We've noticed a strange malfunction concerning anderson powerpole connectors that we bought via AndyMark. When we used the connectors on 18AWG cables the contacts seemed to crimp well, but when we connected two powerpoles together the connection was unstable i.e. the housings fit together well but the contacts inside did not. From our experiance this happens only with 18AWG cables (the contacts crimped on 16,14 and 12AWG cables worked well). The problem might have been caused by using the wrong port of the crimping tool but we're pretty sure most of the cables were crimped right. We are aware that the specific contacts supplied by AndyMark are supposed to be suitable for 10-16AWG cables but they looked ok after we crimped them.
Has anyone else seen this kind of problem and knows how to deal with it?
