🔋 Battery issue…. Fixed…Maybe

[CamNak11]

Since this battery draining issue doesn’t seem to be just specific to the RHOs, but to the hurricane in general. I wonder if something like the electronic turbo cooler is staying on and just never turning off essentially draining the battery by the next day.

Wiring harness laying over under or near creating or inducing a voltage would make sense for something like high current stereo wires run down an injection harness screwing up pulse duration. I’m not willing to see it affecting a vehicle when it’s not running inducing a draw though. Right hand rule of inductance says if you picture a wire wrap your right hand around the wire with thumb pointing in the direction of current flow. The fingers will indicate the direction of a magnetic field it will induce. That magnetic field will induce a current in a secondary wire laying next to it. This might go to explain some of the intermittent rough running or catalyst damage on particular vehicles. Again, this might explain the situation if we had a very large current wire laying next to a very small current wire that was trying to carry a precise electrical signal, but not for a draw. As far as wiring harness, pulled too tight, causing connector pins to pull loose this would create an open circuit. Again an open circuit is not something that is going to cause a battery to go dead. For me, the battery dead issue would have to be caused by a short circuit or a hold on circuit keeping something on for a longer period than intended.
But hey I could be wrong, I’ve been wrong before just ask my wife.

so gotta ask now - since seems like its something we are all focused on .... test drove my ordered RHO today .... dealer passed PDI and had everything prepped .... we started it up in the dealer "bay" ... and idle went way high RPM's for a while ..... drove fine, seemed to get the "check back seat" alert a lot - but we did have 4 people in the rig ..... when the auto start/stop stopped the engine at red lights ... battery dropped to 12.2-12.8 (Red on the indicator) .... and then when auto-started, slowly climbed back to 13.2-13.9 .... seemed to work hard to get to 14.x . Looks like the batter indicator color is red at anything below 12.8 (I could be wrong) ..... should I be concerned ?

Should be fine, voltage will drop when the engine is off as the alternator isn't running

Thanks - im used to seeing a pretty solid 14.something ... but never had a dual battery setup (except on my diesel) ... the high RPM at startup, and it never really settled until I drove it, concerned me .... knowing others had battery issues. Bought from a local dealer so it went off the delivery truck last night and they did their PDI pretty fast for me. Red on the indicator makes me focus, but maybe thats normal ... going to check with my Durango (only other vehicle with auto start/stop)

All ram trucks have that high idle. My trx high idle when it started was so high if i was in a parking garage you could not have a conversation

When I auto start mine up, I notice that it idles high for what seems to be 45 second, then idles down. I don't pay as much attention to it when I start it from inside the vehicle, but it's really obvious when I'm outside of it using auto start. I've also heard others say this as well, so I think that aspect of it is normal for this engine setup.

“Red on the indicator”…hmmmm. Red isn’t good.

Did they replace your batteries during PDI?

Yes, my RHO engine idles high for a good 45 seconds after start-up. It may be normal on Ram, BUT when my BMW battery got low due to several weeks of ultra short trips, it would take forever to idle down after a cold start. It’s like the ECU was trying to “make-up” charge the batteries.

My current Ram has always done this in colder months. I just figured it’s trying to heat itself up.

Here is what mine looks like

Odd, as just looked at mine. Pink wires are routed on top of the harness. Yours is opposite.

Tech said harness had been “improperly” routed over the top of the pink wires. So, is proper routing pink on top?

Does it even matter?

Not sure I understand the color differences on the display … in this image battery is at 12.7 and red … at a different point I’m at a light with engine auto-stopped … 12.6 and no red
I’ll have to read up on it

If I remember correctly, I'm pretty sure his "red" battery level indicator is just a different display theme. He has red along the bottom of the instrument cluster too.

I'm not sure, it looked like he was specifically talking about one certain bunch of wires. Also looks like the fuse bok may have been moved out of the way.

Yours is at idle…his was shut down…note to tach.

I don’t think the red is a user selected “display theme”. I’ve noticed the display highlights change to accentuate warnings & such.
