Let me just say in advance that I have been at the RR hobby since I was a youngster and just recently became a card carrying member of the USA Medicare team, but my intro to scaletrax has not gone well. Usually through the process of elimination I can trace back and find  a simple solution to the common electrical problems such as electrical shorts etc but I am  at my wits end with my current problem. I recently made the decision to build my new layout using MTH Scaletrax mostly because of the low profile more typical of real life rr and the rather inexpensive costs. I am at the stage now where my tracks are all layed out and swicthes in place ( not wired just yet ), and I started to install the ScaleTRax Lock-on ( which consists of a track connection that includes one red wire along with two black wires). Having only ever used the typical Lionel Lockon or the RealRrax lockons the ScaleTrax was alittle different. I spoke to a Train Hobby store in town and he said just double up the two black wire to the transformer and red to red. Since I have approx 12 of these spread throughout my layout decided to head to Lowes and purchase many of the plastic Splice Tap connectors which seem to be easy to install. I ran a two wire 18 guage wire from my MTH terminal which was hooked into my Z400 MTH transformer around my layout and then went about hooking each scaletrax lockon onto the wire using the splice tap connectors. That process , although tedious seemed to be an easy.

My problem is that when I put an engine on the track and powered the z400 up  to make my maiden voyage around my layout, the red overload light came on and nothing from the engine. Since scaletrax and the lockons are new I am looking for some help from anyone on the forum who can help explain in some plain and simple language what I need to look for as a solution. I cleaned all the track, double checked the wire connections and everything seems ok.  After working to install this scaletrax I must say that I am not a fan of the small metal connections on ends of each track. Man it is not as easy as the old tube track. I guess that is the tradeoff for the nice scale look etc.  If anyone can help I would certainly welcome any ideas? Thanks in advance.

Hi Dan,

 

I can sense your frustration.

 

Red light usually means a short is present

 

With the engine OFF the track, do you still get the red light when you crank up the power?

 

My first guess is that you have a switch that has the ends of two rails touching that should not be touching, hence, dead short.

Scaletrax switches have been known to have rail ends touching. There is a post here somewhere that has pics and easy fixes. Perhaps someone can post a link for you. A quick fix is simply to locate the problem area, and take a very small flat head screwdriver and simply "wedge" the rails apart to create a small gap. 

 

I've found that those lockons need to have their tab connectors bent up to ensure proper contact. 

 

Keep us posted.

 

 

 

those metal connectors are actually really durable and provide great connectivity.  i think you have a short somewhere.  Also, you mention the lockon but don't say why you think it is the culprit.  My guess is operator error here.  Scaletrax has issues with the switches, which need tweaking, but not with the metal connectors or the lockon (except I've found it best to superglue those in the track).  I hope you track down your short sooner than later.  Keep us posted.  Good luck. 

The simplest troubleshooting method is to separate the layout in half(disconnect the track) then attempt to power up each half(no need to put an engine on the track). one half should be ok, the other half should have the short. Continue to split the problem section in half till you get it down to a managable size, then it should be evident where and what the problem is.

 

Hope this helps----

Thanks to all for ideas and feedback. I am now at day three and still have no trains running on my new scaletrax layout. I have double checked mostly everything I know how and I am now just scratching my head. Originally I thought it was the splice tap connectors that I used to connect each scaletrax lockon to a power wire that is running to an MTH terminal strip that is connected to my z4000 transformer. I changed out this afternoon all of the splice tap connectors at the end of the scaletrax lockons and interjected the push-in wire connectors. When I power up the transformer I get a little light in the engine like it is not getting enough power and the overload light on the z4000 comes on. Since I am new to scaletrax and there  lockon could the problem be the copper strip on the bottom of the connector to the track. Still looking  for any scaletrac expert advice. I do have 17 switches in the layout that at this point are not wireup but I don't see that as a problem as far as I know.  Any advice?

Tom,  just go head and start your layout. You really shouldn't encounter any problems if you take your time and check your connections for correct polarity along the way. We built a fairly large ScaleTrax layout and had little to no problems over a three year period It's great track.
