Re: Jumping off trucks

I use a 2003 silverado to jump other cars with just the normal cautions

Does it say something in the manual ?

Re: Jumping off trucks

Other than side post batteries are hard to put cables on, I haven't heard of not jumping. My 2004 Impala even has a remote Positive terminal to do just that, jump start it. Because the side terminals on the battery are very hard to reach.

Re: Jumping off trucks

Hooking up batteries in parallel (like jump starting) increases the capacity while the voltage remains the same. I don't see how a vehicle (or alterneator) would know the difference between 1 or 2 batteries connected in parallel.

A dodge mechanic told dad that about the dodge truck and the gmc last night would only click and tried to drain the other truck, was just wondering if all that was true and. if anybody else has had any experinces with this.

Nonsense! I worked at a car dealership and we jumped everything with jump packs. (Diesels took 2 jump packs). The remote jumper hook-ups are to keep consumers away from the battery and if you look at the electronics in place you will see the remote jump stud goes direct to the starter. It is supposed to be safer and keep the ecm from frying.

Re: Jumping off trucks

If its got a BAD battery it may not take a jump .

I find that with a GOOD set of cables most cars with a low battery will start almost instantly unless there compleatly drained

My daughter had and accident and i had to connect the cables dirrectly to the Alternator post to get it home as the battery cables were NLA :(

Stay away from that dealership, you wouldn't want that "mechanic" working on your vehicle. As for the GMC, there must be some other problem.

I've jumped other batt's with my '06' Lincoln Mark LT. Worked fine. Just the normal precautions, as mentioned.

I have both a 2000 Dodge Ram and a 2004 GMC Sierra and I have used both to jump other vehicles in the last month. I have no idea why the mechanic would tell you that they couldn't.

Re: Jumping off trucks

I though this was about jumping off a truck. Not jump starting one. :)

I know they make them pretty high but wow!@

Re: Jumping off trucks

Yea, Realgun, that was what I thought too - thought we had a SHT with trucks going on here. Oh well. :$

To reiterate - no problem jump starting a newer or older vehicle, but junk jumper cables make it very hard to do.
