A friend borrowed my 1993 GTX 580 (bought recently) but failed to replace drain plug, as a result hull filled with water and engine quit. Upon investigation the plug wires were cracked/frayed and suspect that water contacted plug wires (where cracked) and disabled the electrical system. While water injestion was possible/suspected we are not 100% convinced that this actually occured (inside of airbox was dry upon inspection).
On shore the machine cranked but would not start.
Our diagnosis revealed that there was no spark at end of plug wires but there was spark coming into the coil. Therefore we replaced the coil/plug wire set - engine still cranks but will not start. Battery was replaced with new one as cranking eventually drained the old battery and spark plugs are new. A mechanic (primarily snowmobile) checked the stator for spark (checks out ok) and confirmed that all grounds are ok. All fuses checked out ok.
Any one have an idea as to what could be causing this 'no spark' condition? Could it be the module (MPEM) and how can we confirm this (not cheap to replace so don't want to replace it if not needed). I noticed in other messages that if one were to disconnect and re-connect wire on flywheel cover (?) this might affect the no-spark condition - is this worth a try?
Will really appreciate anyone thoughts or suggestions on what we should do to diagnoze and solve this problem.
