Re: (ET) Cheap Dc-Dc converter?

[steves <ssawtelle erols com>]

Just means that the input and output share a common ground. Should not 
be a problem, except for this scenario:

The ET does not have a chassis ground. So you could have a single wiring 
fault to chassis and not know it. Now you take the DC-DC and install a 
cigarette plug on the chassis that connects the negative terminal to the 
 chassis mount. You now have a wierd short that will cause odd problems 
you can't trace easily. Realize this requires two unsuspected things, 
but most accidents come from two things or more things going wrong.
