An update, late this afternoon i went to an electrician that told me the problem is either the ECU or the... i forget the name of this part, the one that let the air in in response to the accelerator, in gasoline es throttle body i guess?

Now the problem is only when I turn on the ac

Ohhh excellent, thank you for the fuse info and double thank you for the hint, i tought the opposite but it does have sense how you explain it

Yes, it is for a relay for an additional horn. I want to complete the missing fuses in thebatery box, do you know the rating/amperage of those fuses?

Good morning guys! Could this problem of the voltage going up and down be cause due low oil? My car burns oil, (pending job), and may be a coincidence but I did complete one liter of oil and while driving, the problem appeared only for a brief moment and with the ac on

Thank you very much for your help

Yeah you are right,i will give it an eye tomorrow

It came on a two months ago but due the brake light switch. Then never back again until today. Everything would point to the alternator or its regulator but the problem still persisted when I removed the alternator form the equation.

Yes, i am aware of th three function of the glow plug lights (brake bulb, brake switch, or general electrical malfunction) Yes they are working. I finished working in the car for today. I turn on the car then remove the battery, the problem was there, I turn on the car and remove the alternator, the problem was there. I removed all the fuses but only the vital for engine keep running, and the problem was there.

I forgot to mention, the ignition wire signal is on

It is new (two weeks) and it was charging yesterday (since I left the car in the garage for two days while I do the wires stuff, I put the battery to charge overnight

I will do that now and will try

Yes, and it goes away as it should, BUT past weeks has come on randomly couple of times

An update, I went out for a new belt. The up and down of the electrical sistem is partialy gone BUT when I turn on the AC it comes back, when I turn it if it stays for some seconds...

That is very hard to get in this country, an automotive electrician. I did a little experiment, I did remove the accesory belt, so the car running with the battery alone... and the heat in the wires gone BUT the lights still up and down

Uh, I just installed everything, all good but the issue with the lights continue. One thi g I did notice is that the two big black wires to the positive pole of the battery got hot in just 3 minutes., not hot that I can not touch, but very warm

I will take advantage i am dealing with wires and will install a small ground kit

I am working on that today, i will today later or tomorrow install how i should be,

Uff very bad, mine are bolted.

organizing the cables (the two small wires to the alternator were not working properly, the connection was faulty at the connectors you mentioned earlier, i will bypass them. I found this black, wire disconnected, it looks factory, not adapted and it was cut, not burn or ripped off... what it is?

yes yes it does make sense, i got it, and yes i found 1 2 3 in the other side too, i wil make sure it hass good contact with some contact cleaner and some adjustment, thank you!

The yellow one is a auxiliary headlights i installed ;-) And now i know why the fan works with that cable disconnected, check this pict the wire i marked with green is the ne supposed to be at the fuse 8, it is connected directly in the upper position of that.. i dont know the name hehehe, so it is not protected

oh!! when i bought the car, my mechanic sid the module or the fan had the low speedfunction damaged and charged me for a new fans and the module that controls those fan, the fans works good, low and high but then.. that wire....

i do not have the cover :-/ it is in the 8th position

Hello it has 3 wires
