Bare Posted December 3, 2004 Share Posted December 3, 2004 couple of points.. Space Shuttle is ONLY crimped..Vibration is an issue.. using crimping tools that are pricier than the Average Caterham and subject to constant recalibration :-)...it Takes a Lot of expensive Tools to equal the connection acvailable from a $10 Soldering iron and a few cents worth of Solder. But Hey! nothings too good for a Wiring Harness than would embarass a Chinese made Clock Radio. Link to comment Share on other sites More sharing options...
Robert Lane Posted December 3, 2004 Share Posted December 3, 2004 One of the problems of soldering a crimp joint is that many use an 'active' fluxed solder such as Ersin Multicore. This is what eats the metal. Use a good quality 'non active' flux solder, available from Farnells or CPC. If it's the starter button and it is passing high current I would certainly solder the joint.

Tony C Posted December 3, 2004 Share Posted December 3, 2004 I think this is coming to the conclusion that some people prefer crimping and some soldering. IMHO it probably doesn't matter which is used as long as the joint is electrically sound, is unlikely to corrode or fail in the near future. Personally I can never seem to get a solder connection that gives me confidence. I either partially melt the wire insulation, leave a bare bit of un-insulated wire or the solder joint is dry - on the other hand, nearly all of my crimped connections have turned out OK. As I'm more confident with crimping, that's what I use. I think a crimped joint is less easy to mess-up if the correct tool is used (I use a "Professional" Draper crimper which cost about £12), whereas for me a soldered joint is more likely to be poor 😬 Edited by - Tony C on 3 Dec 2004 10:04:30 Link to comment Share on other sites More sharing options...
elie boone Posted December 3, 2004 Share Posted December 3, 2004 Tony, I never use crimp connectors to solder but only connectors made for soldering. If you worry about corrosion then dip the wire in no corrode grease as used on battery terminals Link to comment Share on other sites More sharing options...
old captain slow Posted December 3, 2004 Share Posted December 3, 2004 Haven't read all the responses so this may be a repeat. In high vibration situations the soldered joint can sometimes work against you in that the transition between the solder and wire strands is very sudden leading to high fatigue at the interface. I think a properly crimped joint will generally give better long term performance. This means using good quality tools and properly sized crimps.

harold Posted December 3, 2004 Share Posted December 3, 2004 Most replies have been empirical .If you wish to have a better /more secure joint than chance will provide, then a specification for crimp or solder considering enviromentle conditions eg vibration level and vibration frequency,humidity, temperature etc, and test to failure useing these variables OR look for a happy medium ?

Normans_Ghost Posted December 4, 2004 Share Posted December 4, 2004 Why spend all that money on sellotape or blue tack. Just twist the wires around each other. Norman Verona, 1989 BDR 220bhp, Mem No 2166, the full story here Link to comment Share on other sites More sharing options...

old captain slow Posted December 4, 2004 Share Posted December 4, 2004 I have always found that a role of tank tape in the car has enabled me to solve most problems. 😬 C7 CDW Link to comment Share on other sites More sharing options...
Trevor Newman Posted December 5, 2004 Share Posted December 5, 2004 So have you actually fitted it or are you even more undecided as to which method of attachment to use im now with the variation of poke the wires through holes provided and twist insulate the above with blue-tac 😬 Link to comment Share on other sites More sharing options...

Normans_Ghost Posted December 5, 2004 Share Posted December 5, 2004 Oliver, he won't hear you his away. Can't believe it takes 3 pages to decide wheather to crimp or solder. Norman Verona, 1989 BDR 220bhp, Mem No 2166, the full story here Link to comment Share on other sites More sharing options...
