Right alternator and rain

[roger]

Anybody have tips/tricks for keeping the right belt from slipping in the rain?
Ideally, without AC you could move the alternator to the same place as the left one and get it out of the rain, but I started down that rabbit hole and realized unless I was doing a whole fleet the effort wasn't worth it. How about a fatter belt (like the ones Piper sells from Gates for the Cherokees) instead of the dinky little Lycoming belts? Or just keep em nice and tight? We've been using the torque/slip method of setting tension and that has helped a lot.

We keep the left tensioned to 84-107 in lbs and the right tensioned from 108-132 in lbs

Haven't seen any issues at this time - our aircraft are not equipped with AC

We keep our belts tensioned and haven't had any problems, out aircraft all have AC but it doesn't get used all that often, mostly just for a little while on the ground.

We will try the higher number for the right. I think we are using the lower set of numbers for our right one.

I fly regularly into fairly heavy rains (I'm in Suriname, near the Equator) and have never seen fluctuation... We just replaced both alternators and belts, the right one is a tad tighter. I have AC (obviously NOT working) so the alternator is exposed.
