So I installed a larger alternator because I was going through batteries running my hydraulic pump for my plow.
The alternator had some wires melt inside, not sure what happened but I want to assume it was just a bad alternator.
Second alternator installed, not charging the battery. I went ahead and wired in a digital voltmeter, and a new plug for the exciter wire. I ran the new excite line on a switch, pulling power from the battery. I used a 330ohm 1/4watt resistor. I guess the resistor wasn't enough, pretty sure I fried the voltage regulator inside the new alternator because now it doesn't stop charging. I turned the truck off at 19.2 volts, took about 30seconds
New alternator is hotter than the exhaust manifold.
3rd alternator is on order. What size resistor should I be using? Is 1/4watt to small, I should go with like a 2waty 470ohm?
Any advice is appreciated. I already have the voltmeter and new exciter wire/plug ready to go. Just need to put on a better resistor so I don't fry another regulator.
