I noticed on the truck Im looking at has 2 batterys, Why is that? Thanks

 

Is it a deisel?

 

If it's a diesel - that's the way they come from the factory. If it's a gasser, someone added one for some reason - like a winch, off road lights, maybe even for a big stereo system, or just 'cause they had money to burn!

 

(Assuming it's a diesel) It takes a lot of power to turn over a diesel and at the same time operate the glow plug system... 2 batteries.

 

Yes its a diesel. Thanks for the help guys

hahaha I just realized this also. Out of habit I just looked at the left side for the battery and did not notice the one on the right. Just the week prior I was working on the electrical system and only disconnected one battery. Good thing I did not get shocked. ****ing in my pants from gettign shocked would have ruined the leather seats.

 

Uhh - can you GET shocked with 12v dc?? I always unhooked to prevent shorts while working.

 

Can you get shecked, by 12 volts? YES there is enough amperage in a car battery to do more then shock you if the power travels the proper path and you are working on the battery or on a non-fused wire.

 

Absolutely! There is enough amps there to do serious injury if the right contact and conditions occur.

 

Everytime you double voltage, you decrease amperage by .5, so assumeing oyu have 2*850 AMP batteries that's 12 volts, 1750 amps. That would convert to 192 volts 110 amps. Nothing to play around with.....

 

Huh - well once again I learn something new - I thought it had to be AC to shock. O well - I've always unhooked the batterys anyhow and will continue to do so!!

 

yep, i had a friend working on a generatory that used a 12v battery. His arm touched the battery while he was tightening a connection and he ****ed he pants from the shock. After we checked he was OK be proceeded to bust his ***** about it for the next couple months as all good friends should (he will not do that again).

 

DC kills too. Lick your fingers and put them across one of the old 72V lantern batteries, see how long you can keep it there. Keep in mind its not the voltage but the current that causes the damage, only takes like 100mA to interrupt your heart.

 

1BAD350 is right it only takes a few milliamps to kill. There's more than enough current in the glow plug relay system and batteries to do serious damage. I was working on the distributor of my old Mustang about two years ago. I left the key on (wasn't thinking), removed the cap, and then proceeded to lift the energized distributor out with wet hands -- WOW
