content: Hi,Anyone with spare contacts / "fingers" for the rotary selector switch from the Fluke 89 IV multimeter (and, I am guessing, also Fluke 189/289)?I would need at least 3 of them, ideally 4.Thanks!

content: Quote from: woodchips on August 18, 2017, 04:55:00 pmNow you made me curious what else could fit.To be honest, I was tempted to see if I could use some RF "fingers" from a network switch linecard, but it was too "bodge-y", even for someone like me.In any case, please see pircture below, shamelessly linked from Mr. ModemHead's otherwise excellent site:

content: If it is just the fingers then try an old Tek 7A18/7A26 or similar upto 300MHz amplifier, the attenuator switch fingers might work.

content: Somewhere in the pile here I'm pretty sure I've got a broken Fluke 19 which may have the same/similar contacts. I'll try to find it later & take some pics; you're welcome to any bits you want for the price of Aus-UK postage.edit: just found it. Unfortunately, they look very different

content: I can't remember if my 289 has the same contacts (and I would not bet on it)but confident that the 189 and perhaps the 187 should be the same as the 89 IVIt might be cheaper to buy a donor meter going cheap on Ebay that has issues unrelated to the switch areaIIRC, these contact thingies SNAP very easily if bent, non lubed, or battery corrosion has eaten away the shiny coatingBeen there !Good luck

content: Want me to see if I can manipulate myself into a Fluke Eindhoven circle about a km away? They do repairs and calibration if I remember correctly.Current local contact count: 0.

content: Quote from: Electro Detective on September 05, 2017, 10:37:20 amThat is an option to explore, although it could introduce the risk of me then wanting to resurrect both meters.You can see where this is going...

content: Quote from: Asmyldof on September 05, 2017, 11:19:20 amIf this is not a lot of trouble on your side then, yes, please.I'd like to get this meter back to usable condition.Just as a side note, I did contact Fluke support and they were kind enough to offer me a replacement 289 at a good discount (they don't have the contacts available anymore) but, even then, I still couldn't justify the total cost (still in the 100's of £, after the discount).

content: That's why I can make an attempt of manipulating my current local network into trying to find someone who goes to that building daily.My experience with large companies, especially the ones that have some Philips legacy, when the "local front desk" says those parts aren't available anymore, it's because the system says "No Longer in Maintenance" which then often equates to some sod having a box of about a 1000 of those springs sitting on a shelve waiting for a re-allocation, which won't happen, because the device is no longer under maintenance.Or you're unlucky and they are truly no longer in stock.I'll have a look what I can find out.

content: Quote from: Asmyldof on September 05, 2017, 03:48:02 pmMuch appreciated!Yes, I can see how that can happen.Also, even if they have broken 89 IV's just sitting there waiting to be scrapped, they still can't source the contacts from those, as it would likely be against some corporate/government policies.In any case, I'm looking for the part marked with 177 in the attached picture.Fluke themselves called it "item 658341".And I am looking for at least 3 such contacts, but 4 pieces would be preferred.Thanks!

content: Hi, Fluke will not sell parts directly to Jo Public here in UK, I tried.You need to go through a distributor.Since you know the part it is much easier to get the part.I found someone else in this forum recommended this distributorhttp://www.sjelectronics.co.uk/I can vouch that they are indeed very good, I used them to get replacement input jacks.You need to call them and talk to them.

content: Another update on this whole meter contacts saga: it just so happens that I managed to score something like a Fluke 87 III off our usual sometimes-a-bargain trading site.The meter is sick and needs some TLC but, while troubleshooting, I noticed that the rotary contacts, although having a different physical layout, they looked as wide as the slots for the contacts on my 89 IV.Hmmmm....So, I took these contacts from the 87 III and installed them in the 89 IV and, what do you know, it worked!!!I now need to source 3 x contacts for the Fluke 87 III, but I am hoping I'll have better luck than with the ones for the 89 IV.Anyone happening to have such contacts as spare, by any chance?

content: Meanwhile, I have managed to find a tiny bit of contact myself, but the last weeks were beyond hectic and I haven't had a chance to poke at the subject of spare contacts.Will update you by PM if anything happens on that front.

content: Hi, you can use the 17x series, I cut a little the plastic and glued them with a epoxy glue. If you want to see how they are send me email or wassap +34605481877 and I´ll send you a photo. You can buy them inwww.buerklin.com4,59€ each plus shipping, just search for 3084560 in that web or in google "fluke 3084560". In your local Fluke service centre you can also buy them 2,50€ each but at least here in Spain the told me that I have to buy 200 as the minimum order is 50€. Regards
