Yes, pull the battery and have it thoroughly tested. If it checks out fine, the next step is to check for a parasitic load that is killing it while it sits in the garage. Your voltmeter is probably capable of measuring milliamperes, or you can pick up an inductive DC amp gauge if you want (see this thread for the one I use: 300 amp X 12 volt Circuit breaker ). If the battery is strong, and there is no parasitic loss, we'll move on to the next step. |
