Reply to "How To: ERR Cruise Commander With Tethered Bridge for 4-Motor Operation"

For the novice like myself, how durable are the pins on an FET? Can they be bent several times as do the removal of the BR and complete the tether?

You can bend them a few times, but it only takes two.  Bent them close to flat to chop up the bridge and install the tether wires, then bend them back.

I'll also short circuit the inevitable comments about "why didn't you remove the original bridge and use it".  I did briefly try a desoldering on the bridge, but when it became apparent that I'd need more heat than I'm comfortable using on a PCB to fully loosen it for removal, I decided to not risk damaging the PCB for a cheap bridge rectifier.  YMMV, but I like my method to minimize the possibility of wrecking a $100 board.

@gunrunnerjohn  Thanks John, is it better to use a thicker washer about the size of the BR top?

The washer has to be smaller than the bridge for obvious reasons, the connections are on the corners!  The washer is really to provide an even pressure to the bottom mounting hole boss instead of relying on the nut that might put pressure on one side and crack the plastic.  I think I used about a 3/8" diameter washer, it was "big enough".
