O Scale / Re: Loss of power at track
« on: November 24, 2020, 01:53:56 pm »
I have previously performed all those steps, it didn't resolve my problem.  I put my train on a friend's track with my tw transformer the train still runs slow.  If I use his Lionel 150 watt transformer the train runs really good.  I removed cover off my transformer and checked each connector to case for resistance.  Found wires not grounded.  If I plug in the transformer and measure voltage from pin U to the metal part of case I read 10.3 volts. I  think I should read 0 volts. But I can't find any shorts.  If I had short I believe that the breaker would open.
Any thought
Thanks

O Scale / Loss of power at track
« on: November 23, 2020, 08:46:02 pm »
I have Lionel 736 Berkshire and Lionel tw 175 watt transformer. Just started to operate after many years of not using.  Replaced electrical cord due to rot.  When I run train ( engine, tender, Crane and caboose cars), train does not run as fast as it should.  Measured voltage at pins A and U without train on track I get 18.2 volts. With train on track I only get 13.5 volts.  Does anyone have any suggestion?
Thanks
