I am rewiring a Mec Brown 415v dual speed cold saw, replacing the
speed change switch, and the Pedrazolli wiring diagram that came with
the new switch doesn't work !!! One speed works ok, the other growls
I have previously proved the motor ok by hard wiring both speeds and
plugging in but I can no longer find the web site where I found the
wiring data. Help !!
The motor has 6 terminals :
"Z - X - Y" on the top row
"U - V - W" on the lower row
I know that for one speed, three terminals are wired together and the
three phase applied to the other three terminal but cannot remember
the other speed's wiring .... help please !
