Annu,

Good progress. At this time without knowing exactly how everything is connected it is hard for me to guide you.

You gave good power to the machine. I assume saw and shaper brake on turn off which says brake board is good.

My guess is that the J/P motor contactor is stuck on. It could have happened on it¡¯s own or due to high current of shorted motor but the contactor is suppose to have current sense protection.

Brake board has to be upstream so that it can work with all motors. It is possible that due to bad J/P contactor brake board is getting activated. And when you select J/P things get more complicated because now you have power to the J/P motor.

Just guesses at this point. I think with what you know you should make good progress with felder tech.

keep us posted. good luck.

I made some progress.? So far, i have replaced the brake board and the two CAPS.? I relized i made one mistake.? On the bottom of the electrical box, there are a total of 4 connectors.? There is one for the shaper motor, one for the table saw motor, one for the planer motor, and one that has two wires comming off that go into the general area of the planer/thicknesser.? I'm not sure what those wires are for, but one of them must be for the safety switch on the planer/thicknessor.? When i was doing my different scenarios earlier, i did not have that 4th connector plugged in.? Since that planer safety switch was disconnected, the table saw and shaper did not start up.? So I unplugged the planer motor, and plugged in the other three connectors.? The table saw and shaper now startup without issue.? So the questions i need to figure out are:??

When everything is plugged in like its supposed to be and I turn on the circut breaker
1.? When the machine is table saw or shaper mode, why is the ebrake on the planner activating?
2.? When machine is in planer mode, why is it making a racket going back and forth and surging?? The racket is because the the rollers for thicknesser, which are chain driven, are also surging.

So now, i have 2/4 functions working....I'm getting the bad feeling that there is a electrical short on the planer motor.? I'm still holding out hope that Felder tells me its something simple still.?
Has anyone changed out a motor on a C-31?
