- Recently Vetus engines have developed a fault where the engine will not turn off, or that the engine is completely dead.
- To resolve this, locate the wiring loom running across the top of the engine and identify a ‘bulge’. Peel back the rubber covering and you will find a block connector, just pull the connection block apart and then put it back together.
- This should rectify the situation. It’s easy when you know what to look for, so spend time scrutinising your engine before a failure occurs.
