I just got home from the cottage and my old 92 Eagle Summit has a dead
battery as one of the kids left the door slightly open when we left for
vacation. I went to boost it using our 2000 Montana minivan. On the Montana
see clearly marked a remote positive jump starting terminal but I see
nowhere to connect to the negative terminal of this charged battery...the
battery seems very inaccessible...unlike the battery posts on older cars. If
I want to use the charged Montana battery to boost my old Summit where do I
connect the negative cable on the good battery of the Montana?
Thanks for your advice.
Any good metal contact on the engine will do. That has always been true.
You never were supposed to use the battery terminal when jumpering the
My sierra has a big flat plate next to the remote positive terminal.
Yeah, I was thinking of the discharged one. Anyway, it really doesn't make
any difference. The engine is a good connection to the good battery
negative too. And probably better than trying to make connection to the
standard side mount battery cable where all you can get is a little bite of
I remember one time we could not get around to the front of the car so I
just pulled up and got the metal bumpers to touch (metal bumbers - that was
a long long time ago). Then doubled the jumper cables to reach to the front
of the car and used the frame and bumpers as a return. That worked too.
Used to be you could jump a car with only one cable, by having the cars'
bumpers touch. However, with the modern plastic bumper covers, those
days are gone.
However, strictly speaking, you really do not have to have either
cable connected to the battery on either car. As long as you can find
someplace on each car that gives a solid connection to power and
high current. That is why a battery works best. For example, if you
were jumping 2 Fords, you could connect the postive cable to the
hot side of the solenoids, and the negative cable to the engine.
Hell, on that kind of set up, you could touch the positive cable
to the starter side of the solenoid on the car with a dead battery.

Just a tiny caution here, if I may?
Seeing as people around the world read and enjoy
these groups, it might be worth pointing out that
NOT all cars are (or were) negative ground.
I'm sure that at least at one time English cars
used positive ground systems.
