Leave the engine in neutral with track voltage at 10-12 volts for 6-7 hours so
the battery can fully recharge (if your engine has a smoke unit, be sure it is
turned off).
•
Use M.T.H.'s battery recharger (Item No. 50-1019)(sold separately) that plugs
into a wall outlet and a special port under the engine 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,
it is time to replace the battery. Available through M.T.H. Parts:
