Being a Jeep owner I carry at least 0.5 of my tools with me at all times
My 98 XJ Sport has developed a curious habit of suffering total 12V failure when I do the not uncommon act of turning the key to start it... when this happens, all electricity just seems to be elsewhere in the planet, and not in my Jeep. Sometimes
I lose the constant 12V feed (and the radio presets go away), sometimes not. Sometimes I can jiggle the (-) cable, and it will start, sometimes the (+) cable... sometimes just removing and reinserting the 50 A batt fuse does the trick.
It NEVER just starts again without me jiggling something. There is mandatory jigglage in these situations.
This is not a starter problem, at least not internal, nor is it a BATT problem. Also related to this problem, when I am driving down the road, my voltage guage goes all the way past 19 volts
and I get Mr. CHECK GUAGES - but the Jeep still runs fine... if I turn off the Jeep in this condition (only happened once) then it absolutely will not start.
I have heard tell of ground problems with XJs, and I am figuring that the problem is likely related, but any suggs on what the hell
I can do to Dx and repair the problem would be nice. Kinda hard to was romantic with the little lady at dinner in a suit and a tie, only to have to throw on my gloves aand head under the hood to get home... though my sweetie thinks it's sexy (she's a Jeep girl, thank god~!)
