new amp and new batt and everything goes crazy...please help me

after disconnecting the rear battery, there is no current and the car will not start...

I am going to check battery connections in the front. I am hoping that possibly I just did not reconnect the ground to the battery in the front properly

what do you mean?

Be very carefull not to screw anything up here. Your playing with fire, literally. Your wiring and batteries can handle hundreds of amps. You can electrecute yourself, fry your cars electrical system, set fire to your car, fry your new stereo system or have a battery exlplode in your face and blind you by spraying acid in your eyes.

Just be very aware of the dangers. Those batteries are always live, and the alternator wire is live when the car is on.

Be very carefull not let any bare positive wires touch the cars body/ground and be carefull to not allow any tools to touch both battery terminals (this is surprisingly easy to do).

It is best to do all your electrical wiring with the battery negatives disconnected and fuses removed, and only attach grounds and install fuses when your certain all your wiring is correct. Which in your case we know it's not.

Double and tripple check everything before you connect those negative terminals and fuses.

oh okay, I have all of the disconnected wires wrapped up with lots of electrical tape and I am taking precautions to be safe, I just did not understand what you meant

after I was away for awhile I cameback and noticed that my lights inside the car light up again. they did until I tried to start the car. it turned over once and then everything went dead again

bump, anyone ever have this problem before?

It sounds like you somehow drained your main battery dead. You'll need to charge it with a quick charger. If you don't have one, take it down to your local auto parts store. It will take several hours to charge. Sometimes they'll do it for free, or small cost.

You'll need to fix this before you can move on to fixing the rest of your system and figure out why you drained your main battery down.

I'd also have them test the battery to see if it is any good. Your alternator should have been charging it whenever you started your car. You may even have a bad alternator. Have them test both.

I messed around under the hood for a while and I cleaned the front battery's ground up and now the car starts. (although the original ground before cleaning worked fine with the old amp hooked up) the alt is not a problem it charges the front battery now that the ground was fixed I have to hook up the second battery to see if everything works. it looks like the car was running solely off of the rear batt. I am going to connect everything again and Ill get back to let you know if the problem is solved

the front batt rests at 12.3 now instead of 12.7...could it have been damaged?

I hooked everything up again now that the front batt is hooked up correctly. When the amplifier is connected to the rear batt is automatically shows power, but still gives no output (when everything is hooked up). as soon as the power wire was hooked up to the rear batt it caused the hu to turn on (w/o key turned on) even though the rear batt had not been grounded yet to anything other than the amp...wtf

up, anyone ever had a similar problem?

sounds like a bad ground to me.

yup, it sounds like ur front battery is not grounded out i would check all your grounds and make sure no paint is inbetween the metals

 

[allout13 10+ year member]

checked the front batt ground and it was bad, but I fixed it and now the front batt works fine, but I still have other problems. ^^^^
