Something's not quite right, the hand written report says that the problem is LOW 55v, but the printout says HIGH 55v. The last time that the fault occurred was at 220 hours which, if the timeline is correct, would be after the EMM was changed (if it has been). The EMM should have 4 LEDS, which should all go out in turn with the engine running, if LED 1 is on with the engine running, it would indicate a fault on the 55V side, BUT the engine should be in S.A.F.E. mode. There is a capacitor usually fastened to the trim/tilt relay, make sure the connections to the capacitor are good. If you have the facility to have the capacitor tested, get it done before you spend any money, a knackered capacitor will cause a high 55v fault.
