I did think that al-yeti. It's about a 50m run but it's hidden along the backs of fencing, under a driveway, across a roof, you know the sort of thing. I did swap to two spare cores in the cable in case one of the others were damaged, (did this on my first visit) but to no avail. 

I've ordered a new Rio now. I'll swap that out and see what happens. In the mean time, I'll still entertain any fresh ideas that anyone comes up with. 

 

Thanks for all your help everyone, I'll let you know what happens. 

Id be drawn towards a cable problem to be honest. What sort of cable is it?

I'm pretty sure it's 6 core cca james.wilson. In what way do you think it might be a cable problem mate? 

Yes, from the description of the cable installation, it would probably make sense to perform some tests on the cores for water ingress Etc.  The RIO's are very reliable. A cable swinging along the back of a fence - less so.

Haha, I make you right on that Galaxyguy. How would I go about testing it? I've 'belled it out' and put my meter on it and it's coming back at under 1k ohm. Does that sound about right for the distance? 

Just replace the cable don't worry about taking old one out and either get external grade, armoured or pipe it

Yeah I guess you're right al-yeti. That's going to take some planning though so I think I'll swap the Rio as soon as it comes and hope that solves it. If not I'll do the cable. 

 

Thanks again guys. 

1k would be about 1000m on copper cable. 1k is too high imo

But is the above with the 680ohm EOL resistor in place

 

Or a 1k instead of the 680 ?

I assumed by 'belled' it was shorted to read.
