I just can't leave well enough alone. Wife says that all the time. Told me to stop messing with the XC60. But, I can't. Most of what I've done is pretty harmless. Even this. Got my 2015 XC60 back with a clean bill of health. All is well. Me being me I figured I'd hook up the battery tender pigtails with the loop ends. That way on Saturdays when we weren't playing I could hook it up, it'd be topped off and ready to go on Monday. However .... while tightening the (-) terminal just.that.much.more .... yep, I crossed with the (+) terminal. You could have welded with the sparks. Argh!!!!
I went ahead and connected the tender so it can do whatever it is it does. Just took a reading off the battery - 13v +/-. It's charged fine. But .... I have nothing in the car. No lights. No starter. Nothing. It's a dead vehicle. Checked a couple of random fuses and they were fine. Any hints as to where to start looking? Does it have a master circuit breaker? That'd be wonderful! (altho' I doubt it). Just need a good starting place to look. And then I promise no more tinker f'ing with the car.
