Hello , Im a newbie here and find a lot threads about the edc system but not the problem I have , I bought last month a 1997 fairline sqaudron 55 whit twin volvo tame 122p-b engines , they run great but here s the problem :
Port engine starts up whit key and everything works great from main station , only at upper station it won't shift this might be a calibration issue but to do that I have to solve problem on starboard engine first .
Starboard engine they have removed the main relay out of the box and jumped the switched connections whit a simple jumper switch
behind the starter relay they put in a push button to engage the start motor and pulled out one of the double red wires out and put instead of that a ground to it ( i will go to the boat this afternoon and find out which pins they exactly they swapped out.
this way you have to put ignition on on the dash , switch the jumper they made on the main rely and engine start whit the push button .
runs and shift fine also on upper station only the tach keeps going up and down on lower station , upper its fine .
the diagnostic code it gives is 4.6 and 5.1 (starter and main relay ) when put in original relay s and disconnect the jumper wires it won't work normal
A thing that worry me is a lot of the connectors are all taped together so probably the have damaged the locking mechanism .
I spoke to mechanic that have replaced both edc units (whit updated software ) and rebuild both fuel pumps on engines and when that was done everything worked fine
I hope someone here can help me further as I think it should not be a very big issue as engine start and run just fine but I would love to have it start on the dash and tr to get the shifter on fly get working
thanks in advance
