deefender 90 has caught a cold i think as the battery doesnt seem to be turning starter over bumped it this morning and fired over in a second but when i left it for a few hours it just gave that continious clicking sound .Theres lights on dash as tho ive got plenty of life but just not enuff to turn her over ive checkedall connections on starter and battery and they are fine.does this mean battery life is over idont know how long its been on as just bought it if i need a new battery whats the best amps i need for her.The one thats on is like a big long wagon battery but dont know if its the proper one thanks lads
