HI Bob,

 �

 This has happened to me where the generator wouldn't come online after  having the tail off.

 �

 You will need a long set of jumper cables or a very heavy gauge wire and  then:

 1. Hook ONE lead to the Positive side of the battery and run it back to the  voltage regulator box (silver box) at the�fire wall.� This is the  silver box that has the single "finger screw" in the center of it.�Loosen  the finger screw and remove the cover and you will see 4 leads.

 Two leads coming in from the right side of the box and 2 leads coming in  from the left side of the box while looking at it from behind the firewall while  looking forward towards the nose of the airplane.

 �

 2. Find the POSITIVE lead on the LEFT side of the voltage regulator box  which will be the TOP lead and they are labeled + and -� .

 �

 3. Take your jumper lead and make�MOMENTARY contact with the POSITIVE  lead on the LEFT side of the voltage regulator box (It should be the lead on the  top).� Wear protective glasses and gloves!� It will Spark rather  impressively.

 �

 4. Try to start the engine and see if the generator will come online.�  If it doesn't shut down the engine and as the engine spools down,  make�MOMENTARY contact with the POSITIVE lead on the LEFT side of the  voltage regulator box again.� With the engine spinning� the generator  will be turning and you will get it this time.� Sometimes it's in the wrong  position and with the engine still spinning it will take care of that  possibility.

 �

 5. Problem solved and system now again "flashed" and generator should come  online IF that was the issue.

 �

 It usually is the reason that the generator won't come on line and is an  easy fix once the tail is off of the plane.� A lot of guys think they have  a bad generator or voltage regulator and end up replacing them both when there  is nothing wrong with them.

 �

 Have fun,

 �

 Scott
