My 96 SPX does no want to start, I have a brand new top end and carbs have been rebuilt. I took it out once and it bogged because I had tested the rectifier and it was around 18 - 19 volts. So ordered a new one and replaced, i was their already bought a new starter solenoid and replaced both. Now the ski doesn't want to run, i have fuel (removed the plugs and cranked), it shows sign of spark, it cranks just isn't starting. Also with a full battery the low battery light is on. Can anyone help?
