Ok, I got a NOS 6-12944 Sunoco Oil Derrick today and when I bench tested it on the workbench it worked fine. It is from 1997 made in USA. My test bench has a Lionel 1063 75-watt transformer from 1961. So I decided all was good and placed it on my layout.
I use a CW-80 set to 13 watts for accessories and have several accessories on it but most are just LED lights. Feeding with 20-gauge wire.
When I hooked the Derrick up to the CW-80 it would stall and jump and not pump??? I turned off all of the other accessories and it did the same, I turned it up to 15 volts and it did the same??? So I thought I needed to use bigger wire to feed it. Went to a temp jumper of 18 gauge and still the same. Ran a jumper off the ZW track connection with 20 gauge and set to 13 volts and it works great??? So I wired it up on it’s own switch with power from one of the accessory ports of the ZW and it is working fine.
What would cause this difference between the ZW and CW?? Tks,
