seems like some functions work on this mfd an others dont,i can get the code function to work an the red warning light too.reading in the manual it says to unplug the four prong connector to energize the mfd ,also with the battery connected,am ai missing something else?seems like if the mfd didnt work all wouldnt work.just trying to figure if theres something the dealer does to program it that i cant figure out.also this ski has been sitting for a year with a dead battery but the previous owner said it was working fine when it let a piston go.
