question Indicators and break lights not functioning on Zetor Proxima 6441

I own a 2008 Zetor Proxima 6441. Recently I noticed the indicators had stopped working along with the break lights. I checked all the fuses to discover one had blown. I replaced the 15A fuse and when
I switched on the hazard lights afterwards to check if the problem was fixed the new fuse blew immediately. Any idea what may be the problem and how to correct it?? All the other lights on the tractor are functioning correctly. Any advice is greatly appreciated, thanks In advance.

Brake lights often give trouble regardless of make of tractor. If you indicators blew the fuse, I would start by checking the lamps.
