Battery won't stay charged overnight


Recommended Posts

Anyone have troubles in this area. Any place to check first. After jump start, runs great, and restarts, but won't hold charge overnight. Don't want to spend a lot of money to have it checked for nothing. Anyone think it may be alternator? Battery is a Mopar, new in 9/03, but disconnected during storage. It ran well for 2 months after reconnecting.

Place a meter in series between positive cable and positive battery terminal. You should have less than .040 amps of current drain. If you don't have a volt meter you could use a small 12 volt bulb and probalbly you will see a bright light if it is drawing down a fully charged battery. This will determine if you have a short.
