Hi guys,
I have a friend who has recently bought a boat with a not running 2005 etec 75.
On first inspection the main 10a fuse was blown, we replaced this and it blew immediately.
I unplugged the J2 connector and we can now power up the EMM and communicate with ev Diag.
It appears as though the emm was over heated as that is the bulk of the faults evident.
Firstly.i am wondering if someone could describe the process for performing an emm recovery so I can get the injector coefficients.
And secondly what part number EMM would work ? The part number on the emm is 586759c but these are proving very hard to come by in Australia

586759 is the current part number for the correct EMM. I do not have a way to look for any older part numbers that may work.
Anytime EV5 is connected to an engine a copy of the Engine Data File is saved in the Exports - EDF folder. This contains all of the engine information which can be loaded to a new/replacement EMM. The numbers for the injectors should also be listed in the engine report.
As I recall EMM recover can be selected in one of the EV5 drop down menus, but it has to be done before you got the "connect" button. This will only reload the programing inside the EMM and will not fix an internal short that is blowing the fuse.

not an expert but… by disconnecting J2 it seems several  external components   are  "removed" from the EMM      which themselves could cause some grief… possibly   blow a fuse  ??

 have you  tried to check the wiring and assoc. components   on the connector side  of things to see if any  could cause    that fuse to blow.  

 
ex: bad/shorted condenser,  55v wiring to the oil injection pump etc...   

wiring info is somewhat limited  but after you have secured the  necessary info from the EMM  for your next EMM load   maybe you can  poke around to see  if the  problem is external to the EMM


  wiring file picture  is 27mbs so impossible to load here

With very little doubt, the EMM will be found defective.
