Hello companions I have a doubt about an ammeter ... what is acquired but it comes with a thick sheet between the + and - terminals .... you have to remove it or not to connect it in series with the greeting of the negative of the rectifier bridge which in turn goes to a fuse and the fuse to the ammeter ... which is the question I have is here in which terminal goes the entrance and exit and laminates it if it is necessary to remove it or not of course greetings and thanks

Hi Maxima Madness The sheet you mention, is called shunt resistance, what it does is that the majority of the current passes through it and a small amount passes through the ammeter. If you remove it, the ammeter will go to full scale, and may be damaged.

As Ennio tells you, that sheet determines the intensity that will pass through the ammeter. You cannot or should not remove it. As you say it is a thick sheet, it is assumed that the ammeter will measure 5, 10, 20 or more amp.

ok as you are telling me not the withdrawal, the ammeter is 10A .. The terminal titene + and - which I connect to the negative of the car charger .. this negative comes from the rectifier bridge and comes in series with the fuse which it connects to the ammeter but in which of the 2 terminals in positive or negative? and without removing the shunt as I mentioned
greetings and thanks

You can put the + of the charger to the + of the amp. and the amp. to + battery. The charger - to - the battery.
It can also be the - charger to - amp. And the + amp. to - of the battery. And the + of the charger to the + of the battery.

Someone has measured a transformer with multimeter ... and armed one and measured volt with the multietro and great 14 v. But I need to know that amparage was measured by the multimeter and the fuse was screwed ... and they are not very cheap to ride it ..that I do as I measure it Greetings to everybody and thanks

You made a short circuit with the multimeter .. !!!
The voltage is measured between the 2 poles, but for the current intensity, you must put a load that limits the current. If you know the power of the transformer and the voltage, you can calculate how much is the maximum it can deliver.
To measure current intensity with the multimeter, you must insert it between a terminal of the transformer and the load.

As Ennio tells you well, you made a short circuit, with a little luck you only burned the multimeter's fuse. The intensity that the transformers give is not measured, because the transformers are giving intensity ... until they burn.
