What do the numbers mean on the fusible link cover?

It is technical info for the make up of the components. This is how I would interpret it:
AM1 main - Indicates the circuit (alternator and other circuits)
1.25B - should be the wire gauge, in this case it would be 16 AWG
2.0L - I am not really sure maybe load capacity

I am sure @jonheld, @Malleus or another electrical guru can chime in an correct me if I am wrong and possibly fill in the missing info.

FL AM2 0.3P=Fusible link AM2; 0.3mm PINK (30 amp) grey connector
 
I am definitely not an electrical guru...but I sometimes play one on the internet
 
Thank you for the information. So the number is like the millimeter size of the wire and the letter is the color.

Correct. The jacket color indicates the current rating.
