I have an old Arnold Pacific I got on ebay. When it runs I see blue sparks coming from the front tender truck on the side that if you were standing behind the tender and looking forward would be the right front truck. Any clue as to why it does this? :tb-wacky:
I'm gonna take a wild swing and say that someone put the wheels back into your tender without watching on which side the insulated wheels were. They should all the on the same side, can you check to see if they are?
