Please help newbie. I purchased a 1997 seadoo spx from friend of my brother in law. Told me it ran fine last season but starter went out. I purchased a new starter, new battery. I put lanyard on, nothing, no beeps. I checked fuses and found 5 amp in front box blown. I replaced still nothing. I can bridge solenoid with screwdrivers and starter is turning over but won't start.
