Can't wait for the next video, Dallas Auto Diag 👍 SHARP, Dallas Auto Diag From Nick Ayivor from London England UK 🇬🇧 ⏰️ 13:04 Good Afternoon

Thanks Nick!

I don't believe it's the fuse box , in order for the fuse box to be shorted the fusebox needs a ground to draw current . When you unplugged all connectors except the batt + it lost a source of ground . . . Thanks for posting your process brother keep it up . I'm on to part 2 !

Thanks Gilberto

[@russellhltn1396]

4:55 - the current draw switched from negative to positive. Meaning the battery is now being charged. I think part of the problem is how you connected the battery maintainer.

[@DallasAutoDiag]

Honestly I never noticed that. Good catch. 👌

I'm waiting for next video. Thank you for shared useful videos 🌹🙏

Mid video comment: Wow super fascinating. My first thought was a thermistor(ntc )that is heating up and resistance decreasing creating a steadily increasing short. luckily something like that makes it easier to find. Modules waking up will be more stepped amp increase. Interestingly enough as I just found out ntc thermistors are made from a semiconductor like what you might find on a circuit board. So looks like a semiconductor on that board has gone rogue. OR two conductors that are barely touching and as it heats up and expands they connect more 😅🧐

[@DallasAutoDiag]

It's definitely a possibility. Maybe who knows. Stay tuned for part 2

[@philh9238]

My first thought was the alternator causing the drain.

[@DallasAutoDiag]

That's a possibility for sure

[@danman9017]

i would check if the altenator is hot did not see you check that

[@DallasAutoDiag]

That's a possibility for sure.

[@carld1966]

Where's the other power coming to the fuse box?

[@DallasAutoDiag]

From the smaller battery

Please what software are you using for the wiring diagram

@@DallasAutoDiag how can I get it from you

[@carld1966]

The power control relay has power coming in from the battery then to the fuse box. Your meter is bypassing the relay. Shouldn't the relay stop power going to the fuse box.

[@DallasAutoDiag]

i think the relay is normally closed.

Part 2 with full diag???

[@DallasAutoDiag]

coming in a couple of hours

[@NextLevelAutoDiagnostics]

Did you test the batteries 1st?

[@DallasAutoDiag]

What kind of test do you mean?

[@prashanshan7125]

Keep it up..!

[@DallasAutoDiag]

Thank you, I will

[@karmicmessenger]

alternator or starter...

[@DallasAutoDiag]

Possible

[@chuckvoss9344]

Get your IR Camera out ...

[@DallasAutoDiag]

I thought I did in the video. Maybe in part 2

[@chuckvoss9344]

@@DallasAutoDiag I am thinking another pass with the IR Camera. Whatever is consuming all that power has to be getting warm/hot. When is part 2 going to be posted. Inquiring minds would like to know. This is crazy interesting.
