URGENT! WATER AS FUEL DISCOVERY FOR EVERYONE TO SHARE

Been watching from the sidelines but felt the need to jump in and ask some questions regarding Bill's Nexus circuit.

1. If the output from the MOT is connected to engine ground, and engine ground is connected to the minus terminal of the battery - are they not the same electrical potential? Why does bill say to connect the capacitor to minus battery terminal and NOT the output of the MOT. It seems to me that the circuit would work either way. What am I missing here?

2. The inverter is marked NEU and HOT on the output. Since the output is an AC voltage how do the terms NEU and HOT apply?

My cousin and I created the nexus circuit and tried it on one plug removed from my 1996 Geo Metro  - just as Bill demonstrated in his video. With the engine running and the 400 watt inverter turned off there was no spark at the plug. When I removed the DC connection (60 1N5408's) then the HV spark showed up. That should have been my first clue. I connected the 120V DC back to the plug and turned the Inverter on.....Instant smoke! I am now a member of the fried inverter club

I will try the simple dual LED trick posted earlier to determine whether I have a negative or positive HV spike and connect the diodes accordingly. I believe this is a crucial step in getting the Nexus circuit to work - and to keep from frying inverters!

Be sure that your inverter is (insulated) not grounded to the body or it could short circuit.

@happyvalley808,

I have tried capacitive pickup for ignition coil cable driving the led in a opto coupler so I know
the method will work but I have not tried the simple led tester yet.

There is a easy way to test this, see post above.

@bwb,

I fully agree. Be careful with high voltage.

Another issue is water and humidity. Ready bought inverters (most of them) uses a fan for cooling.

If you mount the inverter in the engine compartment then your in trouble. One engine wash
and you inverter is ruined. If you put the inverter into a plastic box (fully closed) then your
also in trouble, no air flow for the fan cooling.

The main reason for building my own inverter:

The output voltage can be designed to suit my voltage needs.
The inverter uses no fan and can be water resistant.
The inverter is fully insulated by the use of a output transformer.

Attached is my newest inverter version. Still testing the inverter but it is beginning to work OK now.

Yes, the inverter as well as all of the additional components were mounted on a piece of 3/4" plywood which worked very well. I just had the HV diode protection string wired backwards. Next try will be a winner!

Hello, I don't think I've posted here before, mostly on energetic forum. When I got to the point of testing the Nexus circuit for correct operation yesterday, I flipped on the inverter with the engine running, and It FRIED!! Just as yours did. So, I figured diodes were in the wrong direction. Changed them to face oposite direction, flipped on the NEW inverter, and FRIED it too!!! I have tried all kinds of configurations to get this circuit to work, so far, NO LUCK! I even tried the way Wilber said he got it to work, with a full wave bridge instead of half wave. Red light instantly came on for inverter, I shut it off quick enough to keep it from frying.........that time. I agree with you about the "Neutral" and "Hot" outputs from the inverter. Whichever lead you put the half-wave rectifier into, becomes readable as DC neg between the two leads with a meter. Then you're supposed to hook the +pos lead from there to the engine block? On the original schematic posted by Mr. Bill, the diode array direction lets the HV+ from the spark plug end feed straight through the diodes back to the inverter. I had a digital meter on the table close to the inverter, not hooked to anything, and it was going nuts with the engine running and inverter off. On one occassion, just running the engine lit up the green "power" LED on the inverter.......the inverter was NOT turned on! Even if he used reverse-bias diodes and I used forward-bias, changing the direction would fix the problem.........and it hasn't thus far. I now have a total of 6 inverters under my belt, but only 2 are from this circuit, the cost of inverters is starting to add up! If we can figure out the problem SOON, it would be wonderful to use this "simple piggy-back" system. If not, I'm just going to build the "gmeast circuit", I like it very well just a little more complicated to hook up to a V-8.

BTW, has anyone heard ANYTHING further from Mr. Bill regarding how to actually make this circuit work?

@everyone

Keep up all the good work and testing. We will get there eventually!!!
