Losing voltage when the brake is depressed, headlights and

Customer Question

Losing voltage when the brake is depressed, headlights and turn sign is on. Previously I hit the horn which ended up getting stuck which eventually blew a fuse. The alternator was checked last year but not sure what the problem is. Also losing voltage when turning on the radio.
JA: Working headlights are essential for a safe drive. Luckily, the mechanic I'm going to connect you with will have just the tips you need for a quick fix. Are you hoping to fix this yourself?
Customer: Yes, if I can
JA: Great! What have you tried so far?
Customer: Check the fuses, as I've stated the alternator was checked last year and it was good.
JA: Is there anything else the Pontiac Mechanic should be aware of about your Pontiac?
Customer: There's a rattle that's loud only when driven around 5 mph.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Pontiac Mechanic about your situation and then connect you two.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Lets start with taking a volt meter and at the battery with the engine running check and see if you have charging voltage at the battery , the normal charge rate with the engine running should be right at 14 volts. Check this for me and post back with the results and we can work from there.

I realized that there are 3 wires that appear to be the headlight wires they looked chewed up and I'm betting that's what's causing the voltage issues.

I sent some pictures, not sure if they were received?

Battery and regulator appear to be okay, if it's not those wires ( which I'm almost positive that's part of the problem) could it be the voltage regulator?
Expert:  Ron replied 1 year ago.
If the regulator is failing the voltage will be low, what is the voltage at the batter with the engine running?
