Testing. (1) With the electrical leads disconnected from the rheostat, connect a multimeter  to  both  outside  terminals. The  resistance  measured  should  not be more than 10% above or below 15 ohms   for   generators   equipped   with old style voltage regulator, 750 ohms for new universal style voltage regulator. (2) Connect  the  multimeter  between  the center    terminal    and    one    outside terminal.     Rotate   the   rheostat   from one   extreme   position   to   the   other. The  resistance  should  vary  smoothly from zero to maximum. d. Installation.  Refer to figures 4-59, 4-61 or 462 and install items  on  the  applicable  model generator set. Change 8  4-73
