Just set up our 20 year old LGB starter kit again this year, with added track (~40'). The 5003/110 transformer stops putting out its typical 14 volts after 30 minutes of use. No volts showing at transformer spring-loaded terminals. After a "cool down" period, its back up and running, then stops again, but in a shorter time frame. The spring-loaded terminals are tight. Is the engine motor causing the malfunction?
Kids are coming over tomorrow. Help!
