So my problem is the siren will run all the lights just fine but when the siren sounds for more than 2 secs it blows the fuse. I have the main box wired to the constant terminal on the engine bay fuse box. The siren and switches wired to an ignition power. Then have all my grounds to one point. I have also changed siren boxes to make sure the box wasn’t bad but the same thing happened. Any ideas what’s up? Now the last time the fuse blew it blew the fuse up at the ignition wire under the dash.
