hi i recently had the problem of the aux socket falling out of its holder whilst towing resulting in the socket broken up. i had no battery electrics as the wires had earthed out blowing the yellow blade fuse. i replaced the fuse and the battery indicator went to quarter the way across. this weekend i had nothing registering but thought the battery would charge up off the mains hookup.got battery tested at work and its knackered.im going to get a new one fitted but am worried that there could be a prob of no feed from mains charging to battery resulting in another flat bat.are there any things i can check to see if blown anywhere or how to check ive got a charge going to the battery. many thanks steve ps vans a 93 challenger 510
