Z4000 overload issue

darkmarcOGR Forum Member

Does anyone know how many amps the MTH Z4000 transformer can handle? The Z4000 overloads, causing the blinking red overload indicator light when an engine is pulling more than 10amps on an uphill run on my layout. I have an MTH 4-6-6-4 Challenger, and it pulls more than 10 amps hauling just 4 passenger cars up a 2.5% grade, causing the transformer to indicate an overload, which then shuts off the entire layout. It seems to me the Challenger should be able to pull many more cars that four without overloading the transformer.

Any help would be appreciated on this issue.

Thanks!
