I have a '92 Honda Acty HA4 It has been parked at the deer camp for a few weeks. I started it up on opening day, to let it warm up. When I turned on the headlights, they flickered a little, and then came on just fine. After about 15 minutes of letting it warm up, I got in to head to the deer stand, and noticed the lights looked dim. The engine died, and it would not start again. So, I had to walk to my stand. When I got back from hunting it cranked right up again, but later died, and the battery was now too weak to start it again. We put a tester on the battery and it showed just under 12 volts while running, but when I turn on the headlights, the volts drop to about 10 or less, again, while the engine is running. My question is: Is it the alternator? Or, is there something else that could have shorted out to be causing this situation?
