Ok so about 2 weeks ago I was driving panzer...and it died, I pulled to the side and set it in park and i went to started it and nothing...only the P light on the dash board would light on but when i switch the key further to start it...everything would die...so I assumed at that momment that my battery was dead...anyways called my wife since i was not far from the house and I got a jump start...the truck started and we drove home.
Once home i let the truck idle for 1 hr or so...i figured this would give the battery some charge since I have drained my old oem battery before by having the stereo on while washing and detailing the truck, and all it took was a jump start and let the truck idle for 30 min or so then the battery would go back to normal. Anyways so after the 1hr of idling I shut off panzer and go ahead and try to start it again and nothing not even a click from the starter. At that moment I decided to call odessey to start a claim since the battery is still under warranty. Odessey boys have me drop off the battery to one of their authorized distributors for testing...monday morning they call me back that they charged the battery and tested and that it is all good to go nothing wrong with the battery other than it was low. So I pick it up bring it home and hook it back up in panzer, I go to start the truck and no scheiße it indeed starts, so I go for a test drive and everything seems normal when again the trucks dies...but this time the stereo died first and 3/5 seconds later panzer dies. Again i have my wife come jump me...and panzer starts back up...come back home and go to shut off the truck and it completely dies again...the key is stuck in the ignition, so I popped the hood and unhook the black terminal and hook it back on this bring the power back to panzer and I'm able to get the key out. I then proceed to lock Panzer and it locks, I go to unlock it and it unlocks, I push the panic button and it starts panicking, I push the panic button again and it stops, so then I proceed to try and start Panzer again and nothing it dies and the key is stuck again in the ignition. At this moment I'm thinking the battery is fvcked up and the guys at odessey messed up. But i decide to go thru the same process of unhooking the black terminal and hooking it back on to retrieve the key. I retrieve the key and lock Panzer once again. then I proceed to do one more test...and take the battery out of panzer and decide to hook my portable air conpressor. And well the damn compressor start pumping air normally for about 3 min after that i decide that it is not the battery the one who's messed up but rather something with panzer. So I leave it. Today after work I say screw it let's try and start Panzer once again so I grab the battery hook it back on and go to start Panzer and it starts right back on once again...then I go to shut it off and it just dies again...key stuck in the ignition again...so I unhook the black terminal again and hook it back on and I'm able to retrieve the key and lock the truck again...so now I don't know what the hell it could be, terminals arer aftermarket ones, and everything is tight and snugged with the terminals and cables. My next options i think it is maybe the passlock got disconfiguired or messed up somehow. Another option that comes to mind maybe it could be the ignition thingy that is messed up. As well idk if thats something i can replace or the dealer has to work on it. My last option is to guess maybe a relay or fuse is burned out or something.

What do you guys think ???, I'm going crazy here...i hate electrical nonsense, could a messed up alternator cause these sorts of problems???, I just don't wanna have to fork out a lot of cash at the moment, which is why I'm trying to have the dealer to be the last of my options here.

Passlock could be a factor. Is the security light showing up on the dash? If so, the H3 will likely start after a 10 minute wait period.

If it''s not a Passlock issue, the first culprits are battery terminals, cables and grounds. You can rot out a cable from the inside from a leaky battery. Bad grounds, just about anywhere, could create issues. I know you've done a lot of work on Panzer and I would go over the wiring carefully. New connections should be soldered and not using a Scotchlok. Look for loose connections - it's better to tug on wires and expose a weakness than be gentle.

Going back to Passlock - I had issues for weeks, bought a new ignition housing but never installed it and it's only failed once in two years. Weird stuff.

You got air and fuel... Otherwise​ H3 wouldn't run.
Ignition????
That is the question!

Battery
Cables both and connectors cleaned and tested for continuity
Main grounds removed and cleaned
Positive battery wire to starter removed and cleaned and continuity tested
Connectors under fuse box
Connectors at ecm / pcm
Main fusible link

Other items:
BCM has gotten wet from drains for sunroof
A aftermarket stereo wire is shorted
Regulator in main brain damaged
Theft pass lock system active
Battery replaced with another for testing purposes

Just some stuff

The light comes on but it goes away I read some about it and I'm not completely ruling it out, however I haven't done the 10 min wait I'll do it this evening if I get the truck to start and then try it then if it dies when shutting it off.

As well the only additional cables I have ran is for the additional back up light I did soldered all cables and connections use a relay and fuse. I should have mentioned that my first issue happened after I replaced my passenger side tail light blinker...one of the two wire looking thing in the bulbs was broken so that was causing my blinker not to work...anyways I got the same light bulbs and replaced them all 4. And when to the grocery store...probably spend 40 min in the store and when I went to start panzer, nothin g it was dead...so I got a jump start then and drove home. And that's when all my problems have with starting basically started.

Welding with the battery hooked up?
I did that unfortunately for almost all built 'till my friend the welder who came to inspect my welds told me that I should have unkoomed the battery...so maybe my pcm or something got F-ed up.

Going to clean and check all connections and even thinking on replacing relays and fuzes since that a relatively cheap thing to do.
I did installed an after market stero...in going to unhook it and see if that solves anything might even installed my old tail light bulbs and see if that might have anything to do, I'm gonna try everything and anything at this point, next will be to check the pcm and bcm lastly is gonna be the key fob thing

I've never personally had any damage issues with welding while powered up. Still...I do heed that advice because it is so expensive to repair vs one minute with a 10mm wrench.

I did do some welding on a buddy's camper trailer, and the tail lights of he truck flashed while welding. So I unplugged the trailer from the truck and finished the mod. It was 2013 Durango, and suffered no damage. It was weird and I was concerned that I maybe fried something...but all was good.

So ever since that day...I take the battery cables off (both of em).

Yeah I wish I knew that then...probably why that blinker light burn out...hoping is not more than a burned out relay or fuse or even anything pass the key fob thing that messed up or the passlock.
But my buddy told me, he saw a semi getting messed up and not starting after it had some welding done to it with the batteries hooked...turn out to be its computer got messed up.

Sorry to hear all of this ..... I know it can be very frustrating. I have seen the ground to engine block literally split, rot or melt off when electric issues arise. I've first hand see a battery have a oh $hit moment and it is something else.

Ok so i went and drop off the battery since I couldn't get panzer to start, and my portable compressor would run on and off so my guess the battery is messed up...hopefully this fixes my problem and if not then at least I'll have a brand new battery and I can rule out that, then it would be to check the alternator.

Update to my issue...i got a brand new battery today thanks to odessy' s warranty, I plug it back up and it started right up...shut it off and it started right up again, so I then went ahead and drove for 6 miles and have no issues so far...last test ride after I got my old battery back I wasn't able to drive more than 2 miles when panzer died...im gonna adventure further tomorrow and the coming days...but so far it seems it is fix.

I plan on installing a rubber pad under the battery deck so it helps assorted some of the vibration from the car. Idk but maybe all the pod holes and bumps on the road and theirs vibrations, could have messed up my old battery.
