A fellow brought me an American Flyer 1250 Transformer to check out. He said the power to the track was intermittent. Well it was because the contacts on the end of the transformer were very dirty and not making good electrical contact. He also brought in the lock-on which I recognized as being used on Wide Gauge. After I talked to the owner he brought in the locomotive. It is a 4644 Electric. Bench tested the locomotive with a ZW and the locomotive ran great.
I checked out the transformer taps with the following results:
1 to 2: Should be 5 ½ to 8 volts. I got 7 to 11 ½ volts
1 to 3: Should be 8 ½ to 11 volts. I got 13 ½ to 18 volts
1 to 4: Should be 11 ½ to 14 volts. I got 19.2 to 24.1 volts.
Since I don’t have a lot of experience with American Flyer Wide Gauge, were American Flyer locomotives designed to run at such a low voltage? The max the 1250 was designed to put out was only 14 volts compared to Lionel’s V and Z which were good for 24 volts. If so I presume you can ruin the motor by using a Lionel transformer and not being aware of the voltage. True? I know you can ruin a Marx motor by using too high a voltage.
As to the transformer. The fact that the voltages are much higher than the time plate states leaves me with two questions:
Did American Flyer make another similar transformer but with a higher output so maybe the nameplate is wrong?
Or are some of the windings in the secondary shorted out? I took off the top and it looks like the transformer was too hot at one time.
Your thoughts please and thanks for the help.
