SupporterArrived in Brisbane 2 days ago from Cairns with van in to D3td.
Car has been parked in the van park for 2 days took it out today shopping, started fine nothing to alert drove 8klms, parked at shopping center for a couple of hours, came out drove probably 1klm. Fuel up started and drove about half a Kim to traffic lights, went to take off no power big "F" on the dash, travelled 50 meters suspension fault flashed up and everything went dead !
In the middle of main intersection, automatic reaction went to put on warning flashers nothing ! Stuck it in park - bad mistake once in park could not take it out without power, could not push the vehicle, locked in park, no power no nothing !
When I could with safety, cars going everywhere I put a multimeter across the battery 1.5 volts ! YES you read that correctly 1.5 volts at the posts !
Flat top from RACQ got there in 6 minutes, pretty good I thought, put a power pack on got it out of park loaded and moved me 50 meters, called a service van. It is Saturday, service vehicle was pretty prompt as well must be a quite day for them.
Voltage at this stage was 7 volts, alternator stuffed, battery flat he announced ! Can't be says me it started fine 3 or 4 minutes ago at the servo it is not dark no lights on. Ohhhh.
Anyway we jump started it, voltage sitting at 12 with motor running lights on or off made no difference to the voltage so alternator must be doing something.
Cut a long story short we drove home 7.5klms, by now it was dark lights on, no probs, he followed us to make sure, voltage sitting on 12.4 when we arrived, eventually turned off, 30 minutes later voltage was 12 volts at the terminals.
Battery is 5 months old, at present on a jury rigged charger from the van, but it will do it.
What would take a battery capable of starting the vehicle normally to having only 1.5 volts reading in 500 meters ?
Has to be battery surely ? Anything else in these vehicles capable of doing that ? Battery that came out 5 months ago was 7 years old, changed because I was going very bush, and thought it was too old to trust on that trip.

I normally keep a tidy house when it comes to the maintenance on my vehicles,
but the last few weeks have been horrific in regards to battery and alternator issues for me.
Batteries dying, fire in 'Fred's' alternator and a supposably new alternator had it's regulator go faulty, along with several calls from customers wanting repairs to their electric fence units ! What is going on, has there been a magnetic storm?

SupporterUpdate.
Using a smart charger from the van 30amp. Through 5 meters of dual core 6mm cable (4.35mmsq.). Wire ran quite warm to start with, not hot but warm, charging at 12.8volts within the hour the charger had gone to float at 13.8 having been up to 14.4. Switched charger off overnight.
This morning bettery still reading 12.9 volts turned on lights etc and instantly down to 12.0 volts. Started fine all normall, but with engine on reading 11.8 volts - dam it is the alternator - started to increase voltage and within a minute or around that it was at 14.3 volts, every time I started did the same thing, is that normal ? Seems to take a long time for the alternator to boost the voltage or as I suspect the battery is shot ?
Take a bus ride today worry in the morning Sunday not the day to get sense out of anyone.

Hi DD and that is very "normal" for a D3 or D4.Originally Posted by Glynhouse
When you first start the motor, the ECU keeps the alternator off ( free wheeling ) while the ECU ( BMS ) monitors the battery.
After about 30 second in a D3 and anything up to a few minutes in a D4, the alternator then starts up and your voltage rises.
While the battery may be the problem, to flatten your battery in such a short time “while driving” would make me suspicious of the alternator.

Out of interest what brand of battery did you replace the original with?

Had some strange symptoms on mine, stereo shut down (aftermarket) then all ok.
Same thing happened again but this time faults continued until it wouldn't change gears then would not start.
Alternator shot.
Yours could be on the way out?

SupporterThanks DS. Was hoping you might pop in, how would an alternator take a battery that low after a perfectly normal start only 500 metres before after fuelling up ?
On the service guy's fluke meter he was showing 19 amps into the battery at idle with the lights on, but it has developed a whine in the motor somewhere in the last few days.
Still suspicious that the battery will sit at around 12.8 volts overnight but drop to 12.0 with just the lights on in a matter of seconds.
Terry it is a Delcore 60038, as used by the L/R dealers up here. Cost me $235.00

SupporterThat battery seems to have a very low CCA compared to the vehicle requirements - it only has 650CCA where I thought 850-950CCA was needed.

Don't discount the possibility of a broken internal connection in the battery - good one mnute, dead the next.
