My alternator as dumb as it gets and I don't have access to it's specs right now.
I keep it and I have spare one.
Choosing between 30A and 50A. Leaning toward for extra $100 for 50A
I know I can configure to lower amperage throughout in configuration to stay on the safe side. The same time I want fully utilize charging capabilities.
I can use IR temp gun to take temp measurements.
I want to keep it as simple as possible to have simple ON/OFF swatch to isolate starter battery in case of alternator overheating. No relays, no automation.
Questions
Where on alternator honest points? What acceptable max temp?
Does it make sense to have more permanent solution with temp sensor and gauge?
Where and how to mount sensor? Share your ideas please.
Is alternator overheating is subject of engine RPM's?
Appreciated for your input.
Thank you.

Again ,but if you have mass production,original to engine alternator is not dumb. this alternator for example Mitsubishi 115A spend more
money in design ,testing this alternator vs total valid company produced outside alternator.
if you charge Mitsubishi alternator on 600 rpm he lower down to 70-80A charge when temperature fise hi lower more charging current to 0 if needed. if in engine compartment over 160°C hi have 0 charging.
Also you must know modern
diesel engine want be around 90°C some need working temperature around 96°C
Generally, the operating temperature of an
diesel engine should be between 190-220 F degrees
alternator have working temperature 60-150°C some over 200°C
if you have dubt on market you have lot
water cooled alternator 100-200A your engine is around 85-90°C buy this 20-100 cm pipe and don't worry.
