    I think in the thermostat housing on the B, maybe the head. Think it has a red top IIRC.
    Any idea @wore out @Oxbow

    This guy spammed the entire forum to ask his question.
    On a Pete with a B the temp guage and fan switch are in thermostat housing


    The Kysor switch is center of the head on right side
    Low water switch runs light and buzzer in in too radiator tank

    I'm working on a FLD. the temp gauge is in the middle of the head.
    the water level is in the radiator, driver side.

    BUT
    where is the alarmstat located?
