Charger Capacitors

Charger Capacitors

This section contains replacement capacitors for various E-Z-GO & Lester 36 & 48-volt golf cart battery chargers. The important thing about buying a capacitor is matching the 'micro-farad' rating of the original capacitor, and matching the charger output voltage rating (36 or 48 volts).

The replacement capacitor must have the same 'micro-farad' rating as does the original. The abbreviation for micro-farads is 'MF' or 'MFD'; so when you see 20.5 MF, this means a 20.5 micro-farad rated capacitor. The physical shape of the capacitor does not matter. It may be round or oval, so long as you have room to mount it.

The charger will not charge properly if the capacitor is bad. To check a capacitor use an ohm meter. Touch the red meter probe to one of the capacitor terminals & the black meter probe to the other capacitor terminal. Now reverse the probes such that they are now touching the opposite capacitor terminals. The meter should display a read out and then quickly return to no read out. Reverse the probes again, and the meter should react the same...quick readout and then no read out. This indicates a good capacitor. If you are using a needle style ohmmeter, you will see the needle deflect and quickly return to zero. 

CAUTION! Capacitors store electricity and they can accidently discharge with a flash of blue light and a loud pop! Before proceeding with the ohm meter test, touch both capacitor terminals at the same time with a screwdriver blade (be sure you are holding the plastic handle). This will discharge any residual electricity stored in the capacitor. The sudden discharge of the stored electricity will scare you and shock you.

Always disconnect the charger from the AC wall circuit and from the golf car before opening the charger case.
