Re: (ET) E141 mystery
Your ET has the infamous "Brain In A Box"® Charging and Control
System. My advice is to find somebody that is still familiar with those,
and
do it post haste. Bill Gunn did one of those for a customer of mine fifteen
years ago, and it was NOT inexpensive.
And, since Bill no longer is supporting that product, resources are
certain to dry up quickly. :(
