Things You'll Need:
- Volt-OHM Meter
- Clear work area, preferably a garage floor
- Patience
-
Step 1
* Check the primary voltage to make sure that the battery charger will have voltage to it from the wall socket or other source. This ensure that the circuit you are working from is live and not dead.
-
Step 2
* Remove battery charger from power source. Make sure that the battery charger is not connected to any outside cables. Disconnect the charger from all of its cables. This will isolate the battery charger from all outside power sources.
-
Step 3
* Take your OHM-Meter set it to (R X 100) Take the incoming power cord to the battery charger and connect the leads (power wires) to the black wire on the battery charger onto the black wire on the OHM-Meter. Now, place the white wire on the battery charger, onto the red lead on the OHM-Meter. Disregarding the ground wire (grey wire) Verify that the meter is receiving a reading, you will know this if the pointer moves on the face of the meter.
-
Step 4
* If no reading. Check for fuse or some type of overload switch in the circuit. If you find a fuse, other than a glass fuse, check it with the meter the same way as you checked the circuit on the battery charger. If the meter pointer moves, the fuse is good. If you find an overload switch, place a meter lead on each side of the switch, if the meter moves the switch is closed and the circuit is ok. You have now completed checking the primary circuit of the battery charger.
-
Step 5
Special Note: The primary circuit of the battery charger, is usually supplied by a 115 volt AC or 230 volt AC, which powers an AC transformer, stepping the voltage down to approximately 40 volts, which is then rectified and converted into direct current.
-
Step 6
* We will next test the secondary circuit of the battery charger. Set up your meter as follows:
-
Step 7
A) Fine the common connection indicated by a (-) negative sign, and place the black lead into the connection on the OHM-meter.
B) Place the red lead in the V-Pus connection indicated by a (+) plus sign.
C) Set your meter dial to DC 60
D) On the output of the battery charger hook up the OHM-Meter onto the battery charger with the plus to plus, and red to red. Also hook up the black to black, and negative to negative.
E) Carefully plug in the battery charger to your power source.
F) Now the OHM-Meter should read approximately 40 volts. If this happens then,
G) Disconnect the battery charger from the power source, and connect the battery chargers output to the 36 volt batteries, plus to plus and negative to negative. Make sure it is not hooked up backwards.
H) Plug the batter charger into the primary circuit, and turn the battery charger on. You will probably hear a hum. Take the meter and place the test leads onto the battery terminals where the battery charger is connected, still observing the negative to negative and plus to plus. Your meter should read, slightly under what it read "before" the battery was connected.

on 7/21/2008 The charger has to sense around 28 volts for it to come one. Without batteries there is NO WAY for the charger to com

on 6/21/2008 This is NOT HOW you test a 36 volt golf cart charger or any golf cart charger for that matter. If you follow these testing procedures the charger will FAIL EVERY TIME! DO NOT FOLLOW THIS GUIDE!
