Roger's Webasto Test Box
Roger's Webasto Tester Box
Tester Box for Webasto DBW 2010 burners.
Plugs into "B" and "C" plugs in place of the Webasto (silver) control box. Allows operation of motor, fuel solenoid and ignition coil for testing purposes.
You can actually run Webasto with box. Bypasses thermostats and photocell for testing purposes.
Indicator light indicates when 12-volts DC is present.
May vary slightly from photo. These boxes are made one at a time in my shop.
For 12-Volt systems only! 12-volt indicator light is now green.
