Honda cr-v won't start?

I have a 2002 Honda CRV-EX that has refused to start for my wife.?

• My wife took our 2003 CRV out for a drive recently, she went about 20 miles, stopped at a local store. She came out about 10 minutes later, try to start the vehicle but it would not go. She got a jump start which got her going, the person who jump started the vehicle checked the battery with a voltage meter. He told my wife that the battery wasn't charging, he suggested a new battery. She and I have both started the vehicle since that break down successfully. My wife has said that sometimes the radio losses the station when she goes over a bump, I think that there is a wire loose somewhere in the ignition-starter system. I will take it to our Honda shop near by but I am curious about the possible cause of this situation. I read in the owner's manual that other metal keys or metal wires near the ignition key can effect starting.

• Answer:

  Understand the the battery stores voltage, The alt generate elect. The car accually runs off the alt. That is why with the car running if you remove the +bat terminal and the car dies the alt is bad. It would indicate the car is running off of stored elect in the battery. Did that make sense. Next for the other issues. I have found that the majority of elec problems come down to a dirty, loose ground connections, broken wire or a shorted wire to ground. Because the radio acts up on bumps i would spend the time to check all common ground frist. Neg Bat to gropund (cable). Engine to frame, and some cases body to frame. I`m thinking this will resolve the issue. Have fun day.
