I am using a 22pin Weatherpack bulkhead fitting on a cobra firewall. Was having some issues with an intermittent connection on a temp sensor and I've finally found what I believe to be the culprit. Looks like when the fitting was put together, the male pin got deformed and was pressed against the end of the female tube. Connection was made but I am guessing with vibration or heat, there was enough movement to create a glitch in the sensor circuit.

My question is if anyone has any methods to verify that connections on multipin connectors are all good. Maybe don't put the retainers on until the connection is made, looking for a connector that pushes the weatherseal out? or some sign the connection may be an issue.

Looking for any ideas so I don't do this over again.



Depending on the design, and access to view later, you could use a marker to mark each wire as it's pushed home in the connector? That way you may be able to see if butting connectors pushed a terminal out by the displaced marking(s)?

my recommendation is get rid of that weatherpack connector. I cannot even begin to count how many times I've diagnosed something like this, seen a post like this or of one with a melted housing.

It's only a matter of time before it happens again. Even if you did resistance tests to make sure the connection is good, a bit of heat cycling, vibration or a mating cycle and there's no guarantee it will stay good.

I don't have these issues with Deutsch or Amphenol products...
