You need to supply the same voltages and polarities as the existing power supply does.

Don't even consider just trying it unless you are very sure, you can easily destroy the unit. Just how much smoke depends upon the capacity of the power supply.

The notion that low voltage=safety is only true when touching it due to skin resistance. What really matters is the power that can be delivered.

I suggest that CJ go short out his car battery with a #8 wire and report back once his hands heal up.

Yes, as long as they all share the same common reference ground. (nt) - cheap-Jack 09:15:31 10/31/07 (9)

Yes what? They'll explode and/or cease functioning? n/t - Ugly 12:51:27 11/01/07 (2)

Why chicken out of yr sheer "if" speculation? - cheap-Jack 08:17:32 11/02/07 (1)

The "if" statement was required since the OP didn't specify whether the loads are electrically isolated. - Ugly 10:54:42 11/02/07 (0)
