Question Behr aircon issues in 65' 300se

Hi Folks,

I'm hoping someone somewhere has the same Behr aircon unit that I have in my W112 300se coupe. I've been restoring the unit over the last few years and I'm almost there (I think)

My issue at the moment, is that whenever I turn the unit on when the car is running it blows the 5th fuse in the engine bay, the one which controls the indicators. But the aircon unit continues to work properly. I'm just without my indicators. The ac unit is not gassed as yet so I dont know if it's cold. But it blows!

Does anyone know why this could be? Or what I could do to try and diagnose/isolate the problem. I'm using a 15Amp fuse as has always been used.

Also, if anyone has instructions on how the aircon unit works I would be really grateful. I guess I will work it out when the unit is gassed and working, but I'm just one of those people who likes to know how something works as much as possible.

I've attached a picture of the unit.
