Sawdust,

This is exacatly what tech support has tod me that the yellow wire units head plug was not heat resistant. I wish I could get the old unit anyway since I am really un-happy with the micro deans 16 gauge wire requirement. I am actually begining to kick myself for chopping a hole in my fuse for this sullivan product which seems to get some rather lousy reviews and thus far my review would be highly negative based on my initial problems with it. If it is supposed to work with 1.2 volts then it ought to. They should spell out the current needed to power this unit and they could dispose with the micro dean 16 gauge power hook up. If you need 3000maH and up then like I have had to you go get it. I will keep you posted.
