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 the input fuse 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 power reduction circuit to protect the charger from
overheating. If you suspect this is the case, refer to the INSTALLATION section for information
about proper charger location.
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.
