Thanks for the diagrams. After making a diagram, checking, rechecking and triple checking continuity through all wires, pins, etc, I was sure the wiring was correct. Now I later noticed that the no. 3 pin on this 5 pin M12 search coil extension cable connector was originally grounded to the outer casing. The makers of this hipmount kit did this by connecting a thin wire to no. 3 pin and placed the opposite end between the cable and the clamp. This wire actually fell out when I separating the connector. Although I made a diagram years earlier, I didn't think it necessary to include this ground wire placement. I tried to determine which pin it was on. I couldn't tell. I replaced the existing cable, (which is the same type as e-series search coil cables) with one a little longer, The cable runs through a short square alum shaft, similar to an e-trac upper shaft but has a smaller I.D., being smaller than the M12 connector and the same applies to the female connector on the opposite end. So to replace the cable I had to first remove the M12 connector. After replacing the cable and connecting the connector, minus the ground wire, my e-trac was totally unstable, but only when using the hipmount. To the solution. Earlier when troubleshooting, I found that the no. 3 pin on my etrac coil cable connector was grounded, so when I connect my extension cable to my e-trac the no. 3 pin on the M12 at the other end was also grounded. This fact led me to assume that the before mentioned "grounding wire" was originally on the no. 3 pin, which proved to be correct. Now after this little fix my e-trac is good to go. Now I'm either going to attempt to repair my pro coil, ( right ear just broke) or buy better made coil, X-12 ?
Thanks Elmy, I may have to use your advice.
