can someone tell me if the nissan alternator on my 2000 gu 4.2 td charges at idle. i have a volt gauge that drops its display at idle, but as soon as the revs increase its ok.
hoping to hook up a relay up to the alternator, and don't want it to turn on at idle. to put it another way i want it to drop out at idle.
cheers shane.

The alternator will charge at idle.

What are you trying to achieve ?

There are other ways to control circuits.

Regards

Derek.

Sounds scary.

Perhaps use a micro switch on the throttle.

thanks, did you get the problem sorted with the tyre monitor not picking up the far side of the trailer/caravan that Roachie was on about a few months ago? i am interested in this system for my van but am concerned about this.

Yes, used a metal valve extender.

thanks Derek, is this the bent one that trucks use?
can the monitor be left hooked up to power, as in cig cable?
thanks shane.

If the voltage drops below 13.6 volts at idle then the Alternator is not charging.

My Pajero 3.2 Diesel can put out 25 amps at idle.
