Re: Is it the charger or the batteries that are failing??

Mmmmm… How about getting a multi-meter and setting it for 20 Volts DC. Then touch the prongs to the battery. If the charger is hooked up and running at the time, the meter will reflect the charge being given to the battery by the charger. Unhook the charger from the battery and test the battery posts with the multi-meter prongs – really low voltage registers? Go to paragraph #3.

Another ‘thang’ you can do: It may be the battery (ies) are way down because the charger fuse has opened and it no longer is charging even though it’s lights are on and the transformer is buzzing. Replace the fuse (s).

Sometimes certain types of batteries need coaxing to get them to take a charge when they go to way low. Hook up a wire set leading to a 12v bulb. Attach to the battery for 10 to 15 minutes. Then hook up the charger for 10 to 15 minutes (we have already determined the charger is working from paragraph #1). Depending on the structure of the battery this may take a few times, back and forth, to get the battery to take the 'juice'.

Hope this helps!
