[Supras] MkIII: Something screwy with cigarette lighter socket?

[Sean Cavanaugh]

the cigaret lighter has a smal thermal fuse in the back of it (I blew mine 
once, pain to replace) that may be somewhat dated and the lower voltage is 
causing some unwanted resistance.  I think yer inverter is just too finecky.
