Are the fuses ok ? There are two inline fuses in the loom behind the battery , one 40 amp is the power to the box and a 20 amp that powers the fuel circuit.

Are all the plugs in the loom clean and dry ? Do the pins in the plugs look level and free from corrosion ? Are all the plugs connected ?

If Alt comes up on the display it's either an alternator or fuel fault. To discount the alternator,  simply unplug it and test , if the problem then disappears it would suggest it's at fault.

If there's a fuel blockage then Alt will also appear as a fault code.

However if you now have a dead system then you need to check the 40 amp fuse and then carefully bypass the ignition switch by joining the two wires at the switch together using a blade fuse (i say carefully because if either of these wires goes to earth you can blow the circuit board in the junction box).

If the display is still dead after bypassing the ignition switch then you need to check in the junction box (square white box by the battery) using a multimeter or circuit tester for power at the heavy red wire marked +v using the small black wire in the centre of the board marked 0v as the earth.

Let me know and I'll give you the next steps.

Jase.
