Much appreciated, as always Ron, I mean no disrespect. You are my go to guy on this stuff, lol. I was hoping maybe someone had run across this before and had an easy fix, that's all. I understand I'm an anomaly here, most American Skier owners don't wakeboard, have towers, or stupid huge stereos, lol.
Been doing some reading today on the Natique forums (wakeboarders love them old 2001s)...here is my theory. Under normal operation (no big ass stereo) there honestly isn't a huge load on the alternator. So the voltage regulator is spitting out maybe 13-13.5v with no serious load. Then I drop the throttle, voltage spikes a bit for a second, but the voltage has everything under control. No external load other than the radio.
Now, add a huge amperage draw (my amps). Running along, the voltage regulator is probably maxed out at 14-14.5v trying to keep up. I dump the throttle, but instead of the voltage needs dropping of like they normally would simply powering the engine, mine still exist. For split second, my electrical system is generating max (cause the stereo still pulls it), but the engine is no longer consuming...so that spike nails the breaker with more amperage than it was designed to handle.
That's my theory.
What I'll probably do is replace the breaker, and upgrade the main heading to the instrument panel, and grab a modern alternator.
