Posted: Wed Dec 06, 2006 6:49 pm Post subject: Jabiru Starter contactor and solenoid

I have a Jabiru 3300 and have a 702-1 starter  contactor from B&C.  Looking at Z-20, from aeroelectric, they are  running the 4 AWG wire to the starter solenoid.   It looks like  the "solenoid" supplied by Jabiru is really just another contactor.   It is wired and works the same as the 702-1 but with out the diode.   If I  hook it up as depicted in Z-20 all I will be doing is to energize the coil on  the Jabiru supplied solenoid with the 4 AWG wire from the 702-1.  It sure  looks to me that all I will be doing is putting two contactors in series.   I am not sure of the value in this.  I am considering just leaving off the  Jabiru solenoid and connecting the 702-1 directly to the starter.   

  

 Is this smart or is there something I am  missing?

  

 Thanks

I have a Jabiru 3300 and have a 702-1 starter contactor from B&C.  Looking 

at Z-20, from aeroelectric, they are running the 4 AWG wire to the starter 

solenoid.   It looks like the "solenoid" supplied by Jabiru is really just 

another contactor.  It is wired and works the same as the 702-1 but with 

out the diode.   If I hook it up as depicted in Z-20 all I will be doing is 

to energize the coil on the Jabiru supplied solenoid with the 4 AWG wire 

from the 702-1.  It sure looks to me that all I will be doing is putting 

two contactors in series.  I am not sure of the value in this.  I am 

considering just leaving off the Jabiru solenoid and connecting the 702-1 

directly to the starter.



Is this smart or is there something I am missing?

    First, the Z-figures are ARCHITECTURE drawings and not intended

    to dictate wire sizes, breaker/fuse sizes, or equipment choices.

    They are simply foundations upon which your own system details

    are laid.



    The apparent "dual starter contactors" anomaly you've cited

    is discussed in the article at:



http://aeroelectric.com/articles/strtctr.pdf



    Depending on what features are specific to the starter supplied

    with your Jabiru, the specifics illustrated in Z-20 may not

    apply.



    If your existing starter is fitted with the hi-inrush, pinion

    engagement mechanism typical of B&C starters, then the "dual

    contactor" philosophy -or- the Starter Boost relay shown

    in Z-22 is recommended to enhance the service life of your

    starter push button or switch.
