Hi All:

So here is the problem. My Datamarine Corinthin II depth sounder died, in that it was giving eratic and inaccurate readings. I sent it to DMI who said the unit was OK and that the problem was likely in the transducer. As the unit is no longer made (company out of business), I was able to find a new transducer from a company that had a lot of Datamarine parts for sale. I installed it but ran the wire along the cabiin sole directly to the display unit in the cockpit to be sure it worked before taking on the horrible job of routing the new wire. Then I had the bright idea of splicing the old wire into the new one to avoid dismantling the whole boat to install the new wire. But when I cut the wires I found the following: The old wire is a shielded wire with a single wire in it, a coaxial type. But the wire in the new transducer is a shielded wire with two wires in it. The old transducer, with one wire, worked for 20 years. The new transducer, with two wires, works great now. Both were conneced to the same display unit, the old one for years and the new on just now.

What gives? HELP! How do I splice these two wires together?

Thank you in advance for your thoughts.

Ron
