QuestionAfternoon John, Wondering if you could suggest what problem is please? Driving along in my 10 year Land Rover serviced Defender, the engine will just cut without warning, whether driving fast or slow or hot or cold engine. The battery light comes on and the power steering naturally goes off and I just have to pull off the road where I can.
I wait about 10 minutes then I can restart the engine and pull away, as though nothing happened. The next time it happens might be 80 miles later or even more.
It has just had a full service and belt change but it was happening before and continues to happen now.
Any suggestions would be appreciated as my Land Rover dealers don't know what it is and are stumped.
Thanks
David
AnswerThe most efficient way to solve this problem is going to be to attach a test light circuit to the power circuits that run the engine and watch to see if loss of electrical power coincides with engine shutoff.
Start with the engine's pump solenoid, the ECU power, the ignition switch output, etc. Refer to the wiring book and set up tests that you can monitor as you drive.
The dealer can't really do much more for you because intermittent cut out problems like this rarely set fault codes as the computer can't distnguish a loss of power from a fault from a loss of power due to the driver switching the key off.
