Not sure if this is the problem i face but last night i was out, parked stopped for about five minutes to check if i was at the right place (sitting in the car, acc on checking the sat-nav.) When i went to start the car again had nothing but a click, as if i had drained the battery. When in for the night thinking someone could give me a jump when i returned to my car later. At the end of the night bout 5 hours later thought i'd try it just in case, kicked over first hit, strong as. I don't get it. Then again this morning went out to the car and it's dead again.

BTW was an hour drive home last night, thought it would have charged back up at least enough to kick over for todays travels, No good. :-(

Any ideas guys, i really can't afford a new drycell ATM.

First thing you need to do is check the battery is holding charge. If you had nothing but a click there could be problems elsewhere in the line. How are your earth connections? Battery terminals nice and clean? I would say you have a loose connection near the starter motor...

Thanks Tuff, Yeah terminals are clean and tight. Now i get no click, yet nothing in the electrics reset?? Trip puter, head-unit all still hold memory. Normally lose the lot with a flat battery??

This one has me stumped.....

Check charge rate at the battery with a multimeter ALTHOUGH you should 1st try and get your head under the car and give any wires to the starter motor a wiggle...if they are loose there is your issue! I think that's what it will be.

Don't have a multi-meter :-(, All wires seem intact.

No worries. sounds like intermittent starting....Like if the battery was dead, it would SLOWWWWWLY turn over. As the deep cycles have a bigger reserve capacity it would take hours upon hours for them to 100% drain. I've left the interior light on in the diamante overnight (8-10 hours constant drain) and its started first shot in the morning. So doesnt sound like a battery.

Next thing I would do is either ask ask for an experienced member in your state to have a look or worse comes to worse take it to an auto elec :)

Deep-cycle battery for starting?...

Optima's are deep cycle as-well, nothing wrong with using them for starting.

Thanks mate, I got the a deep cyle so i could run i.c.e. at drive-inn and still get out at the end, lol Been to dusk till dawns and still had no probs starting. May have to bite the bullet and take it to the tire place round the corner and get it checked and replaced if need be. I NEED MY CAR!!! lol It starts with a jump but that may have been a fluke. Anyways thanks for the input, I will let you know how i go.

Could of been a fluke, I would take it to an auto elec to get load tested properly, You dont want to fork out for a new battery for no reason at all. Personally sounds like a starter motor issue.

try manually charging your battery.... alternators cant charge flat batteries at best you get a surface charge

Gave it a jump, started first hit. Gonna see an auto elec now. Let you know how i do. Thanks again. T.J.

You'd be surprised how fast a 90 amp alternator can juice up a flat battery lol Unless it is totally stuffed from being flat too long.

actually my training as an auto electrician says that it will give it a good surface charge but because the battery is flat it cant provide the alternator with the power it needs to properly excite and hence charge the battery. if you run a dual battery system and one of the batteries goes flat then the good battery gives the alternator the power it requires to excite.

Ok, Update. Couldn't find an auto-elec open locally so dropped in on bob jane. They did a battery check and said batter fine pumpin out 12.8 volts with engine off.
His opinion was maybe ignition barrel could be on the way out. Hopefully will last the weekend and i'll get it to the mechanic in my street at work on monday :-)

3rd gen alt's are 110A though arn't they?

I'm only new to Magnas but maybe you can check the start relay (the one the ignition switch operates to power the starter solenoid) and also the inhibiter switch in the transmission...try starting in Neutral (I presume it's auto). Another trick on other cars is to press the 'unlock' button on your remote when you put the key in the ignition.
Here is a good explanation of surface charge: http://www.smartgauge.co.uk/surf_chg.html

Dammit! My TS v6 only has 90 amp output. Didn't know 3rd gen was more. 110A sounds so much better! Thanks for the info.

This may be out of left field, but on rare occasions a good battery has been known to go intermittently open circuit. There is no way to test for this, happens under load anyway. I kept a spare battery and tools in the car last time this happened to me. when it finally gave up permanently I swapped them over. Beats getting stuck somewhere.

why did you go so long with a known duff battery?

i had a customer once who had starting problems, it would not fault for us so he left the car with us while he went overseas... 1 month later after using the vehicle day in day out (and the day before the customer returned) it finally faults... open circuit battery
