At the Ocala meet last year we had 7 VX's getting dirty in deep mudholes with standing water on top. PBR did not get in the mudholes but the rest of us did. Of those, 3 lost their A/C and then slowly everything else started to go. It was the alternators. Apparently the voltage regulators were not properly sealed, and since they are internal you have to get a new alternator. Dealers want $600 or so for them. This failure happened to VX1 (Scott), Frank, and myself. While Scott went through some holes multiple times, Frank and I were less gung-ho and still had the problem. Joe Black, Niv and Alex (-x-) were unaffected, and Alex went back for seconds and thirds and maybe fourths at some of the holes. So you may be fine and you may not if you get the alternator wet, but we had a significant ratio of alternator failures (3 out of the 6 VX's that went swimming). It is also mounted pretty low which doesn't make much sense for this type of vehicle. Just something to be mindful of. Definitely don't use a whole lot of pressure up under there.
P.S.- It happened to two 99's and a '00. I don't know if the 01's are safe from it, but we didn't have one fail. We had unaffected 99's too, though.
