Any ideas where to install a third battery in a '24 2500 L5P that's not in the cab? Doesn't have to be huge, capacity/size are totally negotiable (ideally at least 10Ah), use case is a UHF/VHF amateur radio transceiver.

Why do you want a third battery for your VHF / UHF rig?

 

My 2016 and 2020 Diesels never had a problem with an Icom 5100 or a Kenwood TH-710G hooked up to the passenger side battery.

 

  I just bought my 24 3500 L5P a few weeks ago and I’m waiting for a little cooler weather to install a VHF / UHF rig.

 

  If you’re worried about the rig drawing down your batteries when the truck is off I would get a West Mountain Radio ISOPwr+ and a 10-20ah lifepo4 battery.  I have this setup in a battery box so I can take it anywhere.

 

  I mount the radio under the back seat and the control head on the dash.  The 24 dash doesn’t have the tray in the middle of the dash so I’ll need to come up with something different.

My preference is to have a dedicated battery for comms to not worry about depleting the truck's system. An ISOPwr+ (or similar) is definitely in the cards. For mounting the Bulletpoint Mounting Solutions RubiGrid has really piqued my interest.

 

I'd love to pick up another Kenwood TM-D710GA, have one in the shack that I could repurpose but I really hope I can find another one at a reasonable price.

I see your point about the comms battery.  Here in AZ vehicle batteries usually last 2 years or so.  A far cry from WI where they lasted a lot longer.  On the other hand I've never had to replace an exhaust since moving here.

 

I need to stay off these forums.  

 

Now I'll be ordering that RubiGrid after I get home these afternoon.

 

Good Luck finding another Kenwood mobile.  I'm hoping they come out with a replacement but the new HT hasn't shown up anywhere yet either.

Hah! Please let me know how the RubiGid goes. I'm holding off on ordering until I decide what to do about the radio itself, we're coming into the PNW hamfest season so there's a decent chance of me finding a D710. HRO in Portland has one NIB for $1k in their special display case off to the side, nope!

The RubiGrid doesn't fit the AT4 / Denali stacked dash so back to the drawing board for me...

 

Good Luck finding a D710.

 

I found one a couple of years ago that a local had won in a hamfest and didn't want to invest the time to learn how to operate.  I wouldn't pay over MRSP for a radio that may be replaced soon.

 

I have a pretty good Kenwood collection, TS480 (200 W), TS890, D710 and the D74 HT.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.

      “It should be recognized, however, that there becomes a point where fuel economy oils do not make much economic sense for the end consumer—we talk about a fuel saving of ~€100 compared to a risk of €1000 Euros if the oil is too thin and causes increased engine wear rates. However, the benefit of these oils accrues to the car manufacturers. If their vehicles can save 1–2% fuel by using a special fuel economy lubricant, then that OEM can drastically reduce the amount of fines they need to pay.”   I liked this and the following paragraph as well but it’s really only touching the beginning of the benefits OEMs see from spec’ing these oils. After you factor in “out of warranty” service work and new car sales when these engines fail before their time, it’s a good racket for them. Just because you're paranoid doesn't mean they're not out to get you!
