Battery warning light

[Grappler]

The wife rang from town to say the red battery warning had come on with the RRS TDV6. She did'nt get any warning messages.
She had a look and the belt was OK, so she drove the 20 kms home (headlights on).
When she arrived I checked the battery at about 12.9v resting and 14v running. Terminals and earths look ok
Pulled and checked the fuses -all OK
Scan with the faultmate revealed P0625. (generator field terminal circuit low.)
checked the charging circuit- looks OK.
Cleared the DTC - Red battery warning light now OK with motor running
Tomorrow will tell if a new alt. is required

Anyone had similar experience?

A week or two ago the Local Land Rover blokes said the Alt needs replacing but not due to output as its charging perfectly... I am unsure of the diagnosis (from memory) but although it has not caused any further problems, Forum advice states it will crap itself eventually causing a possible 'stranding'.

I am scouring the net to find the best option for replacement but as I am only driving locally at the moment there is no real panic. I would not go too far from home at this time.

But the bottom line is it running fine and has done for many months .. I thought it was just another electrical 'glitch' ...

like an intermittent Cruise control (usually 'refound' by a restart), along with an extremely intermittent fault in the Fuel Guage (sender) shows empty for a minute whenever it wants (sometime three times in a row ... then not re appearing for weeks) and doesn't seem to have anything to do with Level in the tank!.

anyway each will be rectified in order of serviceability /priority.

There have been quite a few threads on alternators/batteries in recent weeks. Cold weather and age of vehicles. It seems some show the red battery light on the dash, others don't.

Coolum - the intermittent cruise control is probably a faulty clock spring. It is also in the path for the steering wheel stereo controls, and the air bag. Let's hope you don't have an accident to find out it doesn't fire. :o

Exactly what happened to mine, literally last week.

Alternator time - Pretty easy job, and $600 delivered for the Denso unit from Karcraft.
Speak to John he is a good bloke.

I did mine last Saturday. Took me 45 mins to change, and I am no mechanic.

Do it before your battery is destroyed, and the Alt will randomly fail big time even though it shows to be charging the battery now.

The red battery warning came back almost straight away.

Karcraft are out of alternator stock till early August.

I have set up an Ultraguage with an alarm to sense excess voltage.
At the moment its charging too low. With a maintenence charger attached when she is in the shed, and avoid night driving, I should be able to keep the car operational till I can get a new alt.
If the alarm goes off it will be a tow.

Ah maybe I bought the last one off the shelf..

Keep us up to date with how it goes.

We've had the battery low voltage warning since the car was delivered. I ususlly connect the ctek every month for a couple of days. Is there a resistor fuse available to bump up voltage hence charging battery further. I know this was a mod available on our Prado. Since the battery on thst was always low too.

Changed out the alternator today. Found one in Perth. Like rg30gtr said it took 1/2 an hour to remove and 15 min to install the new one. Cleared the fault code
Battery now charging at full 14.5 volts and no red warning light
