Recently repaired from a front end collision the battery tray was damaged preventing me from securing the battery. Decided to relocate to the trunk (the problemsbegin) the car acted like it was over heating which turned out to be a ground problem. Fixed that. Then rather than running two lines from engine compartment to the truck I grounded it to the back seat bolt (where the seatbelt is secured) I tested the power and everything checked out however when I tried to start the car the lights on the dashboard flashed and there was a crazy beeping noise from behind the radio. The car will turn over once then nothing but the strange beeping from behind the stereo. I moved the battery back for giggles and I get the same results. Does anyone have any ideas? I'm all out. One other thing is if you try and turn on the lights they don't come on but all the lights on the dashboard do..... It's driving me batty!

 

that's hard to say.
but, it is always said to start with the basics.
perhaps your battery is going out.
need test with a worthwhile tester - like the 200 to300 dollars tester at parts stores (autozone for one)

 

Thanks for the reply but it's a new battery.

 

what size wire did you use for the battery cables? you need a large diameter wire bigger than 4 guage. but i would make a dedicated ground point to the chassis and you must scrape the paint off for a good connection.

 

I used 6 Gauage for the power and 2 for the ground. I tested power from the back to the front and it measured fine. The problem is now if you try and turn on the lights without even trying to start it the blinker, highbeams and all the check lights light up but the headlight never come on. I think somthing is toast just not sure where to start to look.

 

Could it be the multi-function swicth? How can you tell if you burn that out?

 

is the ground from the body to the block ok ??

 

Thanks to all who replied I found the issue by accident the poistive side to one of the headlights had rubbed against the body causing a slight cut in the inslutation which created a fault to the body. Very Weird! Thanks again.

 

If you still plan on relocating the battery to the trunk, you really should be using some thing along the lines of 2 or 1 gauge, DC drops very quickly over long runs and will over heat a wire that is too thin for the run. Here is a simple voltage drop calculator, you should aim to get the same drop as the factory wire would have. I would figure your load around 100amps for starting purposes. http://www.powerstream.com/Wire_Size.htm

 

the flashing lights and beeping sounds like an alarm. mine does that to.
