unusual sounds, acid smells, temperature variations, etc.

Troubleshooting procedure
The following approach should be used:
-System Inputs. Check that the system has the correct power input;
-System Outputs. If there’s input and no output,then you have already
isolated the main problem;
-Fault Complexity. Most problems usually turn out to be rather simple.
Start with the basics;

Failure Causes. When a fault has been isolated and repaired, try to
ascertain why the failure has occurred.

proper use of the multimeter and doing tests such as continuity,
resistance, voltage and current test.
