My 67 Camaro is draining my battery every two days. I dont know what it could be. Its been re-wired, the alternator is new and it works great on a new battery, But after two days it wont even start.

 

hey, i have an 81 camaro and the same thing alwasy happened to me. What i did was buy 2 new battery terminals with little tumb levers, this allows you to lift off the negative terminal, if you then put the negitive terminal so its not touching any metal the battery won't die. I have been doing this for nearly two months with totall sucsess. other camaro owners i know have had the same problem and fixed it the same way. good luck

you need a test light, and a voltage meter. turn the car off hook up the voltage meter and see if it is pulling power, then find it by using the test light at the relays and fuses

 

I don't think I would settle for disconnecting the neg. every time you stop, there is obviously a drain on the system that needs to be fixed. I had the same problem with my 68. Try replacing your voltage regulator and see if that helps, that was what worked for me. Good luck.

 

i had a smiilar problem with my 69. if you don't find a drain in the electrical check out the voltage regulator. if your alternator is good put a volt meter on the battery terminals while some ong gets the RPM's up the volt meter should read about 14 volts. you can also take the regulator and have it tested. i bought mine for about $10 at autozone. so hprefully its a cheap and easy fix.

 

I just had the same problem about two weeks ago. you will definately need a test light to track down the problem. my problem was a bad wire between te alt and the regulator. I learned alot about my charging system from the experience if you have more specific information my e-mail is tommy_tompson@hotmail.com drop me a line maybe I can help

 

First make sure you have a good battery get it load tested its free at most parts stores. I had a similar problem on my 68 camaro. My problem turned out to be a bare wire under the dash touching ground. Sometimes it takes a while to figure it out just be patient. You can also start pulling fuses, if your battery doesnt die out you know its in that circuit.

 

Here is a long winded procedure which should identify the problem fairly quick.

If you are sure that the battery and alternator are OK, then you have two
possibilities.
One, for some reason the charge is not getting to the
battery; or two, the battery is being drained by a parasitic load or a short circuit.

You will need a digital multimeter with a volt and amp scale.

First find out if the charge is getting to the battery, there is a good
chance that the charge gets to the end of the cable and not to the
battery. For two main reasons, one being dirty terminals or the cable ends
are not as tight as they used to be. Also batteries with side terminals,
at times do not hold the cable connected tight enough, The screw may feel
tight but it has bottomed out before clamping down hard enough ( you can
fix this by grindingnthe end of the screw). Some of these batteries have
top terminals also, If so, start the engine and with the voltmeter measure
across the top terminals, you should be seeing at least 13.8 Volt. If you
don't see this, start hunting, check both the positive and negative
connections and the cable terminals also, on both ends. also check ground
straps for good connection.

If the voltage is good then look to see what is draining the battery,
1) Disconnect one of the battery cables. I prefer the positive, but it
really does not matter.
2) turn everything OFF on the car, including the ignition.
3)Set the multimeter on the amp scale. you may also have to plug the test
leads to amp jack on the meter. Connect the test leads between the
battery terminal and the cable you just disconncted.
4) The meter shoul show less 0.3 amp.
5) If the load is excessive you will have to disconnect one circuit at the
time to locate the source.
6) Go to the fuse box and pull one fuse at he time and watch the meter to
see if the load drops.
7) When you find the bad circuit you will have to trace it out, hopefully
you have a schematic, and find out what is going on. Could be a short, bad
component, or whatever connected to the circuit.
