Hoo-boy....
Thanks Bob and others for recommending Z13/8....happy to continue with your dwgs and single battery..... till I read about the Lightspeed manual stating at paragraph .2.7..
Electrical System Requirements
All Plasma CDI systems can be used with 12 or 24 volt electrical systems. Input voltages above 35 volts or reversed polarity will cause system damage.<?XML:NAMESPACE PREFIX = O />
For this reason it is mandatory that all aircraft using Plasma CD Ignitions are equipped with over-voltage protection in their alternator charging system(s). Over-voltage is a requirement for certified aircraft. Power connection must be directly to the battery terminals to avoid voltage spikes and electrical noise. Aluminum should never be used as an electrical conductor for the Plasma CDI. Use only the supplied aircraft quality stranded wire.
Electrical Operating Instructions
Dual Systems only: If you have installed an aux battery per the LSE supplied drawing, monitor your voltmeter and do not switch to the aux battery until the supply voltage of the main battery is below 6.5 Volts or the engine is not running smoothly. After switching to the aux battery, your voltmeter will read the voltage remaining in your aux battery.
Do not switch your main alternator breaker in flight to avoid potentially damaging voltage spikes. This does not apply to the alternator field breaker.
And further at para.2.8A....
A. Power Supply -
· When connecting the power supply, route the positive lead to a pull-able breaker, 4-cyl systems use 5A ...., and then directly to the battery plus terminal, bypassing any electrical buss or master solenoid. Refer to the Input Connector Diagram & the Electrical Requirements section 2.7.
See here..... http://www.lightspeedengineering.com/Manuals/CdiManual_PlasmaII_II+_III.htm
And then for Dual Plasma CDI, Klaus further recommends.....
For Dual PLASMA CDI Installations, an auxiliary battery and dual ignition indicator lights are recommended. Please click here for an aux battery wiring diagram.
See Figure 4 for the dual ignition indicator lights diagram: click here.
See here for the AUX Batt Diagram..........http://www.lightspeedengineering.com/Manuals/PS_Diagram.htm
How do I incorporate these- the 2 x "pullable" C/bs and 2 x batteries - within Z13/8...?
Thanks,
Robert
