They are a terminal removal tool for the BUSSMANN 15712-14-06-21A (Waytek 46074) The Waytek terminal P/N is 46074 for the Bussman blocks for which the removal tool is designed. I can send you a sketch. Very easy to make from a piece of ~.030-.040 thick steel. chris stone RV-8 Oregon -----Original Message----- From: rparigor@suffolk.lib.ny.us Sent: May 13, 2010 4:45 PM Subject: Re: AeroElectric-List: Bussmann fuse blocks Hi Chris "Be sue to get the terminal removal tool (it looks like a very small (10mm wide) two pronged fork)." I never saw a tool like that. Who sells them? Perhaps this: http://www.handsontools.com/Lisle-13120-Electrical-Connector-Separator_p_5706.html Thx.

ANY 1 uf tantalum (or aluminum for that matter) would be fine too. Radio Shack has a suitable part here: http://www.radioshack.com/product/index.jsp?productId 62392 If you're ordering OTHER things from Digikey too then this one would work. http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=399-3528-ND Did you check the output voltage when no tone is present? Also, it occurs to me that the output tone COULD be capacitively coupled . . . which means we'll need to add a diode to the circuit. But it will be a RS part too . . . so marching ahead with the current experiment is a good thing.

I'm not an aero electric expert, but I've been flying numerous aircraft for 35 years and I know what info I like to have displayed in the cockpit. I wanted current measurements. So, I inserted a HE device along the wire from the alternator to the #1 battery and a shunt on the wire from the #2 battery. My thinking was that I could monitor the amps going to the #1 battery to see how much load was on the alternator. It works great in that function and shows the high amps used to recharge the battery and then once it is recharged, it shows the load being used by the entire aircraft. The shunt will indicate the amps being drawn from the #2 battery should the alternator and #1 battery fail. I like having information in the cockpit. Control freak? Perhaps. Guess I've been a control freak for 35 years and didn't realize it. For me, just as I like to know what my fuel flow is, what my oil pressure is, what my system voltage is, - I also like to know my amperage load. Build it the way you like it. Stan Sutterfield So with your and Joe's clarifications about what the different placements of the current sensor mean, I will confidently sally forth to appease my inner demons. ________________________________ Message 9 _____________________________________ Time: 10:26:38 PM PST US Subject: AeroElectric-List: D-sub connectors, what is disadvantage of solder over crimp? From: "rparigoris" What is the disadvantage of using a 36 or 50 pin solder pot d-sub connectors (while having an extra set of hands to insert wires) where you heat shrink over solder pot and wire compared to using much more expensive machined pin connectors that are crimped?
