Hi, I need some serious help with this. I drive a 97 Civic LX and my headlights and dash lights blink while driving. I have a trouble code of P1287 which is some kind of high voltage input problem. I put a new alternater on and it does the same thing. I checked all my fuses and found no problems. I've tried to research this problem but can't find anything on repairing this. I'm about to take it to the dealer and probably get robbed! Please help.

 

Check your grounds.

 

cleaned and checked all grounds, still no change. Changed out ECU, Battery and all ignition components, no change. This ones really got me! Any advice would be appreciated!
