Today we hopefully tackled the last major issue from Mars Trek. At seemingly random the 100 points relay got stuck, which would then happily burn the 100 points score reel coil. A lot of head scratching later we noticed that it only happens for the 1st player, so it's not the 100 points relay, but the end-of-stroke switch in the 1st player's 100s point reel mechanism that unlatches the relay once the score has been awarded.That out of the way the machine finally got to a stage where we started tearing down the playfield for cleaning, repairs and fresh rubbers.#pinball #repair #retrotech #retro
