Update on 401 trouble, hey kiwinightstalker I do have a omt manual, the company I work for is owned by Otis. Any way, i replaced the pvt 8 days ago after last breakdown, and no failures yet, iwas going to change cop1 board, but Otis does not have any spares, repair only so I opted for the pvt. Just have to wait and see, thank goodness for the break though as I have been swamped with other intermittent calls. Hopefully it is fixed, or maybe the elevator gods are just giving me a break from this 401 car.
