No lights
The mains supply is not reaching the charger, check that the mains is working, that the mains plug and fuse are in correct working order. Otherwise consult: Sunrise Medical or your local Sunrise Medical dealer.
Flashing lights

Consult Sunrise Medical or your local Sunrise Medical dealer. The charger has a designed in safety feature which prevents it from commencing to charge if the battery voltage is lower than
16 volts for a 24 volt battery. This low voltage battery condition is usually the result of very deep discharge or totally worn out batteries.
Yellow mains on light only
Disconnect the mains supply. If still lit, the battery has been connected the wrong way round. Check all connections to the battery terminals are the correct way round.
If the light goes out, the battery is not properly connected or may be flat. Check the integrity of the battery connections and consult Sunrise Medical or your local Sunrise Medical dealer.
