I could use a "tool' like this. I saw a thread on this (or similar) a while back. Am I correct that you (gunrunnerjohn) made this car?
I currently use a "centech" a digital clamp meter I bought from Harbor Freight Re-checking the track voltage; there is a 3 volt drop from where the power supply is connected to the track and the farthest point on the loop.
On one loop there are 6 lighted passenger cars (old ones) I assume this would use some volts.
I am going to replace the 18 gauge wire with 16 gauge,
Thanks for the advice ALL
