Hello Dear People

 

I have just received an Arri 16 BL with a crystal motor which I can not recognize.(pic attached)

 

Having trouble to operate the camera as the motor is acting weird...i have an XLR4 12V battery for this cam as recommended. When I plugged it on the power the camera started to "cough" and cogging which I found weird...then I found that I could actually change some connectivity or circuit manually swapping a little 6 pin square plate at the back of the motor (see picture with the rods removed) and after that as soon as I plugged the camera on power the motor kept running on 50+ speed all the time without me switching on or off, nonstop and I can not even change the frame/sec at all...could anyone help me what is this as I honestly have not seen anything like that...thank you!

It kinda looks like the Arri-made motor control called the BLEQ.

 

Unfortunately, I know little else about this motor.

I would give Axel Broda a call - he's the best Arri technician in the entire world - and one of the few who still works on the 16BL.

I went inside the motor area on the Arri. The motor itself looks pristine but the connector to the BLEQ panel looks like this....am i right sayn that isn't normal right? looks like some cable overheating.....i didnt know that the actual motor and the BLEQ panel are two separate thing so I am suspecting something going wrong on the panel and not in the motor. 

 

Any suggestion? I talking about this and discover this rare beauty. 

 

Cheers

Looks like some corrosion and a wire may be broken.

Try dismantling the plug, cleaning it up and re-soldering. Check continuity with a multimeter before and after.

If you're not handy with a soldering iron, it will have to go to someone who is. Or you could acquire a new skill.
