Can anybody give some advise? I can start my car in the morning,everything is good. However,when I shut it off,say to go in the store,crank it to go home the battery light stays on. The alt. gauge shows a charge but the light is on. Let it sit til the next day or a few hrs. and it's good as new. Also,if I don't drive it for 3-5 days I have to put a charger on itbecause the batt. is dead. Just bought a new batt.so I'm thinking a relay might be sticking....???? Any help is appreciated.
