Hello community
my first MP3 was quite fast defective (rainwater poured into the casing after six weeks) and due to high shipping, insurance, time costs and toll declaration it was replaced with a new one.
The second one I received did rust on the wheel when received (and short afterwards exchanged by the EU dealer), but I tried this one: and it hummed quite loud compared to the first one even without a load.
Now I'd like to repair the first one: water was removed, dryed and opened for about 3 month now. As it was rain water the damage of the electronic maybe minimal. What distrubed me was the fact that the windings itself are not locked via some dipping paint, some humming is normal and corrosion is quite normal for the stator plates.
The place where the water came in was a dark cavity in the aluminium shell, which is now sealed (PU).
Question: is it adviseable to conceal the windings (and stator) and why did GM not manufacture it like that? The additional weight doesn't hurt and the protection & advantage is enormous.
I'd plan to use solid dipping paint like epoxy and hardened via 120°C afterwards (electronic removed) or via modern US9400 based on polyurethan
Cheers
Sam
