On a 6-volt battery you should have slightly over 6 volts like 61 to 63. You would use the same procedure you used on the DC cord.
With the key off and the cart direction switch in a neutral position set your voltmeter to ohms and place a probe on each large terminal see first image below.
How do you know if your golf cart charger is bad. If the charger makes a loud clicking noise this is likely a battery charger issue. Learn more about the signs of a bad golf cart battery. Get a brush for cleaning off corrosion and rags for wiping off leaking acid.
Remove the charger cover as explained in Step 4. To best protect your batteries make an effort to wipe down golf cart batteries every month or so. So being if the golf cart battery cable lug connector or connection between two batteries is bad the cart will usually not work drive or charge.
Typically a charged battery pack will have 2-3 volts higher on a charger than its rated voltage. If you get continuity in both positions the diode is bad. Failure by the cart to start is.
Two things could be going on here. How do you tell that your golf cart batteries are failing. If you get a reading of something like 41 then one of the cells in this unit is bad or shorted.
If the timer unit is incorporated into a solid state circuit board which has gone bad then the charger may not even cut on. Be sure to wrap the cable ends in tape and keep the ends separate from each other. T imer units diodes and bad DC charger plugs are the most common failures in golf cart battery chargers.
If your electric golf cart experiences shuttering you can take it to mean that it has low voltage. Touch the red lead of the multimeter to the other side of the fuse and listen for a beep. Example Running a trickle charger at 5 amps on a battery bank for a long time while on vacation will eventually dry the batteries out if not maintained and that will ruin the batteries not the volts or amps being applied It is the nature of the battery chemistry when your golf cart battery charger is charging or when you are using the golf cart driving and applying a load Off.
If you see leaking acid remove the battery immediately and replace it. Lift the golf carts bench seat to gain access to the engine. When replacing any component of your charger check your warranty if you have one.
Determining if the controller is bad is a relatively simple procedure. On an electric golf cart the most common symptom is the solenoid is not delivering electricity to the controller when the vehicles ignition is turned on. If the charger doesnt turn on then there is a problem with the connection between the charger and the battery.
Another way to see how your batteries are holding up is to test the voltage of the golf cart batteries. Locate the governor on the engine. Dispose of your battery carefully as lead-acid batteries can be an environmental hazard.
The following are possible symptoms that may act like warning signs for a failing battery or batteries. Look at the cables on the battery charger. Ground the black lead of the multimeter on the screw next to the fuse.
A bad timer unit usually will not allow the charger to cut off. This is the small T-shaped metallic rod around the top of the golf carts motor. Shuttering could also be an indication that your chargers are not functioning properly.
If the multimeter doesnt beep it means its not working. You should have a professional examine it. Turn the ignition to auxiliary.
In normal operating conditions the solenoid clicks on and off with the ignition switch. If the charger makes a clicking sound when you plug it in and then does nothing this is a strong indication that the charger knows its time to charge but is failing for some reason. Disconnect any cables from the two large terminals.
If you get NO continuity in either position this would also indicate bad golf cart charger diodes. Unplug the AC and DC power sources to check the AC cord if the charger isnt humming when plugged in. Test the golf cart chargers fuse with a multimeter to see if its bad.
That would indicate that the golf cart charger diodes which are one-way gates for electricity are working normally. For example a 48 volt system will have 51 to 52 volts after a full charge. A failing solenoid will generally not click.
If you dont hear a beep that means the fuse is bad and needs to be replaced. How To Test Golf Cart Batteries With A Hydrometer Specific gravity can be measured using a hydrometer. IN GENERAL if the charger kicks on but doesnt charge fully or kicks off soon after this is likely a charger issue.
So check all the connections and cables for signs of corrosion or wear or completely broken off battery. Use the volt meter to check the continuity of the AC cord. We can test this by using a.
