It sounds to me like a dead battery. Depending on how accurate your voltmeter is, what you see as 12V may be 11.9V or lower. To give you an idea, an open circuit battery terminal voltage of 11.7V indicates a completely uncharged battery. What you are describing happened to me once with a Volvo car, due to a faulty switch in the glove-box; the glove-box ...

Sounds like the car charger has a short in it. If you really, really wanted to I supposed you could test for low resistance across the charger plug. Or, perhaps try plugging it into a different car and see if it blows the fuse there. If it was me, I'd try a different device in the car and verify that it's not a loose socket. If it fails that, I'd get the ...

I would just add a comment but I don't have enough points I guess. I just wanted to say you are addressing it correctly. The wrong thing to do (but tempting) is to just throw a bigger fuse in there. Avoid that temptation. It's possible that someone (previous owner maybe) has tapped into that circuit since it's an easily available 12V source. Trace the ...

According to this Fusible link FAQ: What size replacement fusible link should be used ? The automotive service industry recommends using the same gauge and length as the blown fusible link after the cause of failure is corrected. Ensure the size/length you put back in is the size/length you took out. Also, as I've highlighted, a new fusible link ...

Since the only thing that changed between the time it worked and the time it didn't work was the passenger door, I'd be willing to bet that's your problem. Since there is no way to diagnose the specific electrical malfunction with this site, I suggest removing all the connections from the passenger door, and verifying that everything works as it should (car ...

As far as the fuses are concerned, it's never a bad idea to add a fuse to a particular section of a circuit that you're concerned about. For the high-beam fuses, in particular, I would start conservatively. Your average high beam (for a normal headlight) is 55 or 65 watts. In a 12 V circuit, that's less than 6 amps nominally. If you put in a 10 amp fuse, you ...

Do you have a multimeter? Check the current across the fuse (should be zero with nothing plugged in), continuity from fuse-lighter and lighter-ground, and that there isn't any continuity across the lighter. If you can get to it, unplug the connector from the back of the lighter socket, that way you can check the socket itself separately from the wiring. ...

Also check the relay under the dash for the parking/running lights, I just fixed one in my shop 10 mins ago that needed the relay and new bulbs (bad bulb on one side caused all brake/run lights to go out if the running lights were on when applying the brakes) also check the sockets and contacts as well
