My machine is a 2000 expedition 425, yea its getting up there in age. Anyway the machine has always ran great until now. The thing puked out as I was riding the other day and wouldnt start back up. I havent been able to get any spark at all. At first I thought a bad coil, replaced that, no dice. To make a long story short, and being the expedition is a 5 speed shift model. I decided to try an pull start it in gear. Well, that worked, to a point. I got it to start up in 4th gear with a pull. And it will run as long as the throttle is at least 3/4th cracked, any less and it will instantly die. So I was thinking the machine has to be spinning at a high rpm for the stator to make enough spark to keep the machine running. Does this make sense, I have not pulled the stator, nor do I want to if I'm wrong in my figuring. Any other ideas on what it could be? Thanks.

 

i dont think its shot if it will get any spark at all. If it was shot it wouldnt run no matter what

 

Best to do stator resistance test,plus the older models had a habit of chunking pieces of flywheel magnets and screwing up the works! IF it is the stator AND you plan on keeping it,I would replace the flywheel also as its a matter of WHEN not IF the magnets fall apart! The old flywheel supercedes to a sealed unit,no more damage!

 

Now I'm really confused. If it isnt the stator, what else would cause the machine to run at high rpm's and not lower ones. Maybe I should have mentioned the battery is shot, but I dont think that matters at all, I have been pull starting it for some time now. And I've always heard the machine will run even with a dead battery, once started. My other guess was the CDI, but once the machine pull started I ruled that out.

 

your machine will run but will start to blow out electrical components..usually light bulbs first. your stator is putting out x amount of volts/amps. if there isnt a battery there to suck up the juice it gets put into the main electrical system...stuff thats supposed to run at 12.5v doesnt do very good when 15+ volts is getting pushed through it
