<VV> HELP: Apparent Electrical Issue

Fri Mar 15 15:19:03 EDT 2013

 There are several issues at work here:
1. These connectors are, in some cases, over 50 years old. The plastic is losing its shape in some cases. 
2. The brass terminals can become embrittled. I've seen some of them with pieces missing and cracks. Not as bad as the German wiring harnesses in VWs, et al, but it happens. 
3. A LOT of us have become used to the utterly bulletproof reliability of modern car electrical systems. At some point given the connections went from less than 100 to over 5000, well, the 60s style connectors just wouldn't do. Hence the Weatherpak connectors, et al. 
4. NOBODY has used an HRPT in ANY new car design in a very long while. Why? See #3!

FWIW I've never had the LM firewall multiconnector fail, but I know others have.  I have heard of several EM firewall multiconnectors failing and my '64 Gbrier overheated and failed.  As Corvairs didn't have connectors that were unique designs, but shared with other GM models I sometimes wonder if the '65 and later designs were supposed to be improvements on the earlier ones.  Note:  This is not an EM vs LM Corvair thing.

 Many of us have. A single data point does NOT make the case!

Why?  I've never had a problem with one in the last thirty years I've been 
running Corvairs!
