In my 1989 F-150 the battery light indicator comes on whenever I rev-up the engine, and the battery gauge pegs out and then when I push in the clutch the gauge goes back down and the light turns off. I have replaced both the battery and the cables not long ago, and am confused on what is wrong any help would be appriciated.

Try checking the alternator output.I think you have an internal voltage regulator, and it isnn't up to the job.
