GGG posted:The B unit has a slave board (DCRU) which is similar but a little different then the PS-1 bottom board. Additionally this engine will have a larger load than a normal 1 motor steam, or 2 motor diesel. At 6.5V trying to provide 3 to 4 plus amps to drive all the lights, smoke and sounds, 4 motor is probably drooping Voltage much more than 6.5V. Do you have an actual AC Volt meter on the track?
I would also say why try to run at this low voltage? It is not a switcher.
It would be like putting a car in 4th gear up a hill and trying to idle up the hdhill. G
We'll let me put it to you this way - the goal is NOT to starve the train of voltage. I was just giving you a reference based on the ZW notches. I have a DL-109/110 A-B set that work in a similar fashion. Both units powers with master/slave from 1999z This set works smoothly with no dropout into reset ever, no matter what the footage is.
i have no comfirmed that this symptom takes places even all the way up to 11.5 volts of steady running, and that's not even prototypical low speed anymore, that's haulin' ***....and boom, still drops out. Check out my video. This is not normal..:
hope soemone knows what's going on....
