extec e7 screener

Hi there,I am hoping someone can help me with a fault in an extec e7 screener year2005, fitted with a deutz engine.When we start the screener, it runs no problem but shows the battery light on control panel and after a few minutes,the engine shuts down still showing battery light on control panel.The altenator has been tested and battery is also good,with test meter showing 14volts approx when running.We have checked all earths and other sensors on engine with everything looking ok.We have found that by switching ignition on and off a few times when engine is running,the light goes out,letting the engine run a good bit longer but still cuts out.Hope somebody can help in solving this problem or where to check for faults, many thanks.

Check the emergency stops. I've had this issue before and found one of the e stops to be messed up. Mine would start and the vibration of the engine would cause it to shut down the battery light will come on if engine is off and key on
