 |
|
I have a 3300A and am planning the electrical system for my Zodiac XL. I've looked at what others have done and absorbed much, but still have questions. I wish to keep things as simple as possible so hopefully you'll share your ideas with me.
Alternator / Regulator - I note that the Jabiru wiring diagram shows an unfused #10 to wire from battery to regulator (red wire) and an unfused #16 to the main bus (yellow wire.)
What I would like suggestions on is the best way to disconnect the alternator from the main bus in the event that I need to run soley on battery power due to a failure of some type. Would a switch on the yellow wire suffice or do I need to break the red wire as well? Any recommendations as to fusing?

Your best bet on electrical questions is to join aeroelectric-list(at)matronics.com . Bob is the man in the know and buy his book, it is the best money you will spend in the building process. Here is a link to his website http://www.aeroelectric.com/. He has diagrams that address all of your questions and more.

Tim, you will need to disconnect both wires if you want to isolate the regulator due to some fault, simply because you wont know which wire is carrying / causing the fault. The yellow wire should be bonded to the red wire at the regulator, and the extended lead can go via a fuse, fuse link or cct breaker to the batt +ve. This is the safest option and the recommended wiring method as written in the current Jabiru installation manual. I think Bob's Z20? is the most recent diagram -equally safe and with more protective measures and features.
