Question No electricity

Good evening fellow Camaro lovers, ha..
Was driving car today, for no apparent reason, all electrical power stopped, car stop running, radio quit and just glided on its own power into parking lot, won't take a boost off vehicle or battery pack, no lights, ignition, radio, etc, Any ideas? fuses? Battery completely dead?
Thanks ..

Re: No electricity

My first thought is the battery. Check it first. After that is ruled out, check the power junction box on the radiator support.

Re: No electricity

Check the bulkhead fitting in the engine compartment opposite the fuse block. If the bolt is not in and it pops off you are dead in the water.

Re: No electricity

Sounds like a blown fusible link at the battery. Check the wire for blistered or burnt insulation. If so replace that piece of fusible link.

If you added any electrical loads (radiator fan, electric fuel pump, a Giga Watt stereo amp, or even a death ray for when you get frustrated in traffic) to the car you may have to increase the amperage on the fuse and the size of your car's wiring to handle the extra power.

Re: No electricity

Had that happen at near midnight coming home from the track at night on a dark road with no streetlights

Found it to be the battery ground at the motor was loose.

Re: No electricity

Junction terminal on the radiator support. all power to the car comes from the batt to the terminal and then to the buss bar on the horn relay.

Re: No electricity

Brothers from a different Mother,
Checked all your suggestions, all seemed ok ..put in a different battery and the car fired up immediately ..
I did note when removing the battery the negative terminal connector was a wee loose, could that have been the reason for the battery being dead? It is only a year old. Is there anyway to make sure the alternator is working properly..
Thanks again.

Re: No electricity

When cars are slow to start or need jump starts, my flawed, but semi-reliable test for alternators and batteries is this; at night, with the car running, turn the headlights on and rev the engine. If the lights noticeably brighten and fade with the revs, then I look at the alternator. If there's no real difference to the brightness of the lights, then I look at the battery.

Doing a search on here, I found: https://www.camaros.net/forums/19-ele...d-battery.html

That seems strange to me. after the car is started, the car is powered via alternator. So, if you were chugging along, the loose cable would not have been a factor.

please correct me if I'm wrong

I remember that as being kind of a test but the other way around. Reving car up alternator puts out almost 15v and at idle at battery 12v, alternator/regulator is good. If no change your on battery voltage, alternator/regulator problems.

Get a voltmeter and measure at battery terminals and see if voltage increases to just under 15 when reved up. Poking around with a voltmeter to check things will tell where your issue is if it wasn't the battery.

I had an issue with my car that drained new battery overnight, got running the next day with a a jump, same thing day after. Turns out it was a bad external regulator drawing 1.2 amps with nothing turned on in car.

I believe that was true at one time but I'm not sure with all the computerization in cars today. I know that my 69 will run with the battery disconnected but have never tried it on my newer car. You didn't specifically say what car that you were driving. You just said "my car".

Probationer.....Sad that you had to waste money on a new battery and it looks like it was just a loose/dirty terminal. The battery terminals are the FIRST place to look when you have no power and if it was your Camaro, it is strange that it just shut off. A bad cable would keep it from starting but shouldn't cause it to just shut off.

Agree with Fried Okra
First place to check is cable clamps to post interface.
Battery post tool is used a lot
