Good afternoon forum members:
I would like someone to explain to me what the functions are for three (3) different circuit boards found in an O Gauge RailKing 4-6-6-4 "Challenger" (30-1818-1)
I have gone onto the new MTH parts site and located the electronics for my "Challenger", and the site lists three (3) different boards:
1) PS3 Boiler FET Board - EMI Compliant (#18 on the parts list)
2) PS3 Boiler Relay Board - Non EMI Compliant (#19 on the parts list)
3) PS3 / O GAUGE STEAM / TENDER (UNIVERSAL) / W/SUPER CAPS / EMI COMPLIANT (#20 on the parts list)
I think I have a "dodgy" main board (see my post on trying to do a factory reset on my PS3 Challenger using my Z 750 transformer) and I have ordered one from MTH and put it on my "wish list", as it is out of stock at the moment. Thanks for the tip Mike!!!
Question: Should I purchase all three (3) circuit boards, or should replacing just the main board fix all of my problems? I purchased this loco through the Cabin Fever MTH Warehouse Auction - see handwritten note on the box.
