Yeah, the early mark2 Ducato (94 on) had the wiper ducting drain straight on top of the battery, which overflowed and coated the chassis leg in battery acid!!! The modification was to move the drain as far as possible from the battery . . ie, over the gearbox vent, which washed the grease off the external linkage and seized it!!!
