Freezing weather is wreaking havoc.

I'm at a loss about how to fix this, short of driving it to the nearest Delica-friendly shop. Any suggestions?Battery charge warning - usually off when driving. If on (which it should be at
start-up), it shows that the battery is not being charged. If it comes on while
driving it means there is an electrical fault, in battery, alternator, or alternator
drive belt (the belt could be broken or simply slipping). You might be able to
continue driving for some time especially if you can limit the amount of
electrical load.
Fuel filter warning - usually off. If on, there is water that needs to be drained
from the base of the fuel filter.
