Hiya...if your battery need attention to charge it up, I suggest a very good, modern battery charger from well-known stores such as Sears, Canadian Tire or what's available in your town.
The newer battery chargers offer smart-charging technology to provide correct polarization and 12 volts/amperage for 'instant boost' power/quick charge/overnight/slow-charge functions that you select it and the beauty of it is the 'smart' charger slow down the charge voltage to a trickle to prevent 'cooking' of the battery cells (so the battery case don't expand and crack/leak acid)


Tip: if your battery received a 'instant boost' prior to driving off, try driving around for at least 15 minutes to allow the alternator to pump full charge to the battery so it should store enough 12v power in it for your next start-up.

you dont know where the dimmer is? on the left, on the headlamp switch or a small knob.

the battery wont stay charged? if youre putting in a fully charged battery and your car runs, but then the battery slowly dies, the problem will be your alternator. the alternator is what maintains a car batteries charge. try replacing the alternator. hope this helps.

SOURCE: Battery won't stay charged, it is brand new battery, alternator has been checked and it is good, blown BTN 60 watt fuse, on 1994 Mazda Protege.

The 60amp fuse probably is in the circuit between the alternator and the battery. Which would be why the battery is not getting charged.
Someone would need to check for a short in the wiring between the alternator and the battery.
