That is a very good deduction there martin, now go run off to your books and read what happens to electrolytic capacitors when subjected to variable spikes in voltage over a long period of time. YES their ability to filter is reduced and the result is what? mmm a BLOWN CAP.. well now do you understand or is this in the realm of the "reversable injector"
It is well known that our Alts will give outputs MUCH higher than rated when the regulator fails so why would this concept be so hard for you to understand?
Now before you get your panites in a bunch and spew off a nice flame retort, THINK about why I would respond like this. Helping people is great, but giving out false info is NOT helpful. Get it?
