When lashing up two P3 engines, when advancing Z4000 throttle to 18V, if I don't wait 40 seconds after turning TIU & Z4000 on, both engines do an uncommanded start. Single P3 engine no problem. Doesn't matter which TIU or Z4000 the lash up is on. This seems to be a signal acquisition problem for P3 engines in a lashup. I'm using the updated 4.30 program. In nearly 95% of the starts, if I wait 40 seconds everything starts okay except one lash up that is unpredictable depending on its location at time of start. Is anyone else having this problem or is it isolated to my layout?
Thanks. Moke Mike
