    99 1050 Coil work on 97??

    Does anybody know will a 99 1050 coil work on a 97 1050. I see that they have different part numbers. I believe that I'm looking to part # 4060153.

    As long as I'm asking would the 99 cdi be the same as the 97?

    Thank

    Welcome!

    I don't know if the 1999 ignition coil would work with your 1997 CDI.

    I think Polaris did some upgrading of the ignition system from the first release in 1996-1997 to the 1998-1999 years.

    Later on they released the Ignition System Update Kits for all domestic engines from 1996-1999. This implies that all the original domestic engine ignition systems had reliability issues.

    Has your coil tested bad?

    Do you know if your engine has the original ignition system, or the update kit installed?

    What is the part number on the CDI?
    (check front and back, sometimes there is a second number hand written)

    I'm doing an engine swap, the 1050 into my 96 slx. After purchasing the engine it turned out to be a 97-98. I did the upgrade kit part # 2873091. So it is now the latest.

    I didn't realize at first that the coils where different, so basically they probably are not bad, just wrong thats all..

    Welcome to Green Hulk !

    The 97 & 99 coils are wired the same,Ohm spec's in service maual are the same.
    The original 97 coil has the plug wires part of the coil ( I don't think they are removable ?)
    Starting in 99,it appears the plug wires are replaceable ( you can unplug them from the coil )
    I never switched one out,but I think it will work as long as you have the plug wires with the 99 coil

    As far as the CDI,like K447 mentioned,you need both of the CDI part #'s.

    Oh Hey thanks. Looks to be a pretty good site.

    I seen that difference, (the wires) could this be the only difference??

    Maybe Uh?

    As far as the cdi I will have to look that Up. The new engine didn't come with the CDI but after the upgrade kit I now have an extra magnito.

    Soneone on ebay has the coil and cdi from a 99, and was just possibly trying to make a set 99 cdi with 98 magnito..

    I am confused

    Let me get this straight...

    You have a 1997/1998 1050 motor, that you put into a 1996 SLX hull. That would be a 1996 SLX 780 - a Fuji engine hull - correct?

    And you have installed the Update Kit 2873091 into the 1997/8 motor?
    What year exactly is this engine?

    And you have a magneto left over? Did you install the Update Kit 4010403 magneto into the 1997/8 engine?

    What makes you think the coil is bad?

    BTW, there were two different spark plug wiring patterns for some of these coils (3-2-1 vs. 1-3-2), and two different crank shaft firing orders. Sometimes you need to swap the CEN and PTO coil connections (or the plug wires) to get the engine to run correctly.

    You should be able to see the difference between the 2 stators. Old style will have all the fingers covered with windings.
    The new style stator will have 2 or 3 bare aluminum fingers,no windings.The updated CDI will have a serial port (plug) for programing.The different style stators/CDI's will not swap out.

    And you have installed the Update Kit 2873091 into the 1997/8 motor?
    What year exactly is this engine? Yes, not sure the year but had to have a jug bored and they told me it was either a 97/8 do the bore size.

    And you have a magneto left over? Did you install the Update Kit 4010403 magneto into the 1997/8 engine? Yes - the new motor came with original mag. I didn't want to mess with incase there had been an unknown issue so thats why I bought the upgrade kit..

    What makes you think the coil is bad? I'm not sure its bad just that the original 96 slx only has 2 wire coils. Black and black/white. I did not get the 97/8 electrical box, so I'm using the original 96..

    BTW, there were two different spark plug wiring patterns for some of these coils (3-2-1 vs. 1-3-2), and two different crank shaft firing orders. Sometimes you need to swap the CEN and PTO coil connections (or the plug wires) to get the engine to run correctly.
    This is nice to know..

    You are using a Fuji electrical box with a domestic engine

    I would say you should not use the Fuji ignition coil with the domestic CDI. Use the appropriate domestic Ignition coil part number.

    The Fuji engine is quite different in terms of the ignition system.

    Thats really what I'm looking for is the new coil. The problem I'm having is that for some reason I can't find a used 97 domestic coil for sale, but have found a 99.

    Also, I've boughten all of my other parts from babbitsonline and they list a part number for what I'm looking for (4060153) but no pricing for some reason..

    I also think that If the only difference was between 97 and 99 domestic triple coil was the fact of the removeable or replaceable plug wires then that is what I would perfer.

    I think I will take your advice casey67 and just order the newer coil, with obviously the wires to go along with it, if you are correct that the ohms remained the same between the 2 years.

    Thanks
