    I rebuilt my 2.5 in a 93 jeep yj. Put it in started to wire it up and now i have a 12v constant to block. Every electrical component in engine has been bought new and changed. Just can't find the wire or wires doing this. Any ideas.

    When you put a test light to negative battery terminal and touch anywere on jeep. Block or frame. The light comes on on the test light.

    Are you hooked up to your battery correctly. Red cable to the + sign side and Black cable to the - sign side. If so it sounds like you have a bare 12v+ wire touching both the block and the frame.

    im convinced that most electrical trouble is created by work done wrong or messy wiring, NOT factory failures. components go bad, wires just sit there!

    There is a lot of variables in this situation. I checked my shop manual and you should have a body grd and engine grd. Only you know what you fixed spliced or repaired so maybe look at what you may have done in repairs first. Also if you go to the power distribution center and start at one end and pull fuses to you get rid of your voltage reading then pursue that circuit to find the culprit. I listed some pics for you to look at. Let me know if you need any other help.
