2. A BAD BATTERY CHARGER. If the battery open circuit voltage is low and/or the hydrometer indicates your batteries are low, the
battery charger should be providing current to the batteries. If it is not, check A.C. input and check to see that you have charging
voltage on the output with no battery attached. Note: You will not get an accurate voltage reading on the output of the charger with no
batteries attached. This is checked merely to ensure that you do not have an open circuit on the output.
The battery charger has a thermal cutout switch to turn the charger off if it is overheating. If you suspect this is the case, refer to the
information regarding charger location in the Installation section and cooling fans in the Application Notes section.
3. ELECTRICAL LEAKAGE. You may have a previously unsuspected source of current drain from the battery. To check for a leakage of
this sort, disconnect the battery ground cable and connect an ammeter between the negative battery post and ground. If you have a
reading over .1 amp, there is a source of current drain from the batteries which must be located and removed.
