Hi Andrew,

 

I initially shared your views on soldered pins having fewer problems than crimped pins.  That is until I used “machined” pins for crimping. Using machined pins provided a level of reliability much better than my crimped pins using the “tin foil” pins.  Turns out even better than solder as it did not have a sharp stress point as a solder join may have.  The machine pins have a solid body with a cavity in one in for the wire, a crimp puts 3-4 indentions into the barrel of the pin and secures the wire.  You can really pull on the wire and I have never had one come out.

 

Naturally,   If it is done correctly then just about any method will work, but my personal opinion is that using machined pins and crimping is the best method I have found.

 

There is one downside to using machined pins – they are pricy.  But, then what price for a reliable connection – right?  I only used them for what I considered flight critical connections due to cost and never had one fail.

 

Not suggesting you change anything, just wanted to give you my benefit of going down the same path.

Thanks Charlie. Yes all my earths go back to a forrest of tabs. Pretty sure it will be an earth issue also, as its a new problem on a system that has been working well. Some connections are crimped as in the later part of wiring I got a bit tired of sniffing solder. Nearly all my wiring problems are associated with those crimped connections so I just solder them now as they appear.
