301/302 panel malfunction

Post by George » Fri Oct 18, 2019 2:39 pm

Dear all,
I am a new member, so please excuse me if I am opening a topic, which you have already discussed.
I own a 2007 39 Cruiser, which has given my some heartburn, but nothing I have not been able to fix sofar, until now.
Here it is:
My navigation lights suddenly stopped working - bow, stern, masthead and steaming lights. The deck flood light works, even though it is located in a joint light with the steaming light, but is controlled via a separate circuit.

The light bulbs are OK - checked. Cables are OK. Fuses are OK. Relays are OK

The yacht is a 2007 Bavaria 39 Cruiser, equipped with the standard 301/302 electrical panel, which indicates faulty circuits. When I remove the respective fuse for each light, I get a fault signal (blinking indicator). When the fuse is returned, there is no fault signal, but the lights do not come on.
I'm quite competent with electrical "stuff' and have basic electronics knowledge, but could not figure this one out, A technician from the marina came, and confirmed my findings, without being able to assist further.
Any advice will be highly appreciated. Thank you in advance!!
