Problem with 2-6-6-2

[Peter Webster]

My 2-6-6-2 is having trouble with the transferring power from the tender to the loco. When I put it on the track it makes a chuff sound but all other functions do not respond.
I have noticed that the large plug from the tender that plugs into the loco at the rear is a loose fit so could this be the problem. I have run the loco about twice on previous occasions and all was well.
Can someone help me please or should I return it to Bachmann for repair.
Thanks

Hi Peter
if i'm not mistaken is the big connector for the motor and the lighting.
The small one is for the track pickup.
My experience with the connectors is that the part on the pcb underneath the cab is prown to breaking of from the copper leads on the pcb.
If you have no experience with soldering small parts don't even think about fixing it yourself.
