after clipping the ohmmeter leads
together.
3. Check the resistance between terminals 1 and 2 on
the relay. If the relay is good, the ohmmeter will
read 0.
4. Check the resistance between terminals 2 and 5.
The ohmmeter should read approximately 6,000
ohms. If it reads 0 or infinity, the relay is bad.
NOTE: The relay can check good according to the
above test and still not work properly. The contacts
between terminals 1 and 2, that disconnect the start
winding, may be stuck or burnt together, keeping the
winding in the circuit until the overload trips. If this
happens, replace the relay.
