Thanks for that info. I will save that. I learned alot today. The 97 fault had nothing to do with laod weighing.
Fault 97 is Gov Incoder or NTS switch so when you change the menues for 5 yr testing you have to cycle the main line to reset the controler to get out of the test mode.
The reason that wasn't done is a whole other bees nest.
On a 4 car group if i turn off any disconnect the other cars go on fire service, if i turn off the 4th car in the group the lobby security turns off. Any insight appreciated.
