I have a 2005 accent that keeps blowing the ecu 1 fuse. It is also showing a code for "system voltage low", and the battery is wet around both posts. I read somewhere else that the alternator could be surging and blowing this fuse. Had both alternator and battery checked at autozone, battery is said to be on the way out and alternator shows its fine. Battery does not show any problems, start car just fine. Any Ideas?? Thanks in advance!
