    The CDI 'computer' has nothing to do with basic electrical power.

    Start with the heavy battery cables. Remove both ends of each battery cable. Clean each cable and connection point, then re-attach.

    Make very sure the engine end of the negative battery cable is a solid and clean metal-to-metal connection.

    Open the electrical box.

    Follow the heavy Red wire from the battery where it enters the electrical box to connect to the start solenoid.

    On the same solenoid stud there should be a smaller red wire. Make sure the thin red wire is on that post, not the other red cable post.

    Confirm that the button on the Reset circuit breaker is pushed down, not popped up.

    Use your multi-meter to confirm you have battery voltage on the red wire going to the circuit breaker, and then the Red/Purple wire that runs from the circuit breaker to the terminal board.

    That would require the CDI to short to ground and trip the Reset breaker.

    The CDI doesn't control power to the start button or the solenoid. The engine should crank, even if the CDI is completely removed.

    On many models with separate Start and Stop buttons, even the LR module can be removed and the engine should still crank.

    Bilge pump should also work, as long as the main Reset button has not tripped.

    Definetly check the ground wire where it attaches to the engine under the pipe!This connection had me running in circles after an engine swap in the sltx! Let us know what you find
