LC Current Limit Wiring

LOCK

Off position where no accessories will work, and steering is also likely

locked

Cranks the engine on and reverts to ON position.

ACCESSORY

Accessories are given power such as radio and some other small

electronics.

START

Turns on all your electronics. The key will default into this position after

cranking in START. Splicing of fuse block will need to be live when the

key is in reverting back to this position

Review your vehicle’s fuse layout diagram to identify a fuse location that is live when the

vehicle is running with the alternator. Key positions in the ignition are typically lock, accessory,

on, and start.

The DC-DC battery chargers feature 50% current limiting from the rated specification when

connecting the LC Terminal to a 12V source. Current Limiting is instant and recommended to

be connected to the same location as the D+ ignition cable. Alternatively, you can toggle

current limiting to your liking by connecting the LC terminal to starter battery positive terminal.

In this fashion, current limiting will always take until removing the LC wire from the battery

terminal to revert to the normal amp rating. Use 18-16AWG copper cable for the LC terminal

and you may need to splice your own connections for the other cable end depending on your

connection point.

You may need to test the fuse location by checking the voltage

with a multi-meter and making sure it’s live only when the vehicle

is in the Start/Run position. This will help in identifying where to

connect if the fuse layout does not have an IGN position. The

easiest connections when splicing can be made when using a

fuse holder splice connector.
