
WARNING
Capacitor may be charged. Once discharged,
a transient recovery voltage may be gener-
ated in the capacitor after a while. Always
discharge capacitor before servicing.
Removal
Removethe30Afuse.
Connect a test light to capacitor terminals during
a complete minute to discharge capacitor.

WARNING
Do not short–circuit both capacitor terminals.
Disconnect capacitor terminals and unfasten ca-
pacitor.
Inspection
Visual Inspection
Check for pin holes in the pressure relief valve on
top of capacitor. If any pin hole is present, discard
capacitor.
Charge Hold Test
Connect a 12 V test lamp to capacitor terminals
during a complete minute to discharge capacitor.
Connect a switch (in OFF position) between a 12
V battery positive post and the capacitor positive
post. Connect the battery negative post to the ca-
pacitor negative post. Turn on the switch for 2
seconds. Disconnect the capacitor from the bat-
tery.
Note battery voltage.

WARNING
Always respect the polarity when connecting
the capacitor.
Wait 5 minutes, then measure capacitor voltage.
It must be within 1 V maximum of battery voltage.
If in doubt, proceed with the following residual
voltage test.
Residual Voltage Test
Connect a 12 V test lamp to capacitor terminals
during a complete minute to discharge capacitor.
Connect a switch (in OFF position) between a 12
V battery positive post and the capacitor positive
post. Connect the battery negative post to the ca-
pacitor negative post. Turn on the switch for 2
seconds. Disconnect the capacitor from the bat-
tery. Note battery voltage.

WARNING
Always respect the polarity when connecting
the capacitor.
Connect a switch (in OFF position) and a 300
5 W resistor to the capacitor. Turn on the switch
for 12 seconds ± 1 second of discharge.
Residual voltage after 12 seconds ± 1 second of
discharge must be above 5 volts.
Installation
Connect a 12 V test lamp to capacitor terminals
during a complete minute to discharge capacitor.
Make sure 30 A fuse is removed.
Install the capacitor.
Make sure to connect BLACK wire to negative ter-
minal and RED/WHITE to positive terminal.

WARNING
Always respect the polarity when connecting
the capacitor.
Install the 30 A fuse.
