I previously posted in the Vic forums but got no where so i thought i would (should of originally) post it in here.

Guys ,

I had a situation where i left a door ajar overnight and well you guessed it my battery was dead. My question to everyone (and i know its dumb) is actually 2 fold.

Where do you go to both jump start & charge your battery for your car.

Its either at the battery &/or at the fuse box.....

The reason i asked was that i tried to charge the battery in situ via the fuse box under the bonnet but the meter on the charger went ape and peaked at 8 amps then reset back to 0 and then again to 8 amps. Which actually scared the crap outa me as i couldnt get the connectors off fast enough... BUT when i connect it to the battery it goes to 2-3 amps as per all my old NA cars of old...

I did jump start it as the car was in the garage head first so i opened up the boot and did it that way. I am sure you can do the same from where the fuse box is as well but actually can you CHARGE from the fuse box area is really my question as I should of stated firstly...

Now this question on behalf of all the dumbasses out there that were too scared to ask (me included)

yes you can charge from there. when jump starting and charging you should put the negative to part of the engine to give the starter a better chance and because it usually well connected to the battery. sounds like the terminals of the charger were shorting out or trying to run something else whilst charging. i cant imagine what else. try it again and check before switching it on connections are good and cant short out

charge at the battery. jump start at the battery too. in the past i've tried jump starting at the fuse box and it would barely turn over. moved around to jump start at the battery and started fine.

also when charging you should have the battery disconnected from the car, otherwise you can risk blowing stuff if there is a surge.

Cheers guys.

yes i know to use the engine or component for the -ve and disconnect the battery while chargeing I just thought it odd that the charger peaked at 8 amps at the fuse box yet straight after (2 mins) when connected to the battery it draws 2-3 amps.

I suspect this is due to the battery location in the boot . I mean the battery would have to have cables going thru to the motor hence it may put a load when charging from the fuse box?

who knows.....

positive to positive

Negative to ground on car somewhere

safest way to jump start

for charging just plug into battery, +ive to +ive... -ive to -ive

Thats strange. I always jump from the fuse box and it turns over without effort.
