Hi, I'm new here. I searched the Internet looking for a solution to my problem and stumbled upon this Forum. Maybe you guys and help me.
I am building a small yard buggy which originally was a golf cart. It had no engine when I got it. I have installed a one cylinder, 6.5 horsepower engine in it. The buggy runs fine for what I intend to use it for.
Now, here's my problem. I have installed headlights on the buggy plus an electric starter for the engine. The battery is a 12v motorcycle battery. I purchased a "mini", 35-amp alternator to run the lights and charge the battery. The alternator creates a heavy load on the engine. It cranks slow when starting (because of heavy drag/load) and the engine idles very rough. When I disconnect the alternator wire from the battery the engine smooths right out and runs just fine.
I have realized the alternator is creating a heavy load on the small 6.5 hp engine so I started looking for a smaller alternator and thanks to Google I came across permanent magnet alternators which then led me to this Site and this thread.
Is a PMA the answer to my problem? Will it create little or no drag on the engine?
Thank you.
