Incorrect assembly may result in a risk of electric shock or fire. The following procedures are
intended only to determine if a malfunction may exist in the charger. Most returned chargers test
good, it is very important that this procedure is followed and that other problems are corrected
before assuming the charger has failed.

battery voltage indefinitely when connected to an AC power source. The battery charger should
be plugged into an un-switched AC source if stored for long periods of time.
