From: "JohnF" I just had UPS destroy an engine hoist (lots of big steel parts) and wonder how KOlb packages and ships the wing spars and 'fuselage' tube. Thanks for info Read this topic online here: http://forums.matronics.com/viewtopic.php?p=497624#497624 ________________________________ Message 2 _____________________________________ Time: 10:12:34 AM PST US From: <1957grnchev@bluemarble.net> Subject: Kolb-List: RE: EIS failures Re: Has anybody ever had a problem with their EIS showing false readings mostly concerning CHT's and every thing else, but not turning on the red warning light? The EIS is computer based.. so if ALL of the indications, and/or alarms are not correct, it's not as likely to be a sensor problem. Considering the age and noted usage, (and having been a electronic engineer and tech for my whole life), you may have electrolytic capacitors breaking down. They have a very limited life span, as compared to any other electronic component, and heat is another problem for them. They are often used in power supplies and in the filtering. Depending on your power source, and how noisy it might be.. electrolytic caps see major constant fluctuations across their terminals. Not an exact correlation, but think of bending a piece of aluminum back and forth over time. Many times, to service old equipment, ALL of those caps will be pulled and replaced! They can usually be identified as a small aluminum can, with a heat shrink cover, which includes a Plus or Minus sign on one leg, and the value and rated voltage. They often swell, or even pop their top, but some times the effective value just falls too far from nominal. I would assume the circuit is using a voltage regulator, intended to keep the microprocessor and associated input conditioning circuits happy. But if a input cap fails, and you have excessive voltage spikes on your buss, it can take out a regulator. You would need a scope to see that, but you might be able to get a digital voltmeter to read the Vcc. If you can power the unit with a known good battery of correct voltage, that would eliminate problems with your AC buss, as it too has a regulator circuit, and likely electrolytic caps in it as well. If you call the MFR, they will likely want to know voltage readings. Post again, if you have more questions on it. Be safe! ________________________________ Message 3 _____________________________________ Time: 10:19:11 AM PST US From: B Young Subject: Re: Kolb-List: How are spars shipped? I don't know if they have changed their procedure. But mine came in a 15 - 16 inch diameter cardboard tube 3/8 inch thick maybe more Boyd Young Do not archive ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
