heres the situation i had the edlebrock nitrous kit, but i switched to TNT using thier conversion kit. now every time i try to use it it blows the main fuse. The edlebrock kit uses a 15 amp fuse i've tried a 20 amp with same results. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

What are the amp ratings on the solenoids in total? You'll need to fuse it above that value.

 

Also....check the resistance accross the solinoids. Ask TNT what that should read. You may have a shorted coil. I am assuming you didnt change any wiring or switches? Just added the TNT noids and hoses and jets?

 

thanks for the suggestions guys got ahold of tony at TNT he going to help me out.
