Unless specified otherwise, all the measurements must be taken with the boards fitted, together with their connections!

Remember that the first test to be performed is the VISUAL CHECK!
The visual check reduces troubleshooting times and directs any subsequent tests towards the damaged part!
In general, points to be visually checked are:
- input filter area
- traces of smoke on the inside of the bonnet
- power and signal connections
- overall condition of the boards
Caution: when the machine is connected to the power supply, the main switch is live, regardless of its status (open or
closed)! It is therefore important to unplug the machine before touching any internal part of the power source!
Wait approx. one minute before carrying out work on the internal parts as the capacitors may be loaded at high voltage!
