Testing continuity between pickup rollers on locomotive?

Paul KallusOGR Forum Member

I suspect my newer MTH bipolar locomotive (has two pickup rollers) has a disconnected pickup roller (all wires that I can see are attached) because it is stalling on each and every Ross switch (I have another MTH bipolar that makes it through just fine and from operating previous bipolars I know they can make it through. I have a Cen-Tech digital voltmeter from Harbor Freight. If I test the continuity by placing the leads on each pickup roller, it should read close to zero Ohms, right? Would that conclude that both pickup rollers are connected and therefore rule out one of them as the problem? If so, that would clue me to that its a grounding wheel(s) problem. Do I have that about right?
