Hello All,
After several months steep learning curve (still steep), I have come up with a design that meets my particular requirements. I have followed Bobs advice and gone for the Z13/8 type architecture. I have made some "minor" additions to give me an asymmetric split bus. To support dual electronic ignition, I need a backup battery and power supply and the attached design gives that with the minimum of fuss.
I am writing to the group to ask for some help with regards the following: - Dual electronic ignition is powered by either bus using bridge rectifiers. There are four ON/OFF ignition switches to allow for testing of each supply to each ignition system individually. Two (2-10)s won't do it. Is there a switch that does OFF-ON-ON-BOTH? This would allow me to reduce the four switches to two. Can anyone think of any other way to test each of the four ignition power circuits?
- Comments on the design. I am not looking for an endorsement, rather a critical eye on any mistakes or bad practise Can you point out anything that I may have missed?
- How do I cater for the charge current limited aux battery that I plan to install Do I need to anything special at all i.e. will the design do the job without additional modification? Attached is the spec. of a battery that I can source locally. Cycle use charging is limited to 2.88Amp and trickle use limited to 1.08Amp.
- Can anyone make any recommendations with regards an antenna and cabling for my GARMIN 496? I will be panel mounting it. Satellite weather is not available in Europe, and I am having difficulty sourcing an antenna that is not dual weather/GPS capable. The cost o f these antennas is prohibitive.
Thank you for your help.
