New headunit keeps blowing fuse help!

My friend installed my new dvd/nav touch screen pop out headunit for me and it keeps blowing the parking light fuse I believe? My taillights dont light up and neither does the instrument cluster however the headlights do work and the running lights don't. The stereo still works. I put in a slightly higher fuse and that blew instantly as well. Something has to be wired wrong, correct?

Yes you have a short somewhere. SOmewhere you have an unwanted path, check all the connections, please tell me he did not use crimp ties, or scotch locks....

But fyi you should NEVER EVER replace a blown fuse with a higher than spec rating. This will cause unwanted high voltage to travel through, frying anything that is on that circuit which isnt designed to see that high of voltage.

Definitely a short, I would check any wires you recently have worked on or near. Butt connectors are OK but solder and shrink tubing are best.

X2 on using a higher rated fuse, find the cause of the short and put the proper fuse back in

lol, yellow edge it wont let higher voltage threw think the term your looking for is amperage but either way your right on the dont use a higher rated fuse... great way to melt wires and start a fire... im guessing that he hooked the dimmer input wrong or didnt at all and its hitting metal somewere and shorting out... i never install mine but alway heatshrink over it to protect it from shorting
