Notes
Even if both Battery/Charger are normal, sometimes the red light may not light.
If the light does not work for more than 5 minutes after charging, it means a failure of either Battery or Charger.
Stop charging in such a case, because Charger will be broken too, if you continue using broken Battery.
Differentiating of Charger condition
Measure the voltage between output terminals of Charger with a tester. If you connect it with the nominal voltage source
and the D.C. voltage of 14.4~16.4V is output, the condition of Charger is normal.
As for checking Battery, refer to the technical notice of Battery 122.
Notes in replacing Inlet
When connecting Lead wires with Inlet, as shown in the Figure, connect Red wire to the left side and Black wire to the
right, putting the polar convex in connection cord inserting face downward .
