What if your 1991 Jaguar XJ6 alternator will not start until it reaches 2000 rpm?

First of all you need to make sure you are working with a good Alt. With the engine off check Voltage at battery, start the engine then check the voltage. If it isn't showing any more volts than with engine off increase idle to 2 grand then check volts. Easiest and cheapest thing to do is replace Belt, tightening belt might cure problem but the fix is a new belt if not a problem with the Alt. You can have a good charging system but the gauge reading bad, the main thing is to have it charging. I'll just bet the Belt will cure your problem.

What is transmission stall of 2800 mean?
That means the torque converter will not start pulling until the engine reaches 2800 RPMS. Nother words transmission will not start pulling.
How do you tighten the alternator belt on a 94 jaguar xj6?
If its the 1994 XJ40 there are 2 nuts holding the tension on this system, the alternator is held in place by a threaded rod attached to the block (looking from the front its to the right of the alternator), loosen the nut on the open end of this rod and turn the inner nut until the required tension is reached and tighten the outer nut back up to secure it.
Does a tornado start from the ground or the sky?
No. A tornado starts in the clouds and extends towards the ground. Until it reaches the ground it is not a tornado but a funnel cloud.
What suppliesthe ae2100d3 fadec with power until engine rpm is sufficient for the alternator stator to take control?
The FADEC already has power prior to engine start. In fact it controls the entire start sequence. It receives power under normal starting conditions via an ECBU ; the acft will have power from either an external source, the APU, or an operating engine. The alternator stator provides power to the FADEC once the engine reaches 10% NG. This way the engine is entirely self sustaining once started and during the majority of start sequence. Should the alternator stators fail, power is then given from the ECBU again (28v DC power source).
When was the Jaguar XJ6 first produced?

What happens when an alternator does not work?
If the alternator has no output then the vehicle's electrical requirements must be supplied by the battery, until dead. In addition, if the alternator quits, the alternator light, located in the instrument cluster, will illuminate
