Our church has been having issues with the guitar that is used for worship recently. So, they borrowed a guitar but it needed a 9 volt battery for the sound to go through the sound system. So again they found someone who had a rechargeable 9 volt battery. Well, the problem was the battery was not charged and it was 5 minutes before worship time. They did not have the charger either. Now our church is in a small town, so there is no Wal-Mart or really any store open on a Sunday. In my mind that means tough luck we won't be using the guitar, but this is Brazil we are in. Next thing I know the guitarist is asking me to pop the hood of Pastor Ricardo's car and he has the 9 volt in hand with a electrical wire sticking out of the positive side of the battery. That's right he used the car battery to jump start/recharge the 9 volt battery. The battery actually worked after that. He got through 3 out of the 4 songs before it lost its charge again.
I am continually amazed at what they can repair here and how MacGyverish people can become.
