 |

A question for users of the Jab3300: have you been able to wire the alternator regulator into one of the Z- schematics by Bob Knukolls? How do you shut off the alternator? As you probably know, the wiring diagrams in the Jab manual, pages 54 and 65, are inconsistent. Any of you sorted this out?
Comments wil be greatly appreciated.

should check wiring for a split switch. Alt/ Mag switch.

Take a look at diagram Z-20 here:
http://www.aeroelectric.com/articles/Rev11/AppZ_R11J.pdf
The title is "Small Jabiru System".
Bottom line is that a permanent magnet alternator like the Jabiru has can't
be shut down. It has no field winding creating the magnetic field, just a
number of permanent magnets. So the best you can do is disconnect it from
the rest of the system. That is what the over-voltage relay does in the
design linked above.

More controllable than an automatic overvoltage shutdown would be the use of a continuous duty relay. It can be located between the alternator , thereby output and the battery avoiding a long run of heavy gauge wire. The long run of wire back into the cockpit from the relay is small gauge wire to the switch.

The advantage of an automatic over-voltage shutdown is that it will fire in
less than a second, possibly preventing a fire and saving some very
expensive electronics or your battery.

I modified Z-16 for use with my Jab 3300. I have is available on my
website. I converted it to Delta cad and have it there in both deltacad and
PDF.
