Starting problems

Hi All

Starting problems
We recently took our 95 Series LC in to Toyota in Nowra for the following as general maintenance before we head over to south America:
• Service
• Replace Condenser
• Replace Glow plugs (bosch replacements)
• Replace Injectors refurbished

On getting the car back its now having starting issues every morning.

On checking the battery meter the voltage starts at 12.8 and drops to 11.8 / 12 as soon as I turn the key to on and stays there, on turning the ley it does not start until I engage the third spare AUX battery in the back.

I have taken the car back to Toyota, they have said they have:
• Tested the batteries
• Check the Draw while the vehicle is off

They say they do not know why it’s happening and have said there not much else they can do.

Once the car has started its good for the day, however on each occasion the voltage while in the on position drops a quite a bit

My initial thoughts are something is wrong with the replacement glow pugs that’s causing a draw, however the glow plug light is going off very quickly (maybe too quickly) when turned to the on position.

Is anyone able to help us diagnose the issue or has encountered this before?

Many thanks

Martin

What does the battery voltage drop to when the starter motor is engaged?

Anything less that 10Vdc would be considered as a failed battery if its no load voltage is up around 12.8Vdc. Simply having the car at 'on' will not generally cause enough load on the battery to show the failure. I discharge test with the appropriate tool over 15 seconds would give you the information also.

But it sounds like a main battery issue...
