Blowing Fuses

Everytime I connect the ecu wire to my relay the fuse blows immediately. I dont know whats going on. Any ideas would be helpful.

You'll be needing to give up some more information.

What ECU, what chassis, and list other pertinent mods like, wideband, knock box, boost controller, etc?

Also, most importantly, what wire, what fuse, and what relay?

Sprint RE, FC, Nothing else is connceted at the moment. Im just trying to get power to the ECU. it was working for a while then it just started blowing fuses. I have no idea what I did wrong.

I have been checking stuff. Its only the ECU fuse even without the ecu itself attached. I tryied different relays and testing those relays with other systems like the Ignition, and fuel pump on the same 10 amp fuse but as soon as I connect the ECU wire the fuse blows.

I have the solid black wire to chassis ground, the Black-White connected to the battery, the RED/RED-White wire spliced together into one wire to the relay.

Ive blown 12 fuses so far and it happens even with the ECU plugged into the harness

If you are wiring it according to the instructions in the quick start guide. I take it the fuse blows when you connect the wire that in the instructions is labeled "12V from main fuse"

and that it is the main fuse that blows

And you are saying it blows whether or not the ECU is connected.

Go back and more closely examine your connections at the relay and the splice you made of the 2 power wires.

The kinds of problems I've encountered are things like a stray strand of wire that got out of a terminal and is now poking out and creating a short. wires that were stripped too far back and bare wire is exposed outside of the connector.

also verify that you do in fact have the relay wired properly according to its wiring diagram.

Let us know what you find.

I figure it out. The battery wasn't properly grounded to the starter.

Thanks for the help
