I'm just surpsised no one's done a decoder with a 1.5V lighting output for engines like this.

I asume the NCE decoder drop in still needs resistors.There is so much room when you rip the board out you can put many decoders of choice in these P2K units.The bulbs suck so put LEDS in. Even with a plug and play there is plenty of wire to put resistor in. Uping the light bulb to 12 or 16 volts is going to heat up plastic. Again for sure do the work and add electrical feeders from other side of truck, do not depend on the truck pivot for pick up.............oil grease dirt gets on the pin...........its a weak link.REMEMBER old units came with faulty 8 pin plugs on them, a tracer had tobe cut or it would short and blow a decoder.Its been awhile but this episode is well documented, just google it or maybe a modeler has a link. Remember to the NCE P2K decoder drop in came out long before there were other choices such as TCS. You are far better off to strip her down redo the wireing and hard wire a decoder in it with LEDS.

The NCE site has www.ncecorporation.com/extras/manuals/decoders/p2ksr.pdf and it looks like resistors need to be added to use LEDs or incandescents. From TCS: LL8: "This full featured BEMF decoder with 8 available functions is designed specifically to meet the needs of LifeLike Proto 2000 HO-Scale modelers who are converting their HO-Scale locomotives to DCC. This decoder has a built in voltage dropping circuit for the front and reverse light so there is no need for resistor use with existing 1.5V bulbs. Included is our auto-adjusting BEMF for outstanding slow speed performance and hassle free set up. Also includes Quiet Drive for super quiet engine performance." LL8-LED: "This full featured 8 function BEMF decoder is designed specifically to fit HO Scale LifeLike Proto 2000 Included is our auto-adjusting BEMF for outstanding slow speed performance and hassle free set up. Also includes Quiet Drive for super quiet engine performance. This decoder has a built in voltage dropping circuit for the front and reverse light so there is no need for resistor use with existing LED's. This makes installation in the newer Life Like P2K's with factory LED's a snap!"

Unless I can make the headlights look like those in the more recent runs of Atlas C420s, to my eye bulbs always look better than LEDs. Thanks guys.

I have a fair number of P2K GPs with TCS decoders, some with LEDs I installed. To get them to run with Atlas-Kato units (14:1 gearing), I set CV5 to 220, CV6 to 110. That slows them down enough (12:1 gearing) to run with engines of a slower gear ratio. The CVs give a good starting point, then fine tune as required to get them to run together. The last pair I tuned up would squeal until I took them apart and cleaned the peanut butter out of the trucks.
