I have the K-Line PRSL 15" Interurbans. The powered unit is K2780-6781. The instructions in the box are for K-Line Diesel locos. I assume the electronics are the same, so they just put these instructions in the box. I run conventional. The sounds are Lionel RailSounds.
There is a switch on the bottom with with two choices: parallel or series. What are these settings for?
The instructions say that one can install a 9v battery, but I can find no connections inside
the car for that. Is that not an option for this car?
Does anyone else have this car? Any suggestions on operation?
I don’t know that car; but the series-parallel switch sure seems like it gives you a choice of wiring the motors in series or parallel. This would optimize it for slow-speed or high-speed operation, respectively. (Real locomotives also have this capability–it’s called “transition”.)
K-Line wired a lot of stuff for future up-dates that never happened, like the battery wire or adapter or the instructions cover up to five differant versions of a production run for the reverse units and instructions are for those that have all the features and not just one or two features.
I have a K-Line GG-1 that has the wiring harness for TMCC update but would cost too much to be cost effective for me to have TMCC put in at this time.
