got new battery but still no power

maybe a bad solenoid in the starter motor, if you get no click, if they still make starters the way they did several of my cars ago.

oh, no lights. bad connection somewhere.

main fuse.

(what kinda car are we fixing?)

contact on the battery terminals is possibly poor. tap them with a hammer Loosen the lead connectors a little and twist the connector leads around the battery post a little. re tighten.

Alternatives.
1. The new battery you bought may need to be charged.
2. you have the leads connected to the wrong posts on the battery.
red = positive
black = negetive (usually the other end of this lead is bolted to the chassi or body of the car).

one of these days, you go tapping battery posts with a hammer, you're gonna have one break off on you.

leave the hammer in the toolbox, sluggo...

cleaning and tightening all the contacts is always a good first step.

and connecting them backwards usually gives you a funny sign right away...

Hey, that's what I thought, too!

And as I know absolutely nothing about the inner workings of cars, I'm mightily impressed with myself!

I said TAP not beat the crap out of it.

see, you can't even spell it without capitalizing it.

no hammers aloud.

why don't you watch quietly with msO while we fix this car for the nice gentleman?

auzzies...

And you cant tell the diff between a lady type person and a nice gentleman

or a kangaroo?

a hammer only gets you so far, jocko...

After checking that the contacts are tight and place in the right way, I would give it another jump to see if someone had sold you a discharge battery.

If it is a deeply discharge/non-charge battery new or not I would return it as a lead/acid cars batteries do not like to be deeply discharge and it life will likely be shorter then otherwise due to that condition.

Jesus. Get a frakkin' room.
