Mainly lookin for Scott on this one <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />On my ZJ as some of you may know I've been experiencing some annoying electrical issues. First off my overhead display comes on and off as it chooses, and as of now will not come on at all. And the big problem I'm having is my head unit keeps shutting off when I'm braking. I figured bad ground, and Scott verified for me on my vehicle (93 Grand Cherokee) that the factory ground is no good so I made my own ground. Everything was going smooth for awhile then tonight I went to Walmart and whaddya know it shut off on me again like the little bastard it is. So now I'm mother f'n this and mother f'n that and just pissed off because I still hadn't put my dash back on from the last time because I just knew this would happen. So I continued on to Walmart and as I get there I pull out my phone and go straight to Google (like any good mechanic does <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> ) and then it clicked... It's not the ground causing all my issues, while it may not be helping either, but it's something else electrical related and I'm thinking alternator. As I brake I notice my in dash voltmeter drops down to ~11.2 if I had to make a rough estimate. The lights dim real bad too. Thats when it allll started making sense since it's been getting colder again the past few days.So when I left Walmart I tested that theory out, driving without the heat on halfway home. No real problems, it cut out for a split second here and there when braking but never completely shut off. Then since I had it all figured out I verified it but turning on the heat. And whaddya know the first time I hit the brakes for a stop sign it shut off!Long story short I figured out it's gotta be something like the alternator giving me issues. I'm not sure if it truly is the alternator because it's a fairly new looking alternator and the PO did say it had been replaced within the last year. But I'm not sure what else it could be. I went ahead and picked up some heavy duty (so the package claims haha) terminals while I was in Walmart and I'll start by replacing those because I know the posotive is cracked. Any leads on where to next would be greatly appreciated! I am considering the big 3 simply because 1: I do have a system in it and 2: I plan on adding more lights than are already on it. Sorry I type so much, I just like to be as informative as possible! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
