Broken power on/off switch

Your vehicle does not have a fuel cut off switch like past ford vehicles , has relay's and a fuel pump control module .

try unplugging each set of leads 1 set at a time,and after each set of leads are unplugged switch it on as it may be a set of faulty leads,it sounds like the safety cut out is coming on and switching off the power to save your system blowing due to bad or broken phono leads or speaker cables.it could also be that you could have blown your output transisters or something else thats causing the saftey cut out to cut off the power,also make sure there are no loose connections inside your mains plug as this would cause the same thing.

What is the model number of your unit?

I have a 2.4 diesel 375 nm model and i have been told that the problem is solved by installing the correct fuel filter. Mine loses all power and stops, and the curly light comes on, and I switch it off and start it again. It works every time but is bloody dangerous on a hill when passing someone and towing a trailer.

try to find the manual , these units have a pre program set from the factory, dissconect the unit at the generator 1)battery terminal 2)main switch on generator 3) reconnect battery and turn on the switch,press auto,should reset

if it comes with a fuel cervo try replacing it... it may be a big help

you should have 2 fuses undere the steering wheel and might be taped to the steering columb this is the most likely cause. good luck, yours should be the same as mine mines a 54 plate

Check for broken wire(s) in the harness at the bottom of the front door (near hinge) where it transits from the inside of door to the lower motor compartment. (Design defect causes metal to cut the harness)

first you are definitly going to need a: razor saw, lead from a resistor, a solder and iron and long nose pliers

then...Using the razor saw cut at a shallow angle on either side of the power socket then continue the cut onto the bottom of the laptop, cut there at a shallow angle. The cuts should be about 1-1.5 inches long and just through the plastic body.

Now cut back and forth between the cuts at the transition point to produce two separate tabs

Snap off the tabs to give you access to the socket. De solder the socket and take it out. check to see if any of the pins are broken....once thats done then solder the socket back into place and test it. or you can just completly replace the socket.. then secure it with superglue.
