Re: Motorcraft Duraspark question...

" From: Tom Jennings <tomj@xxxxxxx>

" I've got an AMC-labelled Duraspark box with the popular "TFI
" upgrade" parts installed. Works great. Got the Ford TFI coil for
" nearly nothing from a yard.
" 
" I installed a 1.6 ohm ballast resistor, a big ceramic job, bolted
" to the inner fender (there is no resistance wire in my home-made
" harness).  The damned thing gets skin-peeling hot -- easy 500
" degrees.  I mean, peel-your-skin-off hot like the barrel of a
" soldering iron.
" 
" The coil seems fine, only a slight temperature rise.  The
" Duraspark box is the same temp as the fender.
" 
" Is this normal?

that doesn't sound right at all.  the coil shouldn't be drawing more
than an amp or two, right?  so we should be talking only a few watts -
hardly enough to get very hot at all.  otoh they must be ceramic for a
reason...
