Jump Starting- any precautions?

I don't know how sensitive the electronics are in these trucks (I have a 2003 GMC) and am wondering if there are any precautions when jumping someone else or particularly if you are the one with the dead battery. Just had someone ask for a jump today.
 
+ is for positive red goes here and - is for negative that’s the black on your jumper cables. If you line those up it will work.

all joking aside I was concerned too about using jumper cables with the electronics on these trucks, but as long as you follow the owners manual you’ll be fine. I’ve jumped my farm tractor a couple times now with no issue.
 
I know, I know! I couldn't have resisted such a stupid question either! How do I delete it before I get too much s***. I'm new at this!
Not new to being stupid, just new to forums.

It’s an honest question so don’t feel bad. As expensive as these trucks are it’s better to ask and be sure than to fry your truck.
 
A friend of mine used his ecodiesel to jump start someone, and it blew the fuse to the electric steering

Just buy a jump pack, and keep it in the truck. They are pretty cheap, and work great.

And I thought I was the smart one getting ready to suggest this! A couple of weeks ago, we were out off-roading in the middle of nowhere and found a couple that was camping and had killed their battery by playing the radio the night before. I cleaned off the terminals and gave him a jump. The terrible condition of his battery gave me pause to what his vehicle would draw across his crappy, thin cables. The next day, I ordered a jump pack.

They are fantastic. And hold their own charge very, very well. I had to use mine this winter, and hadn't charged it for well over a year. Possibly into the years territory. And it's left in the car year round.

Worked 100%, with no problem at all.
 
I use jump pack. Used it SO many times. On my truck only once so far. But it did help a lot of people I don't know.

No question is a stupid question.

The jump packs work great. Noco GB70 easily started a Cummins and a Powerstroke even without a fresh charge. I try to charge mine every 3 months or so. We have one in every vehicle.

That is great to know, especially since the Noco GB70 is the one I purchased! :D
 
It's been stated on another thread somewhere here but the NOCO is worth every penny. I have one in my truck, wifes 4Runner, and the Yamaha SXS. I also carry jumper cables but the NOCO is my 1st tool when something needs a jumpstart. The cables are a last resort now.
 
I have NOCO also. Started my truck , zero turn , ATV and someone's else cars with it no problem. One time guy delivered few pallets to our workplace and his truck would not start (box truck) so I went to my truck and brought NOCO and he smiled at me like "are you kidding me". Truck started at first turn of the key. After that my boss bought one for the company use.
 
Wanted to bump this thread again, as the GB70 is currently $180 on Amazon. Ok discount IMO.

I have a GB40 for my 4Runner, which I anonymously recommended in my first post on this thread, and like all the other posts here it's fantastic.

I was gifted a GB50 for my birthday, for my soon to possess truck, but I've since swapped it for the GB70 - and figured the place may enjoy the good price.

For DC. So your truck since it's 12v Connect hot (+) first. Then negative (-). I know it's bassackwards from residential. But it's the way it works.
 
Resurrecting this thread:

I gave a guy a jump yesterday with my passenger side battery. ( Cummings SO) I know on my diesel Land Cruiser, I should only jump (either get a jump or give a jump) from the passenger side battery because the truck is 12V but the starter is 24V. If I jump from the driver side it exposes the battery combiner to the jump which could possible lead to a failure. Do you know if the 6.7 Cummins has a similar setup? Any particular precautions I should consider when jumping?

No the ram is a 12v system only

I don't want to derail this thread too far... but do you know how the truck uses the driver vs passenger battery? Are they tied together in parallel as one big reservoir? Or does the truck use one as a "house" or "Accessory" battery while it uses the other as a starting battery? (I'm just wondering if I could jump start myself, if the truck uses only one as a starting battery)

If this is covered somewhere else, feel free to tell me to go search or similar.
