    Quoted from LTG:

    The kahr may have been masking a problem that is now worse

    I agree. Remove the kahr and report the results.

    Measuring voltages is definitely the next step.

    Without the kahr board?

    Any burnt pins on J101, especially the 2 red wires?

    I think you mean TP2 is 175mV? Test F113 with a meter to see if it is blown.

    If you do, I suggest cutting the legs close to the body of the BR as possible. Cut 2 legs then you should be able to cut the other 2 legs after bending the BR over to its side a bit. Then you can just heat the cut leads and remove them.

    No. There are many shapes, sizes and different ratings. Get at least 200v 35amp. You can go up higher on the voltage rating, but don't go less than that on either voltage or current rating.
