A good many Hi-Fi nerds will stick 'BluTak' to the capacitors to stop them vibrating.. In theory this will clean up the signal. Roger Coils, too. In Germany we have Mundorf Company who does a lot of crazy things to speaker networks. The wire in the coils have tendencies to vibrate and are glued together in a special manner. Would be a good idea to let all these details influence our ignition systems as long as this keeps nearly invisible. Hifi and Oldie have both in commen that all works and it is difficult to judge if it can do better. Quote Link to post Share on other sites

Mick Forey Posted December 9, 2020 Report Share Posted December 9, 2020 Doh, you are right. However, The Master, a renegade alien Time Lord in the Doctor Who universe, uses the phrase "Resistance is futile" in season 14, episode 9, "The Deadly Assassin", Wikipedia - so it must be true, haha.

Andy Moltu Posted December 9, 2020 Report Share Posted December 9, 2020 Gold plating terminals does serve a purpose in preventing corrosion and enduring a long lasting good contact. Speaker wires are a definite area of massive testiculation. Expensive HDMI cables that carry a relatively simple digital signal are another amusement. If a digital signal is readable, it won’t give a better picture or sound going down a better cable. Some coils are resin filled which helps to limit vibration from allowing the coiled wire to move and can’t leak unlike the oil filled ones. Quote Link to post Share on other sites

Steves_TR6 Posted December 10, 2020 Report Share Posted December 10, 2020 Back to the subject...Condenser symptoms! During Lockdown1 i rebuilt a 1974 Honda CB550 motorcycle that had rested unused for more than 20 years with a seized engine and burned out electrics. After i freed the motor ( diesel in the cylinders works wonders!) and rebuilt the carbs I couldn't resist trying to start it with its old/original points, plugs, condensers etc. I did set the timing. To my amazement it started and ran, but would not rev beyond about 4000. I installed new condensers, and changed nothing else, and the motor pulls to 9000 revs Checking the old condensers showed very low capacitance but no shorts. So this fits with the above, a motor will run with no condensers but the arching at the points will prevent high revs and also burn the points out in short time Steve Quote Link to post Share on other sites
stillp Posted December 10, 2020 Report Share Posted December 10, 2020 When I worked at a Technical College one of my first tasks was to make up leads for students to connect apparatus. I didn't trust crimping at first, but I was able to section some crimped joints and had them etched and microscopically examined. Virtually all of the uninsulated AMP terminals crimped with the correct tool showed cold welds. On the other hand, almost none of the insulated terminals crimped with a'generic' tool were cold welded. Pete Quote Link to post Share on other sites
