Main Battery System

A Rotronics main battery voltage monitor is designed to monitor the voltage at the main battery. The unit will flash a red LED and sound an internal buzzer when the main battery falls below 11v (for 12v systems) or 23v (for 24v systems). The monitor can be operated with a control relay kit to disconnect the main battery from the vehicle load circuits.
 
Auxiliary Battery System

Rotronics auxiliary battery monitor and cutout will provide protection against excessive battery voltage discharge. The unit will automatically disconnect accessory equipment from the auxiliary battery when the battery voltage falls below 10.5V (for 12V systems) or 23v (for 24v systems). Batteries will only surface charge if they are flattened below 10 volts and will never charge fully on the vehicle. Australian made.

Rotronics Main and Auxiliary battery control systems will automatically prevent you running your 4WD batteries down.

Engine Monitoring Systems

We have various Rotronics systems available in several combinations to detect high engine temperature, low water and low oil. The monitoring unit self-tests all wiring and sensors and can in turn be wired to activate buzzers, shut down engines to idle or shut down altogether in the event of a fault. Any fault is indicated on the monitoring unit to assist further diagnosis. Our engine rebuilders estimate that a new multi-valve turbo Landcruiser engine would cost $20,000 to fully rebuild if a serious failure occurred. This is an absolute must for outback travel and for industrial use. Again, these are Australian-made. From $377.
