D3 Red Battery light on dash - why?

[rb30gtr]

Hi Disco experts...help needed once again.

After a big day trip on Saturday, I started the Disco on Sunday only to notice the Battery shaped red light on the dash.

So as I figured, I checked the batter and sure enough it was very low in charge and not seemingly holding charge.

I tottled down to battery world and put a new battery in.

Dash light went away.

Then on the way home it came up, went away and then came up again with the new battery in.

So to assume I would think it is the Alternator not sending enough charge, Any insight from Disco owners would be greatly appreciated
Would it be water causing an issue, is this common?

Water itself shouldn't be a problem but mud would be. Hosing out the alternator (not while its running though) may overcome the problem if the brushes aren't badly worn from mud/dirt. Alternatively one or more diodes or the regulator may have been cooked.

Great thanks,

I'll get at it this afternoon with the pressure washer and see how it goes.
It is not making any bearing or brush noises when running under load..yet

Cheers,
Ben

Same issue for me awhile ago and have posted about it.

D3 issue only.

Light comes on intermittently as alternator diodes fail then they short out and it costs you an Alternator and a Battery.

Highly recommend you don't risk your battery and get the Alternator checked out A$AP.

Will do mate, thanks for the info.

My alternator was around the $500 mark. Basically started her up after a long trip, burnt smell, whirring noise that changes with engine speed, battery light on.

Checked charge with alternator ~11.5v.

Was enough to start the car and drive the next day ~20km. Died soon after, started with numerous bongs, then Christmas tree lights, then trans started slamming into gears.

If this happens to you and you expect to load the car onto a ramp, etc, try not to put it in PARK, as it will then lock you in park and you won't be going anywhere. I think garrycol had some advice to get it back out again which involved removing part of the centre console.
