Okay, you need to put a voltmeter on the AC input wires to the regulator with the engine running (yellow) and see what voltage you get there at moderate RPMs (don't need to run up to full throttle . . . just see that here's a substantial voltage there - 20 volts or more). Do I presume correctly that you're wired per the latest verstion of Z-16? Is the relay closing (hear it 'click') when you move the master switch to full up position? You can do this while the engine is not running so you can listen. If the regulator is still the same version I looked at some years ago, it depends on a GOOD ground between regulator case and your firewall ground bolt.

What really bugged me wa s that the pictures of connectors were for ones that are NOT recommended. To be fair, this was pointed out in the caption, but how about showing peo ple what the good ones look like instead of leaving people guessing?

Yes. One side of the coil is connected internally to the contact that goes to the battery, and the other side of the coil is grounded by a switch on the panel. To put the diode across the coil, connect the cathode to the battery contact and the anode on the coil terminal. small sketch attached.

I looked on their website and they show it but I don't see an install manual available. EI recommends their own P-300C probes but since this was the gauge Van's recommended for use with the RV series capacitive senders (large flat plates mounted vertically on the ribs inside the tanks) I assume there was some collaboration to ensure things would work. I looked through the install manual I have and I'm afraid it doesn't say a whole lot. It shows the pre-wired connector and identifies red, black and white wires which go to each (right and left) sensor converter cable assembly but doesn't say what their functions are(I assume they are power, ground and signal). The factory bundled each of these sets of three wires with a "left" and "right" tag so you know which is which but, that's all the information they supply. Each sensor/converter cable assembly has five, individual, single conductor, unshielded wires that go into what looks to me to be a tiny circuit board about a half inch square that's covered with black heat-shrink. The three (red, black and white) wires connect to the gauge harness mentioned above and the other two wires connect to the senders in the tank (or the EI P-300 probe). I assume that if the wires from the tank to the converter cable CCA needed to be shielded then EI would have provided them that way. I think Van's just chose a BNC connection because it is very easy to drill a small hole in the fuel tank and pro-seal the connector in (no mess, no fuss, no leaking fuel, assuming the dielectric in the female BNC is resistant to attack from gasoline). And the BNC is a nice positive connection well protected from outside contamination. So... I just need to figure how mate one of the tank sensor wires to what would be the shield crimp on a BNC male connector. Thanks for the help.

I'm hesitant to connect my expensive panel with out it. Thanks, Sam Marlow ________________________________ Message 9 _____________________________________ Time: 11:30:51 PM PST US From: "Dennis Jones" Subject: RE: AeroElectric-List: BNC connector Bob I talked to B and C today. They did a test drive of the connectors and the same tool. He adjusted the crimping pressure however he still ended up with the flanges. He called them a slight flange. So I guess I need to find a different coupler that will fit with the tool. Any suggestions?
