Does anyone know how to open up the PDB on a '96 E350? I've got a short that I have traced back, and I think it is in the box. I want to get inside and check everything behind the maxi fuses, but I don't know how to open it up. Help??

 

Most fuse boxes have to be opened up from the rear. They usually have large wiring connectors that are bolted to the rear of the box.

 

There is a large bundle of wires going into the PDB, but no connector that I could see. I was hoping that there was a way to lift up the plastic panel beneath the fuses to access the wiring from the top, but I haven't figured that out yet. I can detach the PDB itself and rotate it 180, but it didn't give me any access from the bottom side.

 

If you look at the wiring at the rear of the box, can you see some bolts or screws buried down inbetween the wiring?

 

Dave,

Per our other thread, I think we have narrowed our issue down to the aux batt relay.

As far as the PDB, I can't get anywhere near those wires. We cut the tape around of them off to see if there was a terminal block that we could unplug, but there isn't, just wires going into the PDB. I could barely get my hand down there with my knife to cut the tape, so I know that I can't get to where I could see into it...but, hopefully I won't need to now.

Thanks for all of your help!
