F-3 A B A DIESEL ENGINE SET
The special NiCad 7-cell 8.4v self-charging battery recharges
continuously during train operartion and should last for up to five years. The battery is
a dry battery that should not leak or cause any damage to your engine. Depending
upon when your engine was built, it 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 battery to determined whether it should be
recharged.
Test:
Put the engine in neutral and leave the track volt-
age
at 10-12 volts (high enough or the lights to shine bright-
ly 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 battery 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 battery can fully recharge. If your unit has a smoke
unit,
be sure that it is turned off
.
Use M.T.H. s battery recharger (sold separately) that plugs into the wall outlet and
a special port under the engine
(see figure 10)
to recharge the battery overnight without
leaving it on the track.
Replace:
If the sounds are not improved at the end of the 15 minute test charge, the
battery must be replaced (as shown in figure 11, below). Contact the M.T.H. Parts
Department (phone: 410-381-2580; e-mail: [email protected]; mail: 7020
