Running spare hot wires....

Question,

I need to fish a transducer lead through the hull from the dash.... can I run spare hot wires along with it..... meaning, if I tape the wires to the lead, will power going through the spares make any sort of field around the transducer lead, making it inefficient or the like??

thanks

Why would you have a problem if the wire isn't actually used, i.e. "Spare"?

Either way, no problem if the the unit is properly grounded.....transducer cables are shielded.

Just don't try pushing 220 VAC through the wire...lol

If you think more wires may be needed in the future can you install pvc conduit for your needs. Another idea in A longer run would be to ad an piece of cord to use for pulling additional wires in the future without having to fish one through then.

I would pull some poly chord thru to allow you to easily pull what you want in the future.

I have pulled spare wires in the past, howeve most of the time what I thought I would need in the future is not what I actually needed

I'm no expert by any means, but I have been researching a lot especially regarding fish finders. A lot of info points towards keeping the transducer wire isolated from other wires if possible to cut back on interference.

A positive wire that is not connected to anything turned on will not have electricity running through it. DC (direct current) needs something to draw the electricity through the wire in one direction, positive to negative. House electricity is AC (alternating current) which sends pulses of electricity back and forth kind of looking for an appliance.

If at all possible I'd try running one of the wires through a PVC pipe. Instead of multiple spare wires, why not one leading to a fuse box. Then when you find something in the future you want to add just tap into the fuse box instead of a spare wire.

Edit:
I do have years as an auto tech & home building/repair. Wiring is wiring LOL

Internet parroting of old wives tales. Been using individually shielded wire cable on transducers for years.

95% of the time, “noise” is the result of poorly designed electronics, maintenance related issues or deficiencies in the installation of the unit.

Buy a well engineered, good quality unit. Popular doesn’t necessarily mean quality. Install the unit using best industry practices and these problems simply don’t exist.
