I have my 3300A physically installed in my CH601 HD using the JabiruUSA FWF kit.  I have a couple questions about the electrical system.  First, let me also tell you that I am an electrical novice, so I may be missing some rather basic information.  

            I have Revision 4 of the 3300A Installation Manual dated 22/08/03.  On page 10 is the electrical system.  It does not include a battery contactor.  Why is one not included?  Is there a problem if I decide to add one based on other builder's recommendations?  

            On the same diagram, the master switch controls only the battery.  There is no alternator master switch.  Looking at the figure on page 18, the single phase alternator is hooked up very differently than the old three phase alternator.  I have been told that Jabiru used to recommend an alternator master switch.  Does that only apply to the old three phase alternators?  Do I need one?  

            Thank you.

Hi Jeff,  

<![if !supportEmptyParas]> <![endif]>  

The alternator master is only needed with the old 3 phase. It was necessary to prevent the rectifier burning out when the engine had not been started but the master was on.

Jeff,

I use a battery contactor on my Zodiac 601XL/Jab3300A, activated by the 

master switch.  I also use a relay operated by an alternator switch to bring 

power from the alternator to the buss bar.  The "Master Switch"  is a split 

Cessna type (Master and Alternator switch).  If you close the Alt you 

automatically close the Master.  I procured the relay from Radio Shack.

 First, let me also tell you that I am an electrical novice, so I may be

            I have Revision 4 of the 3300A Installation Manual dated

 22/08/03.  On page 10 is the electrical system.  It does not include a

 battery contactor.  Why is one not included?  Is there a problem if I 

 decide

 to add one based on other builder's recommendations?



            On the same diagram, the master switch controls only the

 battery.  There is no alternator master switch.  Looking at the figure on

 page 18, the single phase alternator is hooked up very differently than 

 the

 old three phase alternator.  I have been told that Jabiru used to 

 recommend

 an alternator master switch.  Does that only apply to the old three phase

 alternators?  Do I need one?



            Thank you.
