AU V8 starting issues

[david256]

My starting issues have been going on for weeks, but intermittently, originally I thought it was battery so replaced with an Optima Blue Top, then I thought was the Alternator not charging the battery fully over a trip the battery was running down. btw the Old Alternator was dropping down to 12.5-12.6 volts under load so it was almost knacked.

Thought everything was good for a week or so but now its returned.

When the car is cold it starts straight away 19/20 times, but if I do a short trip or turn the car off immediately the car won't restart all you hear is the starter relay clicking, which I swapped around just in case this was causing the issue. But if I do a longer trip the car starts almost every time until the car starts to cool then starts playing up until I've left it for a while.

I was thinking it was Smartlock as I would need to leave it for 30-90 minutes before it would restart, but I would assume the issue would be there all the time whether hot or cold, also doesn't effect if I give it a whack. Does anyone have an idea what the cost of a re-manufactured BEM costs from Repco or Bursons etc.

I'm now thinking its the starter or starter solenoid just not sure how temperature would effect either.

Any thoughts before I spend some more money.

Thanks in advance.
