    Default Bombardier DS650 MSD pn4205

    I have purchase this and I was later told that my tach would not work after install. The early Tachs have a glass lens and funtion fine but the new DS650 tach's have a plastic lense and these do not. ( so I was told). I was told the new tach's dont support square wave?? Is there an adapter I can buy to allow my tach to work with this MSD ignition? 2006 DS650x Baja

    The signal that is produced by the MSD DS650 Ignition is a 12 volt square wave. Most aftermarket tach’s can be adjusted to work. I know on some of the tachs that came on the DS 650’s are nonadjustable. If your tach is nonadjustable an aftermarket tach will be needed.

    Thank you
