docc Posted November 15, 2016 Author Share Posted November 15, 2016 What are the 3 bare terminals Docc? Your VII looks totally different under the seat than mine. HRN and the silver thingame? Sent from my shoe phone! The terminals are part of a junction block to get the terminal stack off the battery. I added one on the negative side as well. The only terminals I left on the battery are the main cable to the starter, the charging wire (subject of this thread), and the feed to the junction block. "HRN" is the ATC fuse holder for the direct hot to the two separate relays for the FIAMM horns which ground back to the frame bracket that mounts the Fuel Pump. The "silver thingey" is a 10 amp auto-reset circuit breaker for the hot to the headlamps which are switched by a pair of separate relays in the headlamp bucket. They, too, ground back to the frame. (Photo shows the first attempt at relocating the Regulator Fuse). 1 Link to comment Share on other sites More sharing options...
docc Posted November 15, 2016 Author Share Posted November 15, 2016 For what it's worth.. the FAA doesn't allow soldered terminals. The solder wicks up the wire and makes it brittle. It'll eventually break right at the terminal with vibration. Just the same.. I don't blame you for doing that. I'd be upset, too.. Thanks, Chuck. Good to know. I didn't even add a terminal end in order to minimize the number of connections. Perhaps this latest approach will hold for a good long time. Alternate Method E !

Kiwi_Roy Posted November 16, 2016 Share Posted November 16, 2016 We have to get FAA approved now Nice soldering. I know what Chuck means, when I used to work on railway signals you weren't allowed to use any sort of a lug. Link to comment Share on other sites More sharing options...

What gets used for wire connections in airplanes? Presumably the very best possible, most reliable connection? Can we use them here? Link to comment Share on other sites More sharing options...

It's just a crimped connection with an aircraft crimper.. and.. aircraft terminals. Let me dig through my pictures, and I'll be back. Maybe in the morning.. 1 Link to comment Share on other sites More sharing options...
Chuck Posted November 16, 2016 Share Posted November 16, 2016 A guy likes to think he's doing a good job, then he finds out he shouldn't be working on airplanes! Ya know.. Docc.. that looks nice. Good job. It'll be a while before it breaks. *Maybe* a long while. Link to comment Share on other sites More sharing options...
docc Posted November 16, 2016 Author Share Posted November 16, 2016 Gentleman, I want to thank you all for all of your insight, education, and encouragement. Let's face it, what I'm posting isn't "rated" for anything. *Entertainment Value Only* *Don't Try This At Home* The last time I thought I "fixed" this problem, it took like eight years to fail. So, let me get back to you in about 2025 with an update. Seriously? Do not neglect your #3 / 30 amp, "regulator" fuse. They are are known to overheat. 3 Link to comment Share on other sites More sharing options...

docc Posted November 16, 2016 Author Share Posted November 16, 2016 Thanks, Chuck! Looking to start it up in a couple hours. Guess I oughta have that fire extinguisher handy . . . Link to comment Share on other sites More sharing options...
docc Posted November 16, 2016 Author Share Posted November 16, 2016 Soooo . . . . turns out you don;t need a fire extinguisher if there is no power to back half of the fuse block. Seems, from the wiring diagram, that power to fuses 4 and 5 must trunk off of the battery wire to Fuse 3 which I replaced with a dedicated, separate wire outside the loom. Looks like I need to fish that terminal out from where it's stowed and reconnect it. Good thing I didn't clip it off at the loom . . . EDIT: Yes, that restored power to the Ignition Switch. And I still have 14.2 volts charging. Link to comment Share on other sites More sharing options...

I'm not sure I answered this very well. The HRN (horn) fuse and silver (headlight) circuit breaker get dedicated hot feeds from the terminal block. It does not stay "bare," but has a cover. Also visible is the rubber guard over the corner of the ECU which covers its ground and is vulnerably close to the positive battery terminal. The terminal block holds the hot feeds for the horns, headlights, GPS, SAE accessory plug, power to Fuses 4 & 5, and a clamping point (capped in red) for direct charging or voltage readings since the positive battery terminal itself is not very accessible. Beyond the wiring, but still electrical: labels for the row of OMRON High Current relays, relocated signal flasher, detailed fuse function chart (inverted for roadside viewing), and [CarlAllison] wiring diagram in the tool tray. 4 Link to comment Share on other sites More sharing options...
Kiwi_Roy Posted November 19, 2016 Share Posted November 19, 2016 That's neat, I have been meaning to do that to mine, I think I have up to 5 wires on the battery terminals. I also like your re-located flasher. 1 Link to comment Share on other sites More sharing options...
sp838 Posted November 21, 2016 Share Posted November 21, 2016 Love the idea of a circuit breaker instead of a fuse. Link to comment Share on other sites More sharing options...
