Does anyone remember how to excite the generator when it goes off line, 
and will not come on after an engine start?  Its a lead from the 
positive side of battery to what terminal at the firewall???

thanks

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
