Motor encoder? Easy to ding when doing the mod if not careful. The plug ports are an easy test as the two stock ones are interchangeable and just plug onto the controller board.

This is one of the many benefits of Gary Bennett's replacement cable kits, you get more than just new bullet proof external cables and connectors.




This is actually how I got into this mess.
I did the cable mod myself...must have gotten a wire or two crossed, and down came my mount. has not worked right since.
I have replaced/repaired everything back to STOCK condition just because I could not find the fault in my wiring(and actually, there may have never been one. it just happened that my mount decided to develop issues precisely at the same time as when I performed the cable mod..)..






You have to be very careful with the cable mod. There are some boards in some mounts that are mislabeled so that the connections indicated on one side of the board are different than the markings on the other side of the board. If you use the markings on the wrong side of the board, you fry the motor board. Even I have done this. You have to look at Gary's instructions in regards to the two different boards and determine which one you have and then be very careful to wire it correctly.

I didn't realize that you had done the cable mod. If the problems started occurring right after the mod, then it is likely that you fried the motor board and will have to replace it.




See the pictures attached: this is the mislabelling on the boards, causing my boards to end in blue smoke. Terrible!

Note to self: Look at the *front* of the board when deciding which side to connect which harness to.

Regards,

Jim

You're right ...

The problem with the CGE boards: after installation in the column, only the back side is visible. Excactly there is where I made 'my' mistake (actually, a Celestron mistake). Waiting for a new board took months and months (as I'm living in Europe, I do not have access to the Celestron spare parts web shop (only assible by US citizens).

Good grief. I never heard about the mislabeling on the boards. Makes me glad that when I switched out my board I didn't pay attention to the labels, I just switched one cable at a time from the old board to the new board to make sure they went into the same sockets.
