To Bob Nuckols

  

    I have a Velocity with a Z-14 wire configuration. I have duel  light speed electronic ignitions wired directly to the two respective  batteries . In the event of a dead battery how do you get the dead battery  contactor closed with the other system so you can charge the dead battery which  keeps its respective electric ignition going.   I know there  is a solution because you gave it to me a few years ago and I was able  to do the following .     Recently I had a dead  auxillary battery due to leaving on the pitot heat.   I started the  engine with main battery and was able to close the auxillary contactor with  power from the main system.  I believe this was from a modification you had  suggested to me when I wired the system. I can't remember what the modification  was.  Could you repeat it for me?    I love this system  because I was facing a long X-country flight and I was able to still go due to  still having one good battery and two alternators.  Love the  redundancy!!!  Fantastic!!!

  

 Thanks Tim

   I'm pleased that the design goals for this system

   proved useful to you. The data you're asking about

   is Figure Z-33 which you can download at:

Bob thanks for the Z-33 that shows duel power to contactors. This has lead  to another question. I have S701-1 contactors as shown in Z-14. Can these be  wired for duel power sources or due I need to replace them with S701-2 type  contactors.   Thanks Tim

   The only difference between a 701-1 and 701-2 is how the diodes

   are installed. You can remove the jumper wire on a -1 and add

   two diodes to convert it to a -2. The only time you would need to

   replace the contactor is if you had purchased a 3-terminal device

   common to other suppliers of battery contactors.
