From the sounds of it, it's one of 3 possible things. Alternator on the way out, battery not holding charge properly or the starter motor pulling way to much on start up which in turn kills the battery.After a 3hr drive it started ok just had no aircon, but a day and a half later it just turned over.

What happened in 70,00 km that would cause a stater motor to start failing? Possible but not likely.A battery only needs to go flat once and they can be buggered. Since you're saying you need to recharge it due to long periods of not driving, plus dropping below 9 volt at cranking, I think it's a simple case of a battery with a crook cell. If you're unsure or simply want to investigate furthur before dishing out your hard earned, get it load tested. Any auto elec can do it in 5 minutes so shouldn't cost much. But it is very possible to have a battery showing 12.9v under no load that keels over when a load is applied.If possible hooking up your charger to the car whenever you're parking it for more then a couple of days would be a good idea. 1 Link to comment Share on other sites More sharing options...
petchyboy Member 76 Member For: 15y 2m 28d Gender: Male Posted 10/11/15 11:55 AM Author Share Posted 10/11/15 11:55 AM (edited) Hoping the starter is fine, 70% of my driving has been highway k's so not many starts frankly, last tank of fuel lasted 11 weeks! Charger is on every time I'm home, I can live with that. No aircon coming into summer in south west Queensland I cannot especially with a trip to Melbourne in 3 weeks. Thanks for all the advice guys, off to the only auto elec in town tomorrow.....it's gonna hurt Edited 10/11/15 11:57 AM by petchyboy Link to comment Share on other sites More sharing options...

petchyboy Member 76 Member For: 15y 2m 28d Gender: Male Posted 12/11/15 08:38 AM Author Share Posted 12/11/15 08:38 AM Verdict is partially in. Battery was certainly screwed, not even close to being passable, so that's replaced. Cheers to the shop that told me it was fine!!! No more business for youThe other possible issue could be the alternator loosing a phase when it gets hot on long trips, so I'll see how it goes over the next week without using the trickle charger. Alt puts out a good charge cold though and I wasn't game to fork out 500 bucks to get it checked or pay a grand for a new one installed! Bring on the 1600km trip to Melb in 3 weeks. Fingers crossed.Thanks for all the suggestions and input Link to comment Share on other sites More sharing options...
