Battery charging location on diesel

gnty · 03-26-2016, 05:37 PM

I've googled it and done some searching but still can't find where I put the negative to charge the battery's located on the frame rail. The positive has the stud, some readings say there is a negative stud but can't find one. When jumping it I go positive stud and negative to frame or spring bolt and that works, but not for charging. Any direction would be great. Thanks

There is no negative stud. I usually use something handy back by the rear spring on the frame... can't say exactly what, it depends on what is cleanish and part of the frame for sure.

Mine is the same as Jage's. I did add a negative jump stud that I got from Summit:

Just gives me a clean connection spot if I'm covered with mud and need a jump.
Are you opposed to adding a connection point so you don't have to crawl under the vehicle to charge the starting battery? Most chargers don't require heavy bus wire just to charge.

Thanks Jage and Dave for the input. Frame and undercarriage is quite clean, i've thrown the negative on a few areas there on the rear spring and frame but the charger still doesn't recognize a proper connection. The last thing i want to do is drop those two batteries off the frame and charge directly to each battery but its looking more and more like i'll need to. Those things are such pains to drop.

There could be something else wrong, if it's a good ground. ..apply the negative clamp from the charger and either take a voltage reading from clamp to stud or a resistance reading from clamp to another ground point. Basically you're testing if you're making good ground contact at the clamp. ..it won't save you from dropping the batteries because something else is probably wrong but at least you'll have an idea that dropping the batteries will probably just be a precursor to replacement.

What is the status of the batteries? Will the vehicle start?

Back a few weeks ago the vehicle would fire. For the last week or so when i've needed to move it there has been nothing and had to jump it using a booster and a truck hooked to it. This morning i ran out there and tried hooking the negative to many different locations and the charger still wouldn't recognize any of them. Your right Jage, there might be something else going on. I'd better drop them.......i'm cringing.

Sounds like the connection to the batteries is bad. A simple (once you drop the batteries that is) clean up may be all thats needed

Yeah I agree with AT, I'd be looking closely at the connections especially the battery ground and then make sure the battery or batteries are up to par. Also some of these new chargers are tricky to get a battery to accept a charge if it's discharged too far.

Thanks you guys for the time you took to respond and give advice and recommendations. I think your right that there must be something with the connection or they are completely toast. I'll get them pulled and see what I can find. Thanks again
