I just had a search for them. They are open to the weather and flooding as well. I also think they would be too big in physical size, but 200 amps would be nice though. I also found bits of chopped up water weed and reeds in my alternator, which was disappointing. One section of track sloped to the D/side and a sheet of water came over the bonnet. There was no way to turn back, so it was do or wait a couple of weeks for the water to subside.
