Warning!!

A designated Positive (+) & Negative(-) input cables to

the DC2DC charger MUST be connected to the engine

start battery terminals. Using the vehicle chassis as an

earth return is not permitted.

For late model vehicles fitted with Smart Alternators, the

Negative (-) cable must be attached to the “vehicle” side

of the alternator sense module.

Failure to follow these instructions will result in spiking

the DC2DC unit and causing the internal input fuses to

blow.

This is not covered under warranty and the fuses are not

field serviceable.

Vehicles with a Smart alternator,

the Negative cable must be

connected to the vehicle Side
