Can I cut them down as they are resistive? They just look stupid at the moment

[jaydee]

yes but remember resistance is dependant on length

[Gremlin]

Yes I know, which is why I asked can I cut them down (How much difference will it make)?

[jaydee]

They should be about 25kohm x metre, anyhow if you cut down just an inch it wont make big difference though.

 

Measure the resistance with a multimeter and the length of the lead so you'll make sure ;)

But I want to cut them down by different amounts so they take the shortest/neatest route, some will probably have 4" cut off and some possibly not cut at all

[Gremlin]

Anyone?

I can't answer your question but I can suggest joing here www.locostbuilders.co.uk
There are some very intelligent people on that forum who will be able to answer your question

Am I right in thinking they're only resistive to stop them interfering with radios?

That's my understanding too. I don't believe that 4" cut off will make a noticeable difference (assuming around 12" left)

[Gremlin]

They're around 12"'s at the moment, (as bought) I just want to know if they are resistive only to stop radio interfeance, if so, I'm cutting them down as I haven't got a radio and I wont be driving near anyone else for any period of time anyway

Removing the RF suppression is seriously illegal because of the possible effects on other things, not just your radio. However, my professional opinion, as one fully trained and experienced in EMC, cutting off 4 inches is not going to have a significant effect. If it was my car, I happily would do it.

[Gremlin]

Thank you very much, what else would it have an effect in other than radios, all I can think of is possibly ECU's and if cars have radar speed settings or reversing beepers?

You will be fine following Tiger's advice.  Shorten the wires as you see fit to keep them neat and tidy.  Yes, the shorter wires will have less resistance but that is OK.  It is not going to affect the way the engine runs.  As long as there is a decent portion of the intended resistance left (and there will be) you are not going to introduce a lot of electronic noise in the environment.  And that noise is not going to interfere with electronics around/outside your car.  In short, don't worry about it.

Thanks very much, it annoyed me every time I looked into the engine bay
