Service

All work for the LMESpro charger should be performed by a qualified electrician. La Marche is not responsible for

any damages caused by an unqualified technician.

CAUTION:

Before working inside the LMESpro charger ensure that the AC power is off. Disconnect the

battery/HCAP from the charger. Verify that no voltage is present by using a voltmeter at all input and

output terminals.

User Serviceable Parts

Other than the AC & DC fuses, there are no user serviceable parts within the LMESpro. Only replace fuses with

the same current and voltage ratings, never substitute a larger ampacity. See Figure - 13.
