 Posted: Sat Nov 26, 2011 8:26 am Post subject: SD-8 installation |
 |
|
As I prepare to begin the installation of Z-13/8 on my airplane, a few questions arise.
Figure Z-25, the SD-8 with self excitation, shows a 12 AWG and a 14 AWG lead connected to a single male Fast-On terminal on the bridge rectifier. Is this done with a single terminal, or is there a suitable "piggyback" terminal available that would facilitate this? I have seen such terminals around, but they are not high quality AMP style terminals. Is there another way to terminate the leads onto a single tab and still be able to separate them if either the SD-8 or regulator should need to be removed?
Figure Z-25 shows the dynamo leads as a twisted pair, where as the other figures do not. Not at all difficult to do, but is it necessary?
If a connector is needed for the four leads from the SD-8 voltage regulator, is a Molex type connector suitable for use with the regulator on the engine side of the firewall?
Finally, the preliminary version R of Z-13/8 calls out an ATC style inline fuse instead of a fuselink at the battery contactor. Any further insight on this matter?

A yellow-PDGE terminal will accept both wires in
a single crimp.

no, but keep them together.

I'd rather see knife splices and heat shrink
in those leads than any sort of connector.

ATC30 in-line is fine and will be recommened in
the future.
