zmarrott Posted June 23, 2017 Share Posted June 23, 2017 So it first happened yesterday when i got to work. Ill commonly shut the engine off but leave the radio on for a few minutes, but this time i heard a pop in the speakers and all power in the vehicle was gone. Lights, horn, radio, dash, nothing had power. It started working again after a few min of me just visually checking the vattery and all my major engine bay fuses. Tried to drive it to work today and it started fine but i got maybe 20 ft and power started flickering with a click in the dash. Got it back parked and it did the same thing when i shut it off, all power gone. So i had to drive the brat to work (sarcastic 'oh no') but where in the dash can kill all electrical in the car? I can do electrical diag some but bad wires are a pain Link to comment Share on other sites More sharing options...
idosubaru Posted June 23, 2017 Share Posted June 23, 2017 (edited) Bad battery Poor battery terminal connection - clean posts and inside of terminals shiney clean. Bad battery cables Bad alternator Test voltage at battery posts and alternator output post, starter, and fuse box to see if you have a voltage drop across their supply cables or connections. A voltage drop indicates poor connectivity. Poor alternator voltage output shows alternator failure Edited June 23, 2017 by grossgary Link to comment Share on other sites More sharing options...
zmarrott Posted June 23, 2017 Author Share Posted June 23, 2017 Im at work currently so cant do anything at the moment but battety terminals are tight and havent been moved in about 5 months. In my mind, battery or alternator wouldnt cause such an audible click like a really loud relay in my dash when the power fails. Ill be doing diag on it tonight when its cool out but i just want to get as much info as i can before hand Link to comment Share on other sites More sharing options...

Subaru Scott Posted June 23, 2017 Share Posted June 23, 2017 The "click" you're hearing is the Ignition relay and/or any other relay for accessories you have on, losing power. Has nothing to do with the source of your problem. My guess is ignition switch. Link to comment Share on other sites More sharing options...
zmarrott Posted June 24, 2017 Author Share Posted June 24, 2017 Ok found it. I had tried wiggling the battery terminals but not the wires on the terminals. My positive terminal cracked causing the side that feeds the fuse box to be lose. Tightened it down and a chunk of the terminal fell off lol Link to comment Share on other sites More sharing options...
idosubaru Posted June 26, 2017 Share Posted June 26, 2017 (edited) Good find. Its often the connections at the battery. Very common. They can return later too - clean it up and it comes back a year later. Grrrrr Edited June 26, 2017 by grossgary Link to comment Share on other sites More sharing options...
