In my case how "fancy" should I go? For connections to the load from the battery, I was thinking of simply using two leads of #10 wire with alligator clips on both ends and having an inline fuseholder on one lead with a 15A fuse. Or...do I fabricate a switched/fused platform, with ring terminals for connections, etc? User preference?

Nuckolls, III" Subject: AeroElectric-List: Rainy day project Been trying to wrap up a fuel tank/pump/sender replacement on the ol' pick-em-up-truck . . . too cold and wet for these ol' bones to lay under the beast on a creeper! The truck has been up on jacks for about 10 days and I'm down to a couple hours work to finish . . . but not to let a rainy day go to waste. I mentioned a goal to formalize some demonstrations and data gathering on fusible link materials. Been pondering ways to generate 100 to 800A test currents. Settled on this approach this morning: Configure the link-under-test with a switched dead-short across it using a contactor. Wire the test article to a fat battery, (I've got a couple 100ah tractor batteries on hand at the moment) and a battery load tester. The test starts with the contactor closed. Then crank up the battery tester load to the desired test current then open the contactor. The 'test' indicator lamp will be visible in a video that records response of the fusible link. Depending on weather, I might get a chance to shoot some video yet this week. It's been awhile since I deliberately let the smoke out of stuff . . . this should be fun.

You're not switching a really big current . . . yeah, there will be some 'sparking' when you clip the final joint closed but they don't call us electron-herders 'sparkies' for nothing. 20 AWG wire would be fine . . . the leads are short and the anticipated 13A load is easily managed by that size wire. Same with alligator clips. KISS my friend . . .

Bob . . . ________________________________ Message 8 _____________________________________ Time: 04:37:29 PM PST US Subject: AeroElectric-List: Re: John Deere VR From: "user9253" Can you post a picture of your John Deere regulator? If it looks like this one, B+ terminal goes to a 30 amp fuse that is connected to the downstream side of battery contactor. The AC terminals connect to Rotax permanent magnet generator (yellow wires) L is for a lamp. Usually not used. IGW connects to a switch (labeled "Alternator") which gets 12 volts from a 3 amp fuse on the main power bus. Be sure to mount regulator using heat conductive grease between aluminum surfaces. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=496327#496327 Attachments: http://forums.matronics.com//files/john_deere_regulator_159.jpg ________________________________ Message 9 _____________________________________ Time: 04:53:55 PM PST US From: William Daniell Subject: Re: AeroElectric-List: John Deere VR I originally bought this as a back up to carry in my flying tool/spares pack.
