Electrical - Charging problem

[stevh0]

Last night i accidently went throught a huge freaking flooded road. the problem was not crossing the road but at the speed i hit the water .. must of been somewhere around 100kph.

If parked the water would just be under doorlines, yes the road was flooded.

As i hit the water I realised oh crap .. this is too fast .. maybe it was the wave that went over the car that gave me that idea.

so anyways. about 20km later I noticed my battery light and my Cat light coming on on the dash.

When driving with the lights on there is a huge load that that car just cant handle. it would almost die if i drive with the lights on too long. I drove about 30km without lights at 01 00. thank goodness for road lights!

any ideas where I can start looking?

Alternator?
Fuses?
battery?

Thanx guys

Your alternator is dead mate dismantle it and have a check your diode and Regulator is out of use.

Sounds like the alternator but also check the leads and dizzy cao as they could also cause this when wet.

this is why i love this forum. the response is amazing!

I jumped the car off the Wr450, she started after i checked fuses and retightened the battery clamps.

I also sprayed the belt with some dressing. Started chirping, but the voltage meter runs at 13.13v

With the lights on it dips to 12.44 on idle.

will take it for a drive to charge the bat and see how it goes. If the voltage drops belove 11.5 with the lights on.. I might have a slight sittuation.

took it for a drive it drove fine.

but its losing power somewhere.

the car runs perfectly with no battery leads attached. I dont have a multimeter, but i can almost say that there is no current to and from the battery leads.

any other ideeas?

13.13v is a bit low.. it should produce more than 14V (mostly around 14.4v)

Ive had squeeling belt for ages. It needs tightening I know that. Now im figuring, that i really need to do that.

Its such a mission to get in there with limited tools. Eeek!
