There must be some short somewhere, it only starts because the battery does it and when it tries to turn on the fuse burns and that is because the alternator goes to work ... I think that being an electrical failure there is only take the alternator / regulator to check. Check if it is the only blown fuse, maybe there is more. The alternator does not work by itself, the engine pulley puts it to work, check if the terminals of the engine, if there is a burning smell or something is seen, you should check all the harness that reaches the distributor and the battery
Hello Matrikx, today I took the alternator to check it turned out to be the regulator that was sending much more voltage (19 volts), that regulator was new only one month of use, well I am also checking all the wiring, I wanted to ask you a question and help me with this, the alternator is adapted and the regulator connector is up, and there it receives a lot of heat because it is close to the manifold, the heat it receives could be causing that more voltage has been put to general.
Oka, then we were fine in the diagnosis, but I got a doubt, the regulator is not part of the alternator? Why the adaptation? You didn't find the original or a similar one? That the regulator is already included, I say ... could you upload a couple of photos to see how it looks?
Hi Matrikx, of course the regulator is part of the alternator, the alternator that is mounted is a replacement for the original Huyndai, it is from a Kia Rio, it is the same thing that I change is the position of the regulator connector, the original is down (very far from the exhaust downpipe), the one that assembles the connector is facing upwards (very close to the exhaust downstream), the heat burns the connector and the cables warm them, but the regulator is not burned by heat. I don't upload photos because I don't know how to do it.
Well, it seems that is the problem, the heat damaged the regulator, and there is no way to change it no more, there is no other, and it will happen again if you do not put the original or another that is not close to the manifold. Another thing you could do, meanwhile you get the original, is to put an insulator in between. There are some gaskets that are put in the manifolds or leaks, they are precisely to seal the joints, resist high temperatures without problems. But of course, it is a momentary solution. I hope I helped you friend !, Regards
