Hi guys.

The file is 100% ok
but the dash worked for a few minutes after the replacement of the mosfet irf3710 and then blackout again.
So i used a new mosfet and replaced the 3 capacitors (100uf 50V) but the fuse blowed again and also the mosfet.
I took off one resistor and it as 1,1 ohms so the resistors seems to be ok.
Now i bought the IC 2843B and i'll have to use a new fuse and a new mosfet.
The lights on the dash are very bright.

Could be the transformer or the uc2843b ?

Any ideias ?

thanks.
