Hi Guys,
My layout has been "tracked" and wired.....about 200 feet of track. All my engines that have 4-wheel trucks, like RS-3's and RS-1's, run perfectly, even at full throttle....I should mention that I'm using old-fashioned DC technology with Aristo-Craft walk-around radio throttles. When I place an engine with 6-wheel trucks, like a DL109, they start to move and then I hear a click in my Aristo-Craft receiver, indicating there is a temporary short, then the engine moves a little further, about an inch or two and shorts out again. If I start the engine very, very slowly and power it up ever so gently, it doesn't short.

I've checked the wheel spacing on the DL109 and it is fine. I've been in this hobby for over 25 years and have had 3 DC layouts, all using the Aristo-Craft throttles and this has never happened before.

Does anybody have an idea as to what is happening?

Thanks in advance for any ideas you can offer.

Maybe someone who has used the Aristo controller
would have more pertinent information. I don't
know anything about it.

However, two things come to mind. Do your
6 wheel truck locos draw appreciably more power
than your smaller locos? A multimeter set to amps in series
with one track lead from the power pack would
tell you. Does the Aristo breaker have a sensitivity
control?

I found this discussion thread on line. It may help.

You didn't describe the track situation where the
loco shorts. Was it a straight away, serious curve,
turnout or the start of an elevation?

Hello Don,
First of all, thank you for considering my question. To answer a couple of your questions.

The short occurs both on straight and curved track. My curves are wide anyway and have easements built in, so I don't think that is the problem.

The Aristo-Craft controller does not have a sensitivity control.

I'm not sure I understand your suggestion to use a multimeter, which I have. Could you clarify?

Thank you again,
Mondo
