Thread: Battery or Alternator bad?

Tweet

I must ask. Were you guys foolin with me???? With my car off, some of you told me to keep my battery ground cable on battery. Unhook my positive cable from the post. Run one end of my 6 or 12 volt circuit test light to the battery + post then the other end of the circuit test light to the + battery cable. If the light lights up it meant I have a current draw from my car, draining my battery......And I need to find it by pulling fuses till it goes out. Well, the light lit up when I did this. Isn't this the same thing as having the cable hooked to the post thus of course it's getting power?

I tried this same test on my 63 Nova, my 2005 ram truck and my wifes 07 Pacifica. All 3 times the light lit up when I do the test.

My battery tested at 12.6 volts this morning and again tonight when I got home from work still outside the car NOT hooked up to anything. I put the car back together. Started the car up and running at idle of 1,000 or 2,000 rpm's I get 14.5 to 14.65 volts at the battery even when my electric fan kicks on. All sounds good. Right?

Went for a nice drive with fan running through a few cycles of on/off. Got home and turned car off to check the battery again and now it is higher voltage at 12.84. Great, right?

So tonight I am leaving it all hooked up and seeing what my voltage reading is in the morning after having set hooked up in the car for 12 hours.
