I recently bought a 2 wire door actuator and 2 relays so i could set up the reverse polarity. I got it all set up exactly how it shows on the diagram on this web site and every time i either put the fuse in, touch the fused 12+V to a constant 12+V, or ground it after i have it set up the fused 12+V the fuse always blows. What am i doing wrong

Make sure you have SPDT relay. the middel pin will be 87a.

That's the correct way you have it wire up. 30 amp fuses is more than enough to do the job. Now look for a pinch wire. You may have put a screw in between the wire unknowingly. Run a continuity test on the wire. Yes, test the actuator too.

Using your meter. What you are doing is testing to make sure the wire are not grounded to the chassis.
