Hi All,

As my CS is my weekend car finding havin go jump start - so is there any advice on how i can ensure i dont need to jump start after a few days not running?

I leave my ground cable snug not tight and twist it off after driving.Last for a long time for me.

either your battery is bad, or something in the car is using more juice than it should (parasitic drain). put a dc amp/voltmeter between battery neg and ground, you should have no more than 25MA - if you do, start popping fuses till you find the circuit, then go hunting from there. if less than 25MA, just need to replace your battery.

My battery can go for more than a couple months if needed without jumping.

Battery draining

When I first got my coupe the battery used to drain after a month or so. Then I found that the light in the rear trunk was staying on. Once I fixed the switch, no problems.

Same here, you must have a current draw or a bad battery.

I had a similar problem and discovered that I had a bad alternator. Replaced the alternator and that cured the problem.

I use an isolator to disconnect the circuit, also take the isolator key with me when I park it in certain places.
There is something special about the electric windows when you key off, apparently they work until you open a door once. Mine work with the key off occasionally, but not always. So I played with the door switches to see if that helped me understand the logic, still working on it!

Windows should always work once you open the driver side door.

The functioning of the driver´s door power window after the ignition key is removed, is something which I beleive the earlier cars did not have. An extra relay above the bonnet opening lever is associated with this function, I think... I may be wrong on both...
