Refer to the Electrical Block Diagram of the two speed Boar Bot on page 24.

Mode of operation

The two speed Boar Bot operates mechanically the same as the single speed
Boar Bot but it also has the added feature of being able to change the speed it travels.
In the single speed Boar Bot the receiver, solenoids, and motors always operate with 24
volts; whereas in the two speed Boar Bot the receiver and solenoids operate with 12
volts and the motors operate at 12 or 24 volts depending on the mode of operation—
Lo speed or Hi speed.
The two switching solenoids have the function of providing 12 volts or 24 volts to
the two electric motors depending on the mode of operation and when traveling in a
forward direction. When the two speed Boar Bot travels in reverse, the speed will
automatically default to Lo speed regardless of the position of the Hi/Lo switch.
Checking voltages on an old two speed Boar Bot

Checking voltages on a two speed Boar Bot

With the two speed Boar Bot in Lo speed operation both batteries are forced to
have the same voltage because of the way the two switching solenoids connect the two
batteries. If the two battery voltages are not the same, then there is a bad connection
between the two batteries. To measure the voltage of each individual battery, one of
the battery terminals has to be disconnected. Once the batteries terminals are
disconnected, measure the voltage across each battery by placing the digital voltmeter
across the battery terminals of each individual battery. Any battery voltage under 12
volts will result in erratic or no operation of the Boar Bot.
In Hi speed operation the battery voltage across both of the batteries (positive
terminal of the rear battery to the negative terminal of the front battery) should be 24
volts.
