Auto Isolator I

Description

• System consists of a controller that detects when a vehicle’s alternator is charging the main battery and then closes a solenoid to tie-in charge to an auxiliary battery
• When the engine is stopped or charge voltage is no longer present, the solenoid opens to isolate the batteries
• Uses a solenoid rather than an isolation diode which typically causes a 0.7 volt drop, thus auxiliary battery receives full charge voltage installation
