Still Blowin fuses %###$$$!!

[Leah and David Mueller]

I am no expert on this, but it seems that there is some short in the wiring
paths that is getting activated with the vibration of driving.  Check all
connectors and follow the wiring maybe having to strip off tape and such
too.  Not a nice job.  Or find someone with a really good electrical mind.
