Hello everyone, really need some help here. I aquired a Genesis SP MT4 4-8-2 off of eBay sometime back for a really good price. The reason I got the locomotive dirt-cheap was due to the fact that the tender was missing... I managed to hunt down a replacement tender at a hobby shop and it's on my workbench right now. The issue is that the tender is basic DC and I need to know what the sequence is for the 6-pin plug i.e. track power left, track power right, motor +, motor -, headlamp + and numberboards +. I understand that Athearn uses a frame ground for the return - current. Any assistance would be most appreciated and thanks in advance. John
