I think these style of alternators are pretty much standard everywhere on newer cars as they assist with fuel consumption, "turning off" the alternator when it is not needed.

If it's is being told wrong then the sensor shunt on the battery is faulty or there is a faulty connection or wire in the circuit. If the ECM thinks the engine needs help it will command the alternator to drop the voltage it is generating to help relieve the load on the engine. You could probably disconnect the battery sensor and create a little circuit to simulate demand on the battery and see if the alternator output is varied by the ECM.

Martin, I just sent an you email with a question "what can I do", well I have added into the weekly Resting Voltage Table all the refuelling dates and the octane and the Oil Change dates and grade of engine oil.

The one that makes the difference is the oil changes.
After the first oil change in August last year a drop in battery voltage.
After the second oil change in February this year a slight increase in battery voltage.
Could the oil be too heavy for a new motor? In August 10W30, in February 5W30.

Should the question I am to ask be, can they use 0w16 or 0W20 oil??

For market code E02, E22 and E54
It is recommended to use engine oil of SL, SM or SN grade.
Select an appropriate SAE oil viscosity according to the chart [A].
0W-16 oil is the best choice for good fuel economy and good starting in cold weather.
Except for market code E02, E22 and E54
It is recommended to use engine oil of SG, SH, SJ, SL, SM or SN grade.
Select an appropriate SAE oil viscosity according to the chart [A].
0W-20 oil is the best choice for good fuel economy and good starting in cold weather

That's an easy one, Australia is E24, so I will ask for 0W-20 Oil on Tuesday! :woohoo:

You put 10W30 into it? Or the dealer?
Does no-one read the manual anymore?
I don't understand however, why they have singled out the UK, Germany and Israel to specify 0W16, I mean it's not like the UK has a similar temperature range to Israel, and whilst we do have a similar climate to Ireland, the Netherlands and Denmark, they get to spec 0W20??

I suspect the K15B was designed to run on 5W-30 and the 0 weight oils have been introduced where necessary to keep emissions down. Take a look at hot 0w16 and you wouldn't risk it on a sewing machine. Chris

Three different dealers, 3 times, PD, 6 & 12 month services! And they wonder why I don't want to go back!

I just posted the question on the Aus JB 74 Facebook Page, www.facebook.com/groups/1196794093818351/ no they don't read the manual, tyre pressures are another one they miss!

0W16 oil over in the UK is around £12 a litre.
I think I'll be using 0W20 in mine, Shell Helix Ultra SN 0W20 is about £9 a litre but there's a place in Darlington, Smith & Allan, that do their own label
Momentum C5 SN 0W20 for £11 for 5 litres, I reckon it's the same stuff as the Shell just they buy it in bulk and repackage it.

That's a good price. Thanks for letting us know.

Penrite do an 0W16 if you really want to go low

Hi Martin. Regarding your post about disabling ESC (ESP?) manually. It sounds like a good idea for gravel roads and beaches where you might be above 30km/h but don't want the Jimny to be losing momentum.
Are you referring to the OBD connector, and is it a momentary connection between pins or does it need to be held shorted?

Cheers, Mike
