thanks guys, so this is the ground in the fuse block?, and how I can test if the ground is ok?, thanks

 

I missed the huge black arrow in the pic, too. Yes, that is the connector I meant; the wires to it are a bit tight inspect them for fraying etc.

No not a ground. There is no "ground in fuse box".

My experience has been that when filling and burping the cooling system some liquid always ends up on the alternator and usually the radio has static until it dries up. Past that, I don't know anything about your car and it's many oddities.

 

ok that isues with the static sound on the radio every time I put the ignition key started months ago but when the car run after a few minutes was ok, and the same time when I turn right or left is the same with static on the speaker, but after a few days disappear, until I refill the cooling and one day after start again, but I put a T-shirt over the alternator to avoid any accident but we never know, I will follow your advice I will take off the alternator connector and I will dry with alcohol to see what happens after.
so by the way where is the ground cable? is two fuse box one in the passenger side another underhood close to the engine, thanks so much.

 

Ground locations

the one in the back by the battery
the one in the transmission down to the right of the oil filter cap
the one in the rad cradle above the drivers headlight.

 

If the static has something to do with turning the steering wheel then some wiring in the steering column mus be loose or the EPS motor is being weird.

 

Right now I did that.
1-disconnect the black connector on the battery
2- take of the connector in the alternator and the black cable on the top of the alternator connector and cleanup I rubber with alcohol and dry after, I inspect the alternator if any spill cooling but not, is ok.
3- I put it back connectors on the alternator.
4- I test the car battery with voltameter before start the car was 11.65 volt and after with the car idle was about 14 volt.
so that means is not issues with the alternator.
but the static from the speaker continue jus to put the key on the ignition and turn start with that noise even when is running for a few minutes after is ok, is the same when I turn on the signal the sound coming again until I turn off the signal no matter what if is right or left.

so how know if is the ground issues? how to test all ground ?. I replace the spark plug also in this quarantine, BUT that sound is much much before just return again.so any idea pls......

 

Your battery is dead.

 

The 11.65 measure is the battery, it is dead. The 14 volts is the alternator, it is normal.

 

The alternator is over working to try to run all the electrical in the car and attempt to recharge the battery.

 

A bad battery can ruin a good alternator.

A bad alternator can ruin a good battery.

The alternator is overworking, but only making 14 volts. It may be going bad also.
