Hello all -
I have a very clean 2344 with very little run time. It probably hasn't seen the rails since the late 1950's. After lube and oil service, I applied power, but all I get is the buzz of the e-unit. I took the shell off and can see the pall cycing the drum. I jumped the e-unit with two wires directly to one of the motors, but not even a twitch. What am I missing?
Thanks in advance.

Samplingman,
I had the same problem with a Texas Special f3 2245 single motor, & it ended up being worn down brushes. Remove the shell which you probably have already done, & apply some pressure on the brushes. Just a thought, give it a try.
can you spin the armiture? When i jump my motor it usually take 3 wires. One to brush, one to ground and then connect field to the other brush. If the motors fire then start to sniff around E unit and the wires from E unit
You could also have poor electrical contact in the e-unit.
Sometimes when a loco sits for a very long time, enough oxidation will build up to prevent the e-unit fingers from making contact with the drum. The metal parts may not look dirty, just dull.
I have also run across engines where the wires from the e-unit to the motor terminals appeared to be connected, but were actually broken inside the insulation.
