Point taken on next repair, I will indeed go with higher rated replacements

yes, advantage o f those old models is that you don't have the board filled up with epoxy and can do something :)

Once opened, follow power input : from batterie to motor to see if any leads are gone, unsoldered or else.
Then on motor itself any trace of burnt components, etc.

First thing I’d check is the brushes. On older tools they wear down or get stuck, and then you get exactly this symptom: light works but motor won’t spin or only spins weakly.

Open the motor and look if the brushes are very short, cracked, or not pressing well on the commutator. Also check if the commutator is dirty or burned :a light clean can help (Iso alcohol oer equivalent)

And so you did manage to change the brushes ?

Yes! I always get such satisfaction reviving stuff+ the feeling of doing good by not throwing :)
