On page 2 of On30, there is a thread on Currnt Keepers for the Shay.  There are 3 different Links listed on that thread with more info on adding Keep Alives for various decoders and locos.

Many times the positive will be the blue light wire, but NOT on the Porter.  If you can find the positive and neg points on the bridge rectifiers, those could work.  Marcus Amman's Main North web page also has a lot of info on adding keep Alives to many decoders, plus some theory!  I never felt the need to add keep alive to my Heisler, since it almost never stalls.

Hello Reg,

Any chance you have a direct URL?

I hit my search engine and came up with this, which seemed to be the obvious home page:

http://mainnorth.blogspot.com/

I went thru all the links/year expansions, but if I had the correct site, I wasn't able to locate the referenced information.

thanks,

Jerry
