Manta RS4503 Ontario Radio Not Turning On: Connection Issues, Voltage Drop, Blown Fuse

Hello. Sorry for the mistakes because I'm new to the forum.
I purchased a Manta RS4503 Ontario radio. The radio does not turn on after connecting. Connected according to the diagram, black cable to ground, yellow to DC 12v, red to pulse on ignition. The radio is not responding. The meter shows that the car is sending voltage. I also connected the radio to the rectifier, the fuse blows every time. After connecting without a fuse, the power consumption is such that the voltage on the rectifier drops. What could be the reason?

black to ground (minus) and yellow and red to plus, and if the radio is operational, it must work.

red to pulse on ignition.

not the impulse, only + 12V which appears after turning the key and which powers most devices in the car.
If you gave this impulse to ignition, it might not survive depending on the car

So if I connect the radio to the rectifier, then the red cable + 12V should also be connected to the plus?

I understand "do not survive" burned out and thrown away? Despite fuse protection

Yes
Yes
you wrote that you connected without a fuse

And not a rectifier, but a power supply or something that gives 12V-14.5V but DC voltage without ripple, or a battery or installation in the car
