not sure if this is the right forum, but I'm using a relay so here it goes....

I originally had several accessories wired as shown in the diagram. My problem is that apparently the siren amplifier bleeds off voltage after the relay is switched off, so the strobe light and headlight flasher continue to be powered for a short duration, even after the switch is off.

Is there a way to prevent this from happening?

Thanks!

I should mention that there is no ON-OFF switch on the siren ampliefier itself - the power is controlled by the relay.

Diode isolate the siren amplifier form the other acc's, this will stop the power from back feeding into them.
