Ok...lets start with what engine/alternator  :D
Does the belt slip when water hits it?
Have you tried waterproof conductive grease on the contacts?  

[landymad839]

well its a 2.5TD with a seira alternator  

no the belt is tite and we have put conductive grease on the contacts

when we put a battery tester on when the engine is running it has no charge coming from the alternator  :(

For how long does this no charge last after water bath?
I would say the alternator is shot, a new one should be cheap enough though.
 :roll:

[landymad839]

i wont charge again

we have to put a new alternator on most times we come bk from off-roading  

thanx 4 that m8

What sort of amp hour are these alternators?  I would say you are burning them out nothing to do with the water...they don't like wd40 though
 :shock:
Try testing them before & after wading, also see how hot it is getting :?:
Could be your battery killing the alternator tool :shock:

[landymad839]

i think there 65amp  :?

i dont put wd40 on i put seler but it doesnt dry hard

ill have to get another battery

thanx 4 ur advice

65amp should be fine as long as you are not doing allot of winching...before you change another get your battery checked at ATS or similar
