You're right it is Hitachi. Would you please send me the web site where you found this info, or where I could get additional technical data on the regulator, a schematic, etc. Bill ________________________________ Message 2 _____________________________________ Time: 07:06:22 AM PST US From: WRBYARS@aol.com Subject: Re: AeroElectric-List: (no subject) --> AeroElectric-List message posted by: WRBYARS@aol.com Bob, my previous post left out this info: Hitachi, LT150-62 alternator.

I did build and install his marker beacon receiver in my RV-4 and was pleased with its performance. Jim seems to know what he is doing. YMMV.

B&C > cannot supply. John Murphy If you use breakers, go with the screws. You need to connect all the breakers together with a common bus bar which will screw directly onto the breaker terminals. One of the goals for using fuse blocks is to reduce the system parts count. If you use fast-on breakers, then the parts reduction gained with fast-ons at the breakers is lost when you have to fabricate a bus bar, support it, insulate it and install a jumper wire from the bus to the breaker with more screws and two terminals, only one of which is a fast-on.

I'm trying to figure out how to wire this. The LASAR enunciator light socket has three inputs: (1) positive voltage from the bus, (2) negative feed, and a third (3) feed which comes from the LASAR ignition black box. I want to wire this to a light socket which has only two posts. I've tried using just 1 and 3 and the light just stays on. Didn't want to experiment much further. Any ideas? -- Walter Tondu http://www.rv7-a.com ________________________________ Message 6 _____________________________________ Time: 10:29:27 PM PST US From: "Kingsley Hurst" Subject: AeroElectric-List: Vinyl Insulated Ring Tongue Terminals --> AeroElectric-List message posted by: "Kingsley Hurst" Bob et al, When I went to order some Vinyl Insulated Ring Tongue Terminals on the weekend, I noted in the ACS catalogue that for example, 22-16 (Red) terminals have stud sizes of 4,6,8,10, 1/4 Could you enlighten me as to what this seemingly convoluted way of sizing the holes means please ? Eg If I want a terminal for a 3/16" stud, what is the correct number equivalent ? Thank you in anticipation.

You mentioned that with these smaller switches I would need to use a relay for pitot heat, nav and landing lights, and other high current needs. I reread your chapter on switch ratings, and reread the spec sheet for the NKK 2100 series switches. They are rated for resistive loads only: 3 amps at 30 volts DC, 6 amps at 125 volts AC. With a life cycle of 25,000 electrical and 50,000 mechanical, I don't mind overloading them. But the chapter on incandescent loads is worrisome. I may need to use some of the ugly automobile switches rated for 20 to 30 amps. Radio Shack, Pep Boys, Kragen Auto all have rocker type lighted switches with a round hole mount and 1/4 inch tabs. These use a large bar of copper internally to make contact. I took one apart last year, but can't do the nice photomicrographs that you do to show this. In any event, rather than use relays, I will use a switch with higher ratings for incandescent loads. Listers should know that there are a wide variety of high current switches with LED or illuminated actuators and 1/4 inch tabs. The highest quality unit, made by Cole-Hersee, is about $19 from West Marine, and is slightly larger than a standard toggle but with a plastic case. It is sealed, rated at 30 amps, and has a white LED tip. At the other end of the toggle spectrum, for about $4.00, is a #85909 Conduct-Tite switch from Kragen, also rated at 30 amps. It has a plastic toggle wrapped with an aluminum tube with a red LED at the tip. Looks nice, but I will carry spares. Fortunately, the landing lights are HID from Hella. I don't think the HID ballast will pull the same current spike as a cold filament, so I can use the nice NKK switch. I wonder if it is possible to estimate the risk of a welded switch by the rise in resistance after a small numbers of cycles, say, 100. Perhaps this is another application for the milliohmmeter...

The 2nd post is just used as a push to test, that is the reason you have three, but as the ignition is on fault when you switch it on and do the magneto check, you do not need this functionality. You did wire it correctly, as the enunciator will go out, when the engine is running after about 20 seconds only =(;o). Just in case you have once problems starting after the first splutters, try to "reset" the Lasar by switch off power for a few seconds, then engage again and it will start immediately.
