Two steps to success when wiring up a coil on the Excalibur.

[Mel Parker]

Many of us have attempted to change coils on the Excalibur and forgot which way to hook the wires back up after we cut the coil cable or when we are using coils from a different manufacturer that has different color wires.
Here is a simple way to get the phasing right on both the transmit and receive wires. The transmit wires will have the lower resistance or if your using a Minelab coil the colors are usually red and black. The receive wires have the higher resistance and the wire colors on these can vary.

1) Hook up the transmit and receive wires to the Excal. Transmit to transmit and receive to receive. Put it in the all metal/pinpoint mode and turn the unit on. If you don’t get a threshold tone reverse the receive wires and power the unit back up, you should have a threshold tone.

2) With the unit powered up in the all metal/ pinpoint mode pass an iron object over the center of the coil, if it nulls or goes quiet the transmit wires are reversed. Power the Excal down and reverse the transmit wires.

3) You should be good to go at this point. I never use the confusing hook up charts that are on the internet because sometimes you don’t know what has been done to the Excal or the coil.

I came across several SEFs last year that were wired up wrong and if you ran anything metal, with the machine in PP, across the center, it would go beep before it hit the center, then null as it passed the center then beep again. (inverted signal) I checked the chart that was out and all was wired to the chart but the chart was wrong...black n gray were reversed, once swapped all was back to normal. But amazing the coils were wired by XXXX and the hunters continued to use and never noticed. In Disc it is harder to notice....so I guess they hunted in disc all the time. I did bring it to the attention of and was told the company had wired the coils wrong....? And was asked not to say anything.

I was good until you said there were 4 wires. Interesting they didnt notice it wasnt right. So how did it end up at your door step Joe? I bet their finds increased.

I have a question.
On my Excal 1000,
If you are simply installing a Toranado coil in place of the stock 10" coil.
lf I match the black to black,red to red ,white to white and yellow to yellow.
Is this correct?
Thanks.

Yes,
and put here a waterproof connector http://www.ebay.com/itm/252054708317

Anyone have a good understanding of the wiring options in the pc board itself?
I'd like to understand the rx/tx/ground options on the board - which is different than just trying things until they "work".
Why are there these options - done for compatibility with old model coils? Even so I don't undesrand what would be different for them.

Hi
There are several options for connecting to the board (depending on the version )
So I drew pinouts for excal & sovereign

look ip-68 connectors http://www.ebay.com/itm/252054708317

I have a few coils that have 5 wires not 4 and the color of the wiring is different as I have black red green orange and blue but dont know how to hook up as I am used to the norm of black red yellow and white please help Thanks

I think the older BBS coils had 5 wires instead of four. Years ago I purchased a lot of BBS coils and noticed some had an extra wire not needed when I added the 6 pin mic connectors. Some of these coils had cable rot, but the five wire coils didn't suffer from this problem. Pin 3 and Pin 6 are fused together in the box, which 6 isn't needed if a meter isn't used. HH Ron

I think there were two that ohm’d out as grounds (zero ohms) while the other wires were identifiable by like 1.5 ohms pair and 1.5K pair. Identify ground and tie the spare wire to it and it should work. My small coil was done this way and works on a 4 wire sword and excal2. I have plug interconnects for both so I can switch them around. Got the NEL Attack working for both too. Your black/red likely the tx. Tie the spare wire to whatever is ground, probably black?

Oops, told you wrong. See photo. Green and blue tied together to pin 3. Black pin 4. Red pin 1. Orange pin 2.
