Hi all, I found a circuit on here followed it over and over again but i try it and blow number 1 fuse.

What are you trying to accomplish? Guinness World Records will need documentation and witnesses for any of its categories, including fuse-blowing.

As per the title - ive removed the cluster and i'm trying to get an led working using four relays and i keep blowing the fuse in the number 1 slot, i was wondering if anyone had any circuit diagrams.

I make ready-to-use relay boards for CA $21.00 (basically the cost of parts) plus shipping

The circuit I use looks like this:

Thanks for that i'm in the uk so postage might be sky high, i didn't have diodes in mine if thats what that those symbols are?

Postage is not sky high to Europe, just CA$8.00.  Yes, the diode is very important.  I show two in the schematic but only one is needed.  I layout and construct the board from the schematic and needed two different diode footprints, surface mount and through-hole.

As I mention in the post, I'm flexible with this product. I can sell just the PCB, or the parts as a DIY kit or completed and tested units, at different cheaper prices obviously.
