Publicly embarrassing myself for the sake of others: Occam's Razor never fails.

    I recently posted about a "bad pot". The solution warranted a thread of it's own to serve as a stand alone cautionary tail.

    First this...
    http://pespmc1.vub.ac.be/OCCAMRAZ.html

    I spent an inordinate amount of time tracking down an unnecessarily complex solution before considering the possibility of a simple one. A very simple one; a solution that anyone who has worked with electronics for as long as I have should know to try first. If I had been at work I would have been supremely embarrassed and maybe even chastised.

    I sprayed down the pot with contact cleaner.

    I don't know how old you are, but at 61 I find that I don't go for the complicated solution first as often as I used to. I still do it, just not as often. :)

    lol.. yep. Take the guitar apart and then realize the amp wasn't on.
    Every once in awhile I do something like that. Maybe not as extreme as the amp wasn't on but about as dumb.

    The old man that broke me in on the maintenance crew in the factory taught me that as the first rule..Look for the simplest thing first and save yourself a lot of work..
    We'd get a call to come to the press room (first thing in the morning) because someones press wouldn't start..
    When I'd get there I'd see right away that the night operator had thrown the main switch at the wall..Or they had turned the air valve off..
    So 10 or 15 minutes of production is lost because of a simple little thing..lol..
    KISS rules..

    I worked maintenance 26 years. I bet 30-40% (being conservative) of unscheduled repair requests fell into the category Operator Headspace. It happens.

    Well the thing that bugged me was there was a foreman and a die setter/leadman there that should have seen that..
    I could have been using that time on an important repair (or finishing my morning coffee)..

    Working on F4-C/D Phantom II attack radar in the Air Force broke me of over-complicating matters. Most radar related problems existed between the back seat controls and the back seat itself. Military PEBKAC in a way.

    I bought a Dean Thoroughbred Deluxe used so I tried it out before plunking down my duckets for it. The neck pickup was very intermittent so I mentioned it to the salesman. He immediately had their tech look at it where after digging around in the back of the selector switch cavity, he deemed it a bad selector. They threw in a Switchcraft switch that I would put in myself for a $50 cut on the sale price.

    It was a bad volume pot, just as I had suspected. The tech felt otherwise so it cost them money for the cut in price and the cost of a switchcraft switch.

    In tech-speak, it's referred to as an ID Ten T call. (Write the number instead of spelling it.)

    ........look on the bright side, from your original post you now know that in the event it needs replacing you will need a fender replacement part or source a 250k reverse log (C250 = reverse log) .

    Exactly! I also learned the difference between CTS and Alpha pots.

    I picked up my troubleshooting process from working on my cars in my late teens (out of necessity, not hot rodding). Go with simple, most likely and easiest to execute option first. Last thing on the list? The one that takes the most labor. At least that way, if it is the last thing, the whole system has been gone over top to bottom, so it should all work great for a while.

    We would shorten that one to simply an I/O error. (idiot operator)

    Agreed. Since life started whacking me early, I've had two simple things happen at once. My Volkswagen beetle coasted into a gas station, totally out of gas, and even the carb's float bowl was empty, because I had to crank it a long time to get that filled up. One frustrating day later, after going over the whole car from top to bottom, I discovered that the distributor's condenser had failed at the same moment I ran out of gas.

    Zero turn riding lawn mower will not start, not cranking. Attempt to jump start. Install good battery. Break current battery's positive post while removing. Lose mower key, using pocket knife blade instead. Still won't crank.

    Mower sits in middle of yard. Ambulances are standing by while I use push mower. Twice. It took parts of five days to mow entire lawn. Twice.

    Mower must have certain controls positioned properly to start such as parking brake and control arms in neutral. If there was a seat switch it was removed prior to my purchase. The blade engagement switch must be pushed down in the "off" position. Crap. Geeze I'm a dummy. What a moron.

    New switch with two keys, $22.

    +1 for contact cleaner on pots and switches.

    Don't be too hard on yourself. We've all been there.
    Engine cranks but won't start... check everything imaginable. Except to see if there's fuel in the tank.

    On a related note, a company that I used work for once supplied rented office equipment for a MENSA conference held here back in the '90s. I was on standby that weekend and got a rush call for a large format QMS printer(which used HP mechanicals). One of the conference principles gave me an earful about that particular printer, calling it "rubbish, absolute rubbish", even though it was new right out of the box. When we got to the area that the printer was located he explained that no matter what anyone did, the printer just sat thaere and refused to accept any print job. I looked down at the desplay, read what was there, and pressed the "on line" button. The printer began spewing out every job in que and ran for nearly forty minutes or so,....
    When the printer finally went silent I looked at the man, who was still red faced, and asked,"how do I apply for membership in this organization: I think that I might very do well as a member,...." . I received no answer from him and no other calls for the rest of the conference.:D:D:D:D:D:D
