G'day Rod,

Just read your signature line - is the Athol Hedges roof a type of safari roof?

Kind Regards
Lionel

No Lionel, its just a steel roof with rounded corners and its the same height front to back, unlike land rover roofs that slope down at the front. They tend not to last too long coz they suffer from rust coz they werent really rust proofed.

Cheers Rod

Hello All,

I heard back from the USA Yanmar Group - word is that the original parts manual states that the battery to quote "calls for a N70Z battery" which is what I have with the N70ZZ. I also found somewhere else that the battery is specified just as 12v 75 ah.

The Century N70ZZ is rated at 85 amp hours so it is better than the specifications - although the specs do date back to the 1970-80.

Some of the latest Century Ultra batteries are rated at 95 or 100 amp hours. When I checked the Century bank for Land Rover Series III Petrol and diesel 109s the current battery is not coming up as the recommended ones - only the "Ultras". Yes they the dearest ones - funny that!

Well at least something is right with the N70 being fitted to my Yanmar tractor I will trace the circuits back from the battery after I replace the earth lead to find out what else is possibly amiss.

Kind Regards
Lionel

Don't know if it's been covered,but a static charge doesn't mean much. OK,it needs to be@12.6 v but you need to check it under load. The battery could have a n open circuit cell. Good voltage static,0 v under load.

Lionel,
It seems to be a bit of a secret but Century had a bad batch of Overlander batteries & your purchase date seems to fit. I had one fail in less than a year & it was replaced under warranty after being sent back to Century. I think that was done in Feb last year. I crossed the Simpson later in June & because I run 2 batteries parallel, I never noticed that the replacement battery had failed too. As I bought the battery from a specialist shop I went back with the second battery & when I said that it had taken some horrible corrugations & the Simpson (5,000 klm) it was swapped no questions asked.
Naturally I was reluctant to settle on the same model ( N770Z 4WD Overlander) however the owner assured me that there was some "design Improvements" done & that there had been a problem with some earlier batteries.
I've done a few high plains trips with no further issues.

Regards, David

The battery is a Century 4WD Battery N70ZZ 4WD-760CCA.

What battery jump starter pack would you recommend so I can at least get the damn vehicle started?

When I put the battery back on the Battery Fighter and checked it a hour later, the light was back on constant green. This equals fully charged! Something is going amiss somewhere. I will disconnect the battery and put the Battery Fighter back on to see what happens.

Next time I hope to have the recommended battery jump started and be able to at least get the vehicle started so I can achieve something.

Kind Regards

I have one of these, these little mini jumper starters are brilliant, not this exact model, but close.
