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.
The MEC battery charger is a fully automatic type with a maintenance feature that will maintain
battery voltage indefinitely when connected to an AC power source. The battery charger should
be plugged into an unswitched AC source if stored for long periods of time.
