O.K. So I went to replace the large center burner only to find that the new part appeared to be damaged, so I re-ordered a new one.  When I had the top removed I discovered a fried terminal on one of the wire connectors, and was wondering if I should replace the entire wire or crimp on a new connector?  and what connector/part number would it be.  The burner i was replacing is P/N 74010159.  The wire that is questionable was red, but it was trapped between the glass and the burner, since when? don't know.  In the attached photo the wire turned white where it was trapped.  Also I've attached a photo of the new damaged burner, I'm returning because I assume this would be burning out in short order?  Oh yeh, i also chipped the glass and will be order a new glass top, needless to say not a very profitable project, oh well...

I would think you can crimp on another connector if the remaining wire is not grounded/damaged etc. test for grounding with your meter. Maybe a job for a megger. Then again since you already gotta pay money out of your pocket, maybe there is more profit margin to replace the wire set. They get a new wire, you get a little more profit...win-win.

I still haven't purchased a megger, do you recommend one?

[DurhamAppliance]

I don't have one neither. Still trying to figure it out. If i understand them correctly I think one may be beneficial in your scenario. I actually included it in my post just to get responses from those more familiar with them in order to help me make a decision as well.

... if the remaining wire is not grounded/damaged etc.

if the copper wire is overheated (dark orange color), cut-back until it's copper color

This is a common failure from the stamped-out terminal connections getting weak over time creating a loose connection.  And the rule with 'lectricity is that lose connections make heat, sometimes lots o' heat, like you're seeing there.  

 

After you've cut back to good copper and you're ready to re-terminate the wire, review the diagrams in The Fine Art of Wire Terminal Crimping album ==> http://appliantology...minal-crimping/

 

Although a megger would not be a useful instrument in this situation, it is in others, like assessing the condition of the insulation on compressor motor windings.  Here's the megger I use, inexpensive and goodnuff ==> http://amzn.to/R8LDGd
