Steam cleaning an engine compartment is not recommended. All those electrical
connections now have expensive boots and other designs to keep water out. A
steamer overpowers those and puts water and chemicals where they shouldn't be.
With modern electronic systems and multiplexed wiring, the consequences can be
expensive. If it dries out and all the problems go away, you dodged the
As for the battery, you need to put it on a slow charger overnight. The
alternator is a maintainer, not a charger. Go buy a *fully* automatic charger
that has a 2-amp setting and let it charge overnight. Then start it and check
the voltage at the battery terminals. Should be about 13.5 volts (13.2V
minimum) or more with the engine running and the battery charger not connected.
Keep jumping it off and you will have more problems.
