Hey Scotty! I have a 2001 Miata. I let it sit too long and came out to start it but it was completely dead. I charged the battery and hooked it up, there was some spark and then the headlights came on and stayed on. Key was not in the ingnition. I could only turn the lights off by unhooking the battery. I realized then that the main fuse was blown. I replaced the fuse and hooked up the battery and it blew again. Nothing in the car will work, no interior lights, not door buzz, no ignition, just headlights on by themselves when I hook the battery up and the main fuse blows everytime I hook up the battery. Any ideas?
Thank you!
Well it's got a gigantic dead short somewhere so get out some meters and start testing the wiring. Something is shorting out to ground entirely. You're going to have to test everything that runs off of that fuse from the fuse box on down to find what his shorted out, but it should be pretty obvious. Like maybe a rat bit through a wire and it's touching the frame or something
Bad ground! Found it Scotty! Thank you so much!
