The altenator is easily accessable if you get down and lie down underneath the machine. From there you can easily check the altenator tension and condition.
If you want to properly inspect the “Exhaust system” for “No cracks” you will have to lie down underneath the machine anyway. Or are you expected to view it from the lower cowl door on the right side? If this is the case then you would need a fibre optic camera in your toolbox!
