Thread: Battery light coming on when fording...

It's usually caused by belt slippage when it gets wet, rather than an actual alternator problem.

Mine does the same thing.
Has done it for years and usually stops as soon as I exit the water. Never been a problem and I must admit I hav'nt gone looking to hard as it is still going, so I am prepared to leave well enough alone.

I agree with both of the above.

try saddle soap on the belt or rosen u can find it at horse equitment places the belt grip you buy in the spray tin washes off in water the rosen stays sticky

But wont a "sticky" belt pick up rubbish?
just live with it.

sometimes the saying if it aint broke dont fix it ought to be listened to. This is perhaps one of those times.

The two things I would look at if I were to play with it is replacing the belt if it is old and perhaps the tensioner pulley if it is weak.

Dont mention the f@#d word and it wont happen again .
