    3657 starter solenoid
     
    3-terminal with insulated base. Notice the battery cable stud is identified. That is because the magnetic coil is powered by the battery stud internally. The ignition switch grounds the small terminal to activate the solenoid.
     
    A suitable replacement would be a 4-terminal solenoid with an insulated base with a jumper from the battery cable stud to one of the small coil terminals. The other small terminal is grounded to activate the solenoid.

    3656 3-terminal ignition switch for magneto ignition and electric start
    No battery power to this switch. The switch grounds the ignition and starter circuits to control them.
     
    The 3656 was originally a single wire switch but part number changed to 6890

    Gage Tachometer 113467 113476 78-0060

    Suspect the 113476 is a typo and should be 113467
     
    113467 replaced by 78-0060

    Mistake in 492-4509 manual - The 113476 and 78-0060 tachometer does not get it's signal on the grey wire from the B+ terminal of the voltage regulator. This is also incorrect on page 3-10 describing the tachometer's operation.
    The grey wire comes from one of the regulator's AC terminals. If the tach will not work try the other AC terminal. Only one of them has a tach signal.

    Common relay 98-7249
    Used on 1999 312-8 model 73429
    Notice there is a diode or resistor across the coil terminals as illustrated on the relay cover so the polarity of 85 and 86 is important.
    85 should be 12VDC +
