@JPS posted:Thanks for the tips and suggestions. Part of my befuddlement was due to running a search on YouTube for a video to follow and finding something close but not exactly correct as far as engine type.
I assume to get at the battery in the S-2 I will need to remove the trucks to have access to the body screws.
Is there a way to easily tell what kind of battery I need for a locomotive before I disassemble so I only have to open it once? I understand that there are two different batteries.
Besides two S-2s I have the following locos that I may want to replace the batteries:
Reading 635 30-2425-1
Pennsy 8974 30-2379-0 or maybe 1
Jersey Central FM 2408 30-2928-1
LNE Camelback 153 30-1402-1
Many thanks.
Look at the bottom of the locomotive for the charging port. If it is a round connector with a single pin in the middle it's the old 9v style (8.4 NiMH) battery. If it is a rectangular connector with two pins, it is the newer 2.4 battery pack.
Trucks don't generally come off unless the body is already removed. According to the manual, there should only be two screws and four body clips that need to be pinched to remove the shell from your S-2.
