Dear Listers, Some have asked, "What's my Contribution used for?" and that's a good question. Here are just a few examples of what your direct List support enables. It provides for the very expensive, commercial-grade Internet connection used on the List insuring maximum performance and minimal contention when accessing List services. It pays for the regular system hardware and software upgrades enabling the highest performance possible for services such as the Archive Search Engine, List Browser, and Forums. It pays for narly 30 years (yeah, I really said *30* years) worth of online archive data available for instant random search and access. And, it offsets the many hours spent writing, developing, and maintaining the custom applications that power this List Service such as the List Browse, Search Engine, Forums, and Wiki. But most importantly, your List Contribution enables a forum where you and your peers can communicate freely in an environment that is free from moderation, censorship, advertising, commercialism, SPAM, and computer viruses. How many places on the Internet can you make all those statements these days? It is YOUR CONTRIBUTION that directly enables these many aspects of these valuable List services. Please support it today with your List Contribution. Its one of the best investments you can make in your Sport...

That video is a great find. Thanks. --Rick On 11/27/2018 10:21 AM, Robert L.

At cruise I've been seeing between 14.5 and 14.7 volts on both buses. I've been running like that for over a year. On my last flight I noticed the voltage on bus 2 dropped almost 1 volt. It was jumping around between 13.4 and 14.0 volts. I removed various loads to see if perhaps I had a malfunctioning component but this had no effect. I engaged the cross feed to connect the 2 buses. Bus 2 remained at 14 volts or less but was less jumpy staying closer to 14. Bus 1 remained at 14.5 to 14.7. With the cross feed engaged and Bus 2 switched off, the voltage on Bus 2 dropped to between 12.4 and 13.7 With the cross feed engaged, I pulled the CB on the bus 2 regulator taking the #2 regulator/alternator offline. Bus 2 voltage was between 12.8 and 13.5 (bus 1 was 14.5) I don't have a load tester but the bus 2 battery seems okay (12.78volts with no load at 50F). It would seem that I'm getting some current from the alternator but there has been a distinct drop in bus 2 voltage. I would have thought that both buses would have roughly the same voltage when interconnected with the bus 2 alternator offline. I'm looking for some advice on troubleshooting.

My Z14 does show both voltages the same with the crossfeed closed as you surmise. I'd want to verify that the buss 2 voltage is accurate with a separate meter. Next I'd physically disconnect the buss 2 alternator to see what happens. Or measure the current from (or into) the #2 regulator or alternator if you have a current meter. A DC Clamp ON ammeter is handy for rough DC current measurements. (under $20. on ebay).
