I'm usually pretty good on this type of topic, but this is a bit odd.....
Lots of posts on this extremely fast beep from the horn...However I have no VRO, replaced to pulse port conventional pump last year and been running great. Very dependable motor, takes me to far way adventures!
Sunday, planning from Idle, the very fast beep started sort-of quiet and progressively got louder as I went faster...seemed to be based on RPM. If I idled back, it slowely dissappeared---again, progressively got quieter based on reduced RPM (same frequency). Repeated this 3 times before playing it safe, and idled in.
Once I had a wierd "scratchy" noise coming from the horn...and it was bad 12v contact on some of the main power lines....SO this issue, was wondering if somehow the Regulator, Tach or horn itself can show up as this very fast beep that seems to start as I plane and get louder, and reduce as I reduce rpm. 12v switched purple is tied to the Tach and horn too
Water flow out of heads is nice and heavy, Impeller is good/good indication. Head temps are normal and I tested Head temp switches-Have no indication of a heat issue.
