16 Premier Big Boy Steam Locomotive
The two special AA size 1.5v NiCad self-charging batteries recharges continuously
during train operation and should last for up to five years. The batteries are dry battery
that should not leak or cause any damage to your engine. Depending upon when your
engine was built, they may need to be charged right out of the box. If engine sounds
seem distorted or garbled at low voltages or become silent when power from the
transformer is turned off, test the batteries to determine whether they should be
recharged or replaced.
Test:
Put the engine in neutral and leave the track voltage at 10-12 volts (high enough
for the lights to shine brightly and the engine to move steadily) for 15 minutes.
Recharge:
If the sounds are improved at the end of the 15-minute test charge, the
batteries charge has run down and can be recharged. There are a number of ways you can
do this:
•
Leave the engine in neutral with track voltage at 10-12 volts for 6-7 hours so the
batteries can fully recharge (if your engine has a smoke unit, be sure it is turned
off).
•
Use M.T.H.'s battery recharger (sold separately) that plugs into a wall outlet and
a special port under thewater hatch in the tender to recharge the batteries
overnight without leaving it on the track.
Replace
: If the sounds are not improved at the end of the 15-minute test charge, it is
time to replace the batteries. Available through M.T.H. Parts.
DO NOT substitute alkaline batteries for these NiCad batteries. Using alkaline batteries
in this system can result in damamge to the PS 2.0 circuit board and/or the batteries.
**Do not use alkaline batteries for testing or checking purposes for the 3-Volt PS2
boards. Using alkaline batteries will damage the 3-Volt battery charging circuit.**
