My friend owns a 1996 Subaru Legacy Outback. I recently had to drive the car, but when I tried to start it it wouldn't start. When I removed the key a loud clicking sound came from somewhere behind the wheel. When I called my friend they told me that this happened all the time, I just had to unscrew and rescrew a screw on the battery (the green one in the top right of the attached picture). I did this and the car started.

I tried googleing this issue, but wasn't sure what to search for. Can anyone tell me what the problem might be, and if this is safe to drive?

    Most of the time when stuff like this happens, I blame either the battery, or the connections to/from the battery. 90% of the time, this pans out. – Pᴀᴜʟsᴛᴇʀ2 Mar 27 '18 at 17:36

That green terminal thing looks like a battery terminal designed to provide an easy disconnect : when parking at an airport for a 2 week holiday for example.

It needs either removing, cleaning thoroughly and re-fitting or removing and replacing with a quality new one.

  • Thanks! This used to be a car that was only used in the summer, so that makes sense. We removed it and now the car starts fine. It looks like the screw was pretty corroded. – Ian Mar 27 '18 at 18:39
