Still need help
 

I have a 65 mustang 289 motor and the oil light on the dash blinks on and off when i shut the car off and no turn signals and the alt and oil light blink like almost like hazard lights i replace the alt and regulator and the ignition switch now and don't know what to do next oh and i put a test light on the - battey post and on the disconect battey cable and the test light lite up thats not right is it any info please this is running me nuts

While you have an assistant hold the test light to the disconnected battery, start removing fuses one at a time until the test light dulls or goes out. Check and see which circuit that fuse is for, and post the results.

Make sure the doors are closed when doing this, or the interior lights will cause the test light to light up.

Take care,

ok i took the fuses out one by one and the test light did not go out then i tryed somethig else i disconnect the wire harness that conects to the voltage regulator so now what
