I replaced the ACS ignition switch and have not had a problem since. I opened up the original switch and could not see anything wrong with it. They are very simple devices. -------- Dennis Read this topic online here: http://forums.matronics.com/viewtopic.php?p=370617#370617 ________________________________ Message 2 _____________________________________ Time: 12:09:03 PM PST US Subject: JabiruEngine-List: Capacitor Installation for Ignition Noise From: "dwwilt" I made a search of the forum and could not find this, so I am asking the group. I have ignition noise in my radios. I have the Jabiru 3300 in an Arion Lightning. My radio stack has a PS-Engineering PMA5000EX with a SL-30 and SL-40. I know where to install the capacitor on a standard type alternator, but the built in alternator for the Jabiru makes it kind of hard to decide where to put it. Has anyone had this issue and solved it with the capacitor? And if you did, how did you install it?

If the noise is from the alternator or regulator then maybe it might help. It sounds somewhat like you are trying to slice an orange by cutting into a watermelon. (forgive my awkward attempt at humorous analogy).

Is it a low value such as 0.2 uF? Or a high one such as 25,000 uF (or greater)? The small value goes right next to the OUTPUT of the alternator. Keep the leads SHORT. The High value - Well, there you have some options. You can put it right at the B+ Buss to Ground. That way it removes the noise and filters all of the electrical system. OR, you can also put it right at the alternator - The SAME as the low value capacitor. But there it will not do as much to remove noise entering the radios. The BEST of both worlds is to use BOTH value capacitors... Small value at the alternator and the larger at the B+ Buss. AND... One more trick... Install a ferrite (snap on) bead on the alternator wire as close to the battery as possible. The bead must be a TIGHT fit over the alternator output wire. Question: What type and where is the ACU (Alternator Control Unit) located?
