I'm trying to identify what all the wires are that lead to Bachmann boards. Where the wires come in, you'll see letters like: R, M+, L-, B+, L+, B-, M-, L. I'd like to know what those all mean. Some of them I know:
R: Right Rail
L: Left Rail
M+: Motor positive
M-: Motor negative
L+: Light positive
L-: Light negative
I have found L+/- can be used to designate any light, and doesn't sometimes distinguish between front or rear.
What does B+ and B- stand for?
The boards are marked differently depending on which model you have.
Which locomotive are you working on?
I've got a number of different steam tenders. I was trying to identify the naming pattern (so I can swap out boards as desired).
The board connections are:
R: Right Rail
L: Left Rail
M+: Motor Brush Connected to Right Rail
M-: Motor Brush Connected to Left Rail
L+: Light Positive
L-: Light Negative
B+: Battery Positive*
B-: Battery Negative*
*Some boards allow the addition of a reed switch On/Off controlled battery pack for operation, rather than using track power.
