I'm sure each of you have seen melted plastic on push on connectors. Lots of
the time you also see that the push on connectors are copper colored
indicating that they have been hot enough to melt off the silver plate or
tin/lead plating that is standard on push on terminal connectors.
This hot connector bounces right back to why Vanagon starter solenoids
sometimes don't work right. Once the resistance builds heat in the connector
or the copper feed wire it can't provide the necessary amps to actuate the
starter / solenoid combination.
