I’m struggling! Got a t6175 dynamic with the neutral button in the end of the shuttle lever, it started missing going into neutral so I’ve stripped it down and found a broken wire, we have soldered it together put it back together it worked for ten minutes then stopped. So I stripped down and found another breakage so I’ve followed the wires down to the multi plug in the dash and replaced the full length. Now it won’t work at all! Am I missing something? A fuse maybe?
