Hello All.

this has likly been asked before but if i could get an easy yay or nay :-P

All my PF trains have all been converted to 9v, i bought the locos of bricklink with out PF to save the cash. I prefer 9v for myself, the battrys just put me off. One day i might change over but for now i am happy.

First

i want to use 61930c01 Black Electric, Light Unit Power Functions with Black PF Connector Lead

Can this just be plugged onto the top of the 9v motor and away we go.

Is is not all just 9v.

Also can i do this. i may need to reiwre the PF terminal to make it the same as the 9v one.

Idea is to get the 9v power from the old 9v motor and make it run. This is just a cheaper idead to run more than one motor.

It won't work, you need a conversion cable between the PF and 9V train motor (conversion cables have one PF-end, and one 9V/PF end), the 9V/PF-end have to be placed on the 9V motor, the other end connected to the PF-train motor.

For lights you need the conversion cable, too. See this video, lights working from 9V motor:

That's a nice video of your trains but it doesn't show how the PF lights are connected to a 9V motor. For all we know your train may be running on PF.

The 9V system of course had it's own lights. Have a look for them on Bricklink.

I have powered PF lights from a 9v motor. The only problem I've had is that the LEDs flicker off at low speeds (and thus, low voltage). I haven't tried powering a PF motor from a 9v, but I believe many folks have. It will certainly require the conversion cable to take power off of the 9v motor, but on the PF end of it you could then attach both the lights and the PF motor. You may have to turn the PF motor backwards or use a polarity switch though.

Yep. PF lights work great off the 9V motor with a conversion cable. The PF lights seem to be a little more blue than the old 9V light but you can't beat the price and you get 2 lights. I am happy with them on my 9V powered Emerald Night.

This question(s) really belongs in our Question Topic but as there is a discussion, I've left it here in the forum.

"I haven't tried powering a PF motor from a 9v, but I believe many folks have"

this was what i was after also. Sweet time to buy up some bits. as the PF motor about under 50% cheaper than the 9v my 4 9v motors can now become 8 with out a heavy cost.
