I just finished fixing my simpson meter! I think someone had tried to do some in circuit resistance testing. R18 was burned out. I really enjoyed the description of the circuit with animation. It was very helpful. I spent a LOT of time staring at that circuit.
Great graphics illustrating the function select! 260s are great meters. I’ve purchased Simpson 260s that spent their lives getting knocked off tech school work benches. A little JB Weld, a little solder and those things keep on ticking.
Wow, so on Rx100 and Rx10,000 we zeroed out the high resistance fuse. I never considered that.... I assumed it zeroed so all is well. Great lesson. Thank-you! Merry Christmas!
Can you do a video explaining the range switch schematics? It’s always been a source of confusion for me and I can never understand the path from probes to meter movement. I love your videos and the way you explain everything and highlight the paths in this video. Please keep them coming so the older analog stuff doesn’t get forgotten.
Oh that would be great it’s the multiple layer or wafers with front and back. Like 1F. 1B. 2F. 2b…..obviously you get it. When the range switch is turned 1 detent do the pointers on every level move that 1 detent too? How does the reverse polarity switch fit in to the path from jack to wafer levels to meter movement. My head may explode lol. The 260 in your video would be a perfect candidate. Thank you for even considering it.
@@robbo6460 Witch 260 do have 2, 5, 6, or 7? Yes all the wafer switches move together on each selection. The -DC +DC is there so you do not need to swap leads if the voltage changes polarity.
I have to wonder if possibly that fuse had a load that was at or near 100% for a sufficient time that it was about to open, but the load was removed right before it did. Since it was a slo-blo fuse, it could have had 100% load for a minute or two before it was ready to open.
That's possible. I'm beginning to think someone put the wrong type of fuse in this meter. But still the resistance of the fuse should be only an Ohm or Two.
Great graphics as always. I have been wanting a Simpson. 260 There have been times that I wish I had an analog meter. Used one in my electronics class in the 1970s. How much should I pay for one on Ebay? Series 7 seems like a good middle of the road series.

Thanks. I still have my Simpson 260 I bought when I was still in High School 1960-63.
That's really cool showing how the busses connect. Great animation as always Rick. Thanks bud.
Thanks.
I think animation helps explain this circuit connections, and I think you'll remember how it works.
Can’t say I’ve ever seen a fuse go high in resistance before. Good find!
This is the first time I've run into this. It had me scratching my head for awhile.

The 260 is a timeless classic that every tech should own.
Thanks

That would be interesting. I’ll put that on the list and start on it after the crystal transmitter project.

My favorite meter. Really enjoy your videos.
Thanks
Works great! I love those meters. Simpson is about one of the best really.
Thanks
Outstanding Troubleshooting! I have a 260 series 6 and 8 and now I know what to look for if it has the same problem. Good job!
Thank you
I never would have thought of that, thanks.

Maybe internal corrosion?
Seen that same sort of symptom on several analog and digital multimeters when well intending fuse replacers and ill informed. Thanks for sharing.
THANK YOU!

eBay has a search that allows you to see the prices that items have been selling for, I think.
@@jeffryblackmon4846 THANX!
Thanks.
Yes eBay would give you an idea of value. Simpson still makes the 260 you might check out there website.
@@AllAmericanFiveRadio THanx
@@jp040759 No problem, friend. I knew about it, may have used it, may you find it of use.
Never heard of or seen this before. I' have filed it away. Thanks.
Thanks
Enjoyed your "animation of the switches. Nice job.
THANK YOU!
I have a similar problem with my series 7. Never checked the fuse though.
Thanks
This is the first time I've run into this. It had me scratching my head for awhile.
@@AllAmericanFiveRadio It would me too!
Anyway u can make a video. On how to test resistance and trouble shoot. When my leads won't read resistance at all
I'll try.
@@AllAmericanFiveRadio can I send u mine? How much will u charge to fix mine?
@@AllAmericanFiveRadio maybe u can use mine for your video
@@AllAmericanFiveRadio I wasn't able to fix it . Mine is brand new it came this way.

Love my simpson 260's and my Triplett 630"s
Thanks. Both very good meters.
My Simpson 260 series 7 I couldn't zero rx1 scale. thanks the 1 amp 250 volt fuse was resistive.
I'm glad the video helps. Thank you, and you are welcome.
