24 volt to 12 volt converter sharing ground

[rtadams89]

Specific to a 24v to 12v converter like seen here http://www.thosemilitaryguys.com/24-volt-to-12-volt-converter/ , can the 12v negative lead from the converter be tied to the vehicle's frame (and therefore share the same ground as the 24 volt system) or do the 12v accessories need to be wired directly to the 12v negative terminal of the converter? As I cant find a schematic for that type of converter, I'm hesitant to just hook it up and hope for the best.

I use a Pyle brand 24v to 12v converter in all of my trucks and everything in the trucks is grounded to the chassis without a single problem.

Yes you can use the same ground

You can use the same ground. The two circuits are isolated.

A ground is a ground. In my business we run both AC and DC on the same circuit. Ground is a Ground which is nothing but a reference point. Think about your house or business with 2 phases of 120V or even three phase power. It is all a common ground point.

Incorrect. If they share a common ground, they are by definition NOT isolated.

Absalutly correct, As you will find out if not insulated where required. All our inverters run to earth on the vehicle chassis, Except the chargers which are trickle charging both 12 and 24 volt..
