HO Baldwin 4-6-0 82302 motor low resistance

Can someone please confirm what the motor resistance should be?  I have about 5 ohms which seems far too low and the running current is about 1A! But it runs ok in spite of this.

With thanks

Not stall current - please read my post again (I did specify RUNNING current), I wanted the DC resistance of the motor as I measured mine at 5ohms.

Lubrication will NOT help - having now removed the motor I can see a heap of black gunk around the commutator (after only about 1 hour's running or less).  Someone at the factory seems to have drowned it in oil and the conductive gunk, a mixture of dry oil and carbon, is clearly (maybe not the best word here) a good conductor.  A poor advertisement for what should have been Bachmann's upper quality loco.

Hope you other users do not have the same problem...

I'm not an electrician or a geek.  But if this is a DCC engine, cv 2 controls the starting voltage, maybe this helps.
