Right now, I cannot figure out how to get a decent close-up photo to post.

I think I found the answer BUT WITH A BIG CAVEAT: So far in testing, the motor does not continue turning when the engine is lifted from the track - only the lights remain lit.

First all, following Marcus' advice, remember that you are attaching the volt meter reversed, therefore the reading (if you found the negative) should be a plus on the meter reading or face.

Second, after finding the capacitor (in this case on the far end!), solder to the capacitor's contact situated towards the lengthwise centerline of the decoder (not to the contact nearest the edge of the decoder board).

Right now I am making sure that the ACC accelerator has all evaporated before I test further.

Will keep you apprized.

I should have said also that I followed his instructions including turning off the DC feature.

It does, indeed, come with instructions but on attaching it to TCS decoders; not those of other brands. The one I want to attach to is a Bachmann two-function.
I have read Marcus Ammann's instructions but am still having problems.
Glen

It is the TCS KA1. It has two wires: black/white is one; the other is blue.

I cannot figure out where to attach the KeepAlive wires to the decoder in a Bachmann 44 tonner. It has a decoder wired to a light board. BTW, which decoder do I choose in DecoderPro?
