My firewall on the engine side is as per Z-20. The two options are either to monitor battery current (via the + cable) or Alternator output. If I monitor the battery then if the indication goes negative I'll know that my alternator has gone awol and I have limited battery power to get back on the ground (this is only a day/vfr machine). Would this be the best option as I can also keep a track on battery charging? What choice have any users of the EIS made on this sensor? As the Jab has a PM alternator, does this influence anything here? Many thanks in advance.

To save a little weight, of course, and for longer bulb life and to reduce my electron inventory. I've searched the archives, and have revisited all the sites mentioned here and in other lists in the past, but was curious about experiences that others have had with the brands mentioned. As well as any new manufacturers of LED navigation and strobe lights for my Long EZ similar to the physical configuration of the A600 series that haven't been mentioned yet. I'm currently leading toward Whelen's (an exact replacement for the A600, but a bit too pricey), and Skybrights ( www.airplanegear.com/skybright.htm ). Any other suggestions or comments are always welcome.

Leaving either one on could run down the battery. If you do shut those switches off, then check them with a voltmeter to be sure that they are opening up. 12VDC should be measured across the switch terminals when they are off (assuming an E-Bus load is turned on). Loads on the Main Battery Bus could also run down the battery. You could pull all of the fuses on that bus to see if the problem goes away. If you have a milliamp meter, disconnect a battery cable (negative is safer) and connect the milliamp meter in series between the battery and the battery cable. There should be zero current flowing with everything shut off. You need to be careful doing this. A large current could damage a milliamp meter or blow its fuse. If current is flowing, then loads could be disconnected one at a time until the current stops. That is the culprit. Your previous post dated June 23 mentioned pulling the Aux Alt circuit breaker. That eliminates the SD8 circuit as a problem. The Aux Alt Load Meter is another possibility. Disconnect the wires at the shunt to see if the problem goes away. Chances are the problem is something connected to the Main Battery Bus. What is connected to that bus in your plane? It seems that you would notice a dome light or a Hobbs meter running when it shouldn't. Have you double checked the ignition switch wiring and also the master switch wiring? How many days does it take to run the battery down?

I am using the Z13/8 with SD8 self excitation. I thought I had checked all the suspects and eliminated them one by one as the problem . So as a final step I figured the battery itself was bad. So I recharged a nd disconnected the ground from the firewall. Let it set and wouldn't ya kn ow it. It maintained a charge. So back to the drawing board. In checking al l the possible problems again I noted that that SD8 self excitation may be the problem. I have connected the ground back to the battery and the firewa ll. Will wait to see if it draws down again. With that said who is using the SD8 with self excitation as pre Z25. And if so any problems....... Being tech. challenged in this stuff I am not quite sure how to check the S D8 wiring to find the problem if in fact it is. If the battery discharges w ith the SD8 as configured then maybe it is the problem. I will recharge the battery and disconnect the SD8 from the battery contactor and see what hap pens. If the battery maintains charge with the SD8 removed I will know that the SD8 is the problem if not....................????????

If you're going to fuse the main bus feed, I'd say yours is right.

That lets me see what any particular item draws as I switch it on or off, and also how hard I'm working the alternator. There seems to be little value in monitoring battery current especially if you have a low voltage warning such as the one on your EIS. We know that the alternator is dead if the voltage is below about 12.5 volts. That said, I did have an occasion many years ago where a battery ammeter made it obvious that the battery was being cooked by a failed carbon pile voltage regulator. However the smell was probably the first indication noticed and these days overvoltage protection is available to us and that will act immediately resulting in - a low voltage warning. Your EIS also has overvoltage warning.

This seems to suggest a 2-3 style switch rather than the 2-10 style that I've installed. Is this 'important' note the latest 'best practice' (newer than Z11), or can I be confident with the 2-10 style (where the first position activates the battery contactor and the next position the alternator). Thanks.
