Amber Valley AVSPC10 12v 70A Intelligent Split Charge Voltage Controlled Relay
Part number: AVSPC10
When the engine in running the Charge Guard senses the voltage and allows the charge through the auxiliary battery. When the engine is switched off the Charge Guard senses the voltage drop and separates and isolates both batteries. This means that equipment powered from the auxiliary battery cannot drain the starting battery so there is always sufficient power in the starting battery to start the engine.
Why you need one:-
With todays engine management systems and 'intelligent' alternators you cannot use the charging light on the dash as a switch, also you cannot jump start most new vehicles without the danger of damaging the engine ECU. This unit then becomes cost effective.
No difficult wiring to connect just one wire to earth & one to each battery +ve terminal. (Pin No 1 positive of main starting battery, Pin No 2 positive of Auxiliary / Leisure Battery. Pin No 3 Negative Ground / Earth) Anyone can fit it!
When the engine is running the ‘Charge Guard’ senses the voltage and allows the charge through to the auxiliary battery. When the engine is switched off the ‘Charge Guard’ senses the voltage drop and separates and isolates both batteries. This means that equipment powered from auxiliary batteries cannot drain the starting battery. Problems with flat batteries - Auxiliary equipment draining your starting battery - Fed up with expensive call outs?
