Hello Group:
Background:
I am building a trolley layout with "live" overhead (positive). The overhead contact wire is 24 gauge phosphorus bronze wire (standard for O scale). Track is Code 100 steel electrically bonded together (negative).
I am using 16 gauge buss with 20 gauge drops. The drops for the overhead are soldered to 1/4" steel rods which hold up the overhead.
I have over 200 feet of rail installed, but only about 20 feet of overhead installed to this point.
Problem:
I have converted 3 trolley cars to RP using the LM2-S module. The cars move about 3 inches, then stop; move 3 inches more than stop; move 3 inches more than stop etc. Occasionally I receive the fault "low track voltage" but not continuously. The HC-2 shows track voltage at around 13.8 volts. The cars pull less than 1/2 amp. The module always runs cool.
The remaining trolley cars (not yet converted to RP) run flawlessly on DC power.
I want to solve any problems now before I go further with any installation.
Does anyone know what I may be doing incorrectly?
