Schaudt Elektroblock DP02

The DP02 is a D+ interface and booster unit that is usualy connected to Block 2 of an EBL unit.  It is typically fitted to larger motorhomes that have a lot of load on the D+ (Engine Run) signal.

These units often fail internally and prevent the EBL detecting that the engine is running.  Typical symptoms are lack of step retract on engine start, no fridge operation when driving and no split charge operation.
