have an ls swap in my 2000 civic for over a year, but suddenly blowing the fuse for the alt/speed control. it blows randomly but only when i idle. like when im at a stop light or in traffic.
i checked for a short but cant find one, could it be something else?
thanks

 

One at a time, unplug the alternator, primary O2 sensor, secondary O2 sensor, VSS, and EVAP vent shut valve, two way valve, or purge valve to see whether one prevents fuse 15 from blowing.

Also download the Fuse 15 TSB at the link in my signature.

 

thanks, ill give it a try
