I have a 84 mustang with a stroker motor. Over the last week I noticed my radio would blackout when I either slowly rev or rapidly. It will come on within 15 seconds, but will blackout each time I accelerate. Don't matter if in gear or parked.
My battery has 12.6v prior to starting and 16.5v at idle. No idea what volts it produces revving. My Tahoe produces 14.8 at idle, so huge difference.
This a trunk battery relocate with 2ga wires. Brand new battery, last one didn't wether so well FYI. I do have a toggle lever to kill power.

I'm perusing my Chilton for ideas. Someone suggested a radio ground, but I'm thinking alternator regulator, not sure how one would test this? Any input would be most appreciative.
Thanks in advance.
