SM155 Typical Wiring example
The module simply connects between the ‘+’ terminals of both batteries via a heavy duty cable and an earth cable is connected to the vehicle chassis.
The Yellow wire can be used to supply vehicle accessories (Radio, GPS etc.) that would normally flatten the vehicle battery if left on for extended periods.
Two LED indicators show when the Battery Linking is active and when the Auxiliary Timer is active. Two more indicators show when the manual override for these features have been engaged. (The Manual Override controls will automatically disengage the next time the vehicle is started. This prevents the output from being latched on indefinitely.)
