I have an older two truck shay. I just had Bachmann service replace the original trucks with the updated ones. I want to install a polarity switch into the loco so I can either change directions or disable to power to it (three way switch). Any suggestions would be appreciated.
Thanks
John
Hi, John.
Some LS locos already have a polarity switch in them. They might have a dead spot in the middle of the polarity switch's throw that would kill the power.
If not, this Radio Shack 275-0664 6 Amp Center-Off switch should work:

If you need wiring instructions, let me know.
Hope this helps.
