Steve Goodloe Posted March 1, 2007 Share Posted March 1, 2007 I have a Bolex MST motor. I am trying to rig it so it can run off the same battery belt that my SR-1 Runs off of, it is a 12v battery belt so i think it will work. However, i cant figure out what pin is the hot and what one is the ground. I have the old Bolex battery but it doesnt work. I tried the Red for Hot and black for ground but that didn't seem to work. Any ideas? Link to comment Share on other sites More sharing options...
Clive Tobin Posted March 2, 2007 Share Posted March 2, 2007 ...i cant figure out what pin is the hot and what one is the ground. ... With the 7-pin Tuchel: Pin 5 is + (might be red) Pin 2 is -- (might be blue) Pins 1. 3 and 4 go to relay contacts so you can select externally between "12v dc during clapper" and "pilot interrupted during clapper." (Pin 3 is switched -- and ground, 1 & 4 are relay contacts.) Pins 6 and 7 are pilot (might be white and green-yellow) (Pin 6 often grounded) With the 6-pin Tuchel: Pins 1 & 2 are + Pins 4 & 5 are -- Pin 3 pilot ground Pin 6 pilot signal after clapper (Used with the old Nagra III SLO resolver to make a start beep while there was no pilot signal, while playing back the tape.)
