Hey guys, I have a dc1 integra when i was trying to install a band expander all of a sudden the headunit just stops working, it still able to eject the disc just no lights comes on.

I have replaced all the 7.5amp fuses under the engine bay and all the ones under the dash and still doesnt work, i just tried to connect a brand spanking new headunit and still not powering up

Please help

 

Most HU's have a fuse on the back of them as well. Might wanna pull it out, check the connections and the fuse as well. Do you have access to a multi meter?

 

its a brand spanking new out of the box headunit and the fuse is fine

and i can get hold of multi tester , where should it start ???

thanks :D

 

Check and make sure you have 12volts on the red and yellow wire going to the head unit. Also check continuity on the black wire to ground.
