Re: (ET) Cheap Dc-Dc converter?



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.
