GLPoomobile 958 Posted August 24, 2008 (edited) I'm a bit concerned about the condition of my CAS. It had been wrapped in insulating tape and looked a bit of a mess, so I thought I'd take a look. Peeling back the tape I've found that the original thick plastic covering had gone brittle and broken up and most of it is missing. Is this a problem if it's in a bad way, or can I just re-wrap the cable? Is the original thick covering there to shield the signal, or is it the bare wire that coils around the other 2 wires that shields it? Speaking of which, the bare wire is not joined at the sensor end, but I presume that is OK after what I was told in my other topic about the shielded wire for the coil/tacho. Also, the sensor itself (drum shaped) looks a bit battered and beaten (lots of little dents). Is this usual? I've got pictures but can't upload at the moment. Does it sound like this is serviceable or should I replace it? It seemed to work ok before I inspected it, but I want everything to work as well as it should.

Tom Fenton 1,542 Posted August 24, 2008 It is the wire braid over the other 2 cores that is the shield. Other than that its hard to judge the condition of it without seeing it. But in my experience they either work or they don't, there isn't really an in between. Share this post Link to post Share on other sites
ifcho 0 Posted August 24, 2008 (edited) I don't understand the purpose of this question... If you think your sensor is knackered just go and get a new one, or a sh one from a scrappy. If it is working and you just don't have anything else to do, leave it as is and wait until it starts to make problems. This sensor is just a magnetic coil, so not much to get damaged in it. If it starts making problems, replace it. You may put some new insulation tape on it and clean it, but I guess you could think of this without posting on a forum Edited August 24, 2008 by ifcho Share this post Link to post Share on other sites

It's nice to be on the receiving end of a patronising reply for a change. You've contributed tremendously. Edited August 24, 2008 by GLPoomobile Share this post Link to post Share on other sites
jackherer 543 Posted August 25, 2008 I had one just like that fitted for ages with no problems but in the end I got paranoid it was going to fail so changed it for a better looking one and put it in the glovebox as an emergency spare. I've had totally unmarked ones fail in the past so appearance is no indication of reliability. Back in the day when I had 8Vs I always put a tachy relay and ignition amp in the glovey and these days I've swapped the tachy relay for a spare TDC sensor along with injection and fuel pump relays which has solved most breakdowns I've had with Mi16s.

DougieSt 0 Posted August 25, 2008 (edited) I've busted two of them taking gearboxes off because the plastic gets so brittle... Both times I've potted them in some 5 min epoxy and both have been good for at least a year. And the cans do have little dents in the end, so not to worry. If you're really worried about the wiring tho, get your multimeter out and check the resistance between the pins, should be 500k (might been 500 ohms) between two and infinite between the other two.

GLPoomobile 958 Posted August 25, 2008 Thanks to those of you who hve provided informative replies I'll check the resistance and wrap it back up in self amalgamating tape, and keep my eyes peeled for an emergency spare. Share this post Link to post Share on other sites
