Over the last year, Jeremy Goodspeed has become an asset to 1967beetle.com. Here’s another fantastic article from Jeremy in regards to wiring connector basics. If you’re doing electrical work on a vintage Volkswagen, go ahead and pick up this fantastic non insulated German electrical connector crimp tool he’s been able to bring to the market.
After many years of use, even the best electrical connections can develop resistance or connectors can work loose, both resulting in improper conductivity. Anyone repairing vintage VW’s knows the value in using the proper connectors. However, finding both proper and correct electrical connectors when restoring or repairing an air-cooled VW can be frustrating. However, with some basic understanding you will be able to correct circuits and keep your VW alive!
VW used brass open barrel electrical connectors for many reasons. First, brass is very resistant to corrosion, resulting in long service life. Second, non insulated terminals hold very well and make great contact with the conductor. Third, by crimping the insulated portion of the wire creates both strain relief and keeps contaminants out of the wire. These open barrel connectors also make the most effective crimp assuring stable electrical performance. Generally these connectors result in a service life of at least 25 years. Also with VW making their wiring harness with extra slack, an old terminal can be trimmed off and a new one can be installed essentially doubling the wires service life.
