I just downloaded a copy of the current version from: http://www.aeroelectric.com/R12A/AppZ_12A4.pdf It's a big file . . . it may take a few minutes for it to pop up after you call for the download.

What do I need to supply that protection. I have >and reviewed your cd. Unlike generators that had over current or over load protection built into their regulators, alternators are inherently self-limited to the amount of output current. They are incapable of destroying themselves due to drains that exceed nameplate ratings. This assumes of course that they are adequately cooled. In other words, if the alternator is installed and fitted with conditions that allow continuous operation at full rated output, then having them operate in current limited mode (10-15% above nameplate) does not represent a hazardous condition. Alternator b-lead conductors in airplanes have traditionally been protected by either a fat breaker on the panel or (in the case of Z-figures) some form of robust fusing on the firewall. This "fuse" is depicted as an ANL style device usually located right next to the starter contactor. //// (o o) ===========o00o=(_)=o00o======== < Go ahead, make my day . . . > < show me where I'm wrong. > ================================ ________________________________ Message 5 _____________________________________ Time: 04:35:53 PM PST US From: Tom Packard Subject: AeroElectric-List: Starter and contactor wiring Bob and/or others with help.. A couple of months ago there was some discussion about wiring a Skytec starter per Vans recommendations. I believe Bob recommended eliminating the jumper wire between the Starter B+ and 'S' terminal and connecting the 'S' terminal to the starter contactor "I" terminal. I am installing a Skytec 149-NL starter and the instructions say to remove this jumper wire when wiring for 24 volts and leave it in for 12 v operation. Does removing the jumper effect 12 volt operation? Also, I would like to add a 'starter engaged' warning light per Bobs' recommendation in the "connection" by wiring the "I" terminal of the starter contactor thru a 5amp fuse to the warning light. Any problem with doing both wiring alterations?
