The camera looks good but it doesn´t work. I replace the 15A fuse but don´t work (the fuse work)
I plug a standard 12v. 4Ah battery with XLR4 plug. I´m not familiar with this cam but I think that it uses standard XLR4 batteries.
Cut and Pasted from a current thread on cml-ac. This might be of some help.
>trying to determine a power/electronic problem with an Arri 35-III.
the camera motor turns on at high speed when the 12->11pin power cable is
plugged in from the Sony XC-77 video tap to the body. This is without the
old style (Arri?) speed base attached.
This is my first post, so by way of introduction, I live in NZ and make
part of my income from looking after the electronics of cameras.
The body of a 35-III is electrically isolated from the battery power
circuit. The transistor (T1 BD249) that directly controls the motor current
is mounted to the body for heat sinking, but insulated from it by an
insulating washer & insulating bush around the screw. If this insulation
should fail, the camera will run quite normally so long as the camera is
not connected to anything else. However, most video assist cameras connect
the power -ve to their body. When they are mounted on the Arri that also
connects the Arri body to -ve. If the above insulation has failed that will
then allow the motor current to bypass the transistor and the motor will
run at high speed. As a preliminary test, with the camera not connected to
anything else, unscrew the 6 pin motor plug. Using an ohmmeter, check
whether there is any continuity between pin 4 and bare metal on the body.
Then check pin 3 to the body. There should be no current path for either pin.
I'm not familiar with an Arri base so can't offer any help there.
Hope this helps.
