I am having a problem with a fuse that keeps blowing and the service people can not pinpoint which of the 5 devices connected to this fuse are the cause. I believe it is AP1 located under the seat. The battery and alternator were replaced when it first happened. After the fuse was replaced the first time, drove it, made a stop , restarted it , and it was blown again. Now it has been several days and it is still working. When it blows I have no controls - speedometer, gas guage, etc. Any suggestions would be appreciated. Thanks
