Lionel 1033 Transformer Issue
Rick has O scale and writes:
“My transformer Lionel 1033 voltage is low when the load is applied it reads 6v. Without load, it reads 18v. I put a jumper from the b post to the circuit breaker but the voltage read only 8v. Any suggestions on how to get the voltage up to 18 or what to check?”
Hi Rick
Check to see if the U terminal goes out to the center rail
rail. If it does, good. Check out the breaker, if okay, check out the voltage control inside the transformer housing.
Good luck.

A transformer’s output voltage decreases as its output current increases. A small drop (eg 10-15%) is normal.
If there is a large voltage drop, you may be taking too much current, or have a wrong connection, or there may be a wire short circuited somewhere.
You have not indicated as to how many locos you are running as that determines the load on the PS. 18 volts to 6 volts is a very sizable drop. Like mentioned in the above posts, unless you have a short or you are overloading the PS, this should not happen.
