HiCustomer welcome to

Per the B & S site:

Transfer Switch Fault (FC_8)

This fault is indicated by fault code FC_8 and eight blinks on the LED indicator (if transfer switch is equipped with fault detection).

The most likely cause of this fault is a blown fuse in the transfer switch.

Thank you

All you have told me is what the manual says.The fuses have been checked and are fine,but this was done after my post as i didnt have a multimeter.
