    1999 slth ignition update

    I just installed the ignition update on my 99 slth. I put the new stator in and hooked up all the electronics and double checked all the connections. I am not getting any spark. There was twice when I cranked the engine I got a weak spark just as I let go of the start button. My battery voltage while cranking is 11. 5 and it is fully charged. Any input on where I should look next will be appreciated. Thanks

    I am getting 8 volts coming from brown cdi wire when cranking the engine so I guess the hall effect sensors are getting power. I have pushed the bilge button while starting with the same results. While cranking I will not get any spark except as soon as I let off the switch I will get a good spark at the very end. All electronics are brand new. When I replaced the stator and took off the flywheel I dont recall seeing magnets as someone has has said in a previous post. It is possible that the magnets aren't there or in the right spot. I'm not sure how it works but any help would be appreciated.

    If there were loose magnets on the flywheel, I would think you would have noticed when you changed the stator. Check voltage on the cdis red/pur wire when cranking.

    What should the voltage be on the red/purple wire when cranking?

    Could this problem have anything to do with the voltage regulator. I will get a spark as soon as I let go of the start button. I have pushed the bilge button and start button with the same results. Is there a way to diconnect the voltage regulator to see if that is the problem.
