Light and brake testing with Drakefield TrailerMaster
Recent additions to diagnostics specialist Drakefield’s product portfolio include its van-mounted TrailerMaster system for testing trailer lights and brakes.
TrailerMaster is designed to enable a single operator to test a trailer’s complete lighting system using the 24n and 24s power sockets, and to test the EBS warning light function on the trailer using the ISO 7638 socket.
Users can connect an air supply from a compressor in order to test the braking system, and test the service brake manually with the service brake switch or via the wired 15m remote control. The system features two glycerin-filled air gauges for service and emergency pressures.
“Connect the 24n and 24s sockets to the trailer then turn on the auto light test switch; the trailer lights will illuminate in a pre-set order for approximately 10 seconds each, allowing you time to check each light,” said Drakefield.
The sequence is as follows: left lights, left indicator, brake light, reverse light, fog light, right indicator, right lights.
The kit is equipped with three five-metre air hoses for yellow line, red line and air supply in; a 15-metre wired remote control for service brake operation; three five-metre electrical leads for 24n, 24s and ISO 7638; red and yellow line coupling adaptors; and a power supply cable (connect to fused 24-volt supply).
