My 2010 Mazda 6 was running fine but when braking, the Radio, AC, and wipers went out...it was driven home and after shutting the engine off, it would not start at all (battery was good ) ... When trying to start it again, all the dash lights were on but turning the ignition key had no effect except the radio light would flash... I decided to have it towed to the shop and while waiting for the tow, i put the key back in for the shop and it started dinging so (not doing that before) so i tried starting and it started right away. Does anybody have any idea of whats going on? have driven it and braked several times but it is doing fine for now. (this happened a couple weeks ago with my daughter too but it restarted and all was well till now.

 

Since the problem was intermittent , I never thought it may be a fuse because fuses dont blow and come back to life....so I suspected the ecm because it was replaced a couple years ago. Someone told me I should elemanate the starter, so I was going to go into the fuse box and jump the starter relay to see if starter was good.....but when I opened the fuse box I saw the problem immediately...just beyond where the battery cables attach to the fuse box is a jumper from neg to positive that is labeled 125v. It was totally burned up and a couple fuses close to it were melted. I thought the fuse box was damaged enough to replace it so I got another fuse box from pull-a-part and saw that replacing it WAS BUYOND MY PAY GRADE. , so I replaced the burned fuses and managed to repair the terminals and replaced the 125v jumper part and that solved the problem....I have no idea what happened to cause the problem . I would post pictures but I dont know how at the moment.
