24v-12v converter ground: SOLVED (1 Viewer)

[nuclearbeef]

I'm about to wire up my 12v stereo in my 24v Troopy. Already has a large 12v converter by the back door.

1) Can you use the chassis for ground on something powered by the 12v converter, or will I have to run 2 wires?

2) Would 24v from the back-up light (sensing for the reverse camera) harm the radio? Camera itself is 12v-24v.

Thanks,

JW

Grounding 12V Accessories in 24V BJ42

I am planning to install a 12V CB and a 12V power source (aka cigarrette lighter) in my 24V BJ42. I have a 24V to 12V converter that I will use to power these accessories. Question: Can I ground the 12V accessories to the truck or do they need to be 'grounded' back to the negative wire that...

Between military vehicle, boating, and (finally) MUD forums; looks like the consensus is that one can ground 12v accessories to the chassis in a 24v vehicle.
