i'll give a description of what i did..........see if you can figure it out

 

1st, i've got a 2500hd '02 and i pull a 10,000 GW dump trailer behind it (landscaping)

 

so the trailer has onboard battery to operate the pump which dumps the trailer.......this battery has to receive power from the truck or else it would never get charged

 

well come find out it was spliced off the ground, giving no power and the battery never getting any charge..............makes sense

 

so i found the correct wire that has constant power (running lights)..........so great right, prob solved my battery won't die on me anymore

 

here's the catch: the battery on the trailer has power in it of course, i hook it up to the constant power wire (running lights) with the truck off, door closed, keys out of the ignition..........can someone tell me why the hell my door chime is going off?????...........

 

its receiving power from the trailer battery through the running light wire but what in the world does my door chime have to do with anything and why is it going off???????

YOu likely spliced into wrong circuit and the load that the extra battery presents is cause the chime to sound because it is cause a power imbalnce in that circuit and a different return path and when that happens some weird things can happen. I would suggest that you change you point of feed for aux battery in trailer.

It's not the "door" chime it's the "Hey, idiot you left your lights on" chime. Your truck should have a 12v accessory pin on the factory plug, this is what you should use to recharge the trailer battery. If I had the notion to go look it up I could tell you which pin it is...

Your battery on your trailer may be backfeeding to your truck therefore making your lights powered all the time even though your lights are off the chime may be powered thinking the lights are on.

Good observation! (That is why I suggested that he needs to change the point of feed for it)

the top left post on the truck (running light) is the one that has constant power.......the others are signals/brakes

 

i'm gonna go check again, look for a constant

 

thanks for the input.........gett'n there :)

i also bought the trailer used and the guy had a ford pull'n it so i don't know if there was a different config on a ford truck vs chevy

 

the way he had it wired for me is a ground meaning no power to the battery for charging

No wonder you are having issues. Take the time to run a feed line back for fuse block to feed trailer. Something around 12 gage will work for you.

okay soooooo, yeah i'm just gonna go with the constant i've got that makes my door chime

 

-BUT, throw a diode in there........prob solved with chime and i've got voltage go'n to my battery and i don't have to run a wire anywhere

 

always the simple things over looked haha.......thanks everybody!

The problem here is the limited current capacity on that circuit and hence the reason for a new feed. (I thought of a diode but it will add a little forward resistance and reduce charging rate some and not change/enhance circuit capacity either)

Okay here is your problem:

 

1) You are using the running light to power your battery when ever you have you trailer connected, it is back feeding the circuit causing the light on chine to ring (Like others have said)

 

2) Do not put a diode in there because

a) It is wired wrong so why cob it up even further

b) The parking light circuit is not rated (current wise) to be used a a charging circuit

 

3) Here is a link to the correct wring for a 7-pin trailer connector. This is a standard so it does not matter if you have a GM, for , Dodge, Toyota... it is all the same.... Wiring diagram PLEASE NOTE that the color scheme on this page is not always followed and you should use a test light to verify the connections.

 

4) If this is wired right check your engine compartment fuse block. There should be a large maxi-fuse in I believe the stud 2 position to charge the trailer battery (check your owners manual for the proper position). Do this before you go crazy looking/rewiring your truck... but correct your trailer side wiring ASAP before you over load your parking light circuit.

 

Hope this helps

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
