Okay... okay... I have a funny installer story that honestly made me speechless and question all my years of knowledge.
While building that black truck, of which I posted pictures of, one of the installers was hooking up the two high power alternators. I believe they were 250 amps each. When hooking them up, he hooked one to control the electronics to run the truck, and the other to power the amps. I asked why he was separating them, and he said it's because the truck's electronics can't handle all that extra amperage. I explained amperage to him and he said "fine, if you want to take the chance of frying all the electronics in his truck, the I should hook them up myself and take ownership of it when the truck burns down."
Now, this guy has been installing for almost 20 years. I could tell you a lot of bumbles this guy did, but.... I'll save them for later.
