OK here is the deal. New bags, new shocks, remodeling almost done and looking retro and fabulous. For a girl I think I am doing ok. However with my limited knowledge of engines diagnosing problems seems to take forever. But I am learning and am excited to expand my knowledge. So here is my dilemma. My rv runs great and all seems well. However, while I am driving down the road my headlights will become dimmer until they die all together. It will stay running but no lights. But if I turn it off it won't start due to dead battery. I checked/replaced fuses. Did a volt test which said the alternator was putting off about 10 volts. I know it should be about 13-14. So I decided to try to test the isolator. This is where I have questions. I have been reading through archived posts to determine the process. That part I understand. So here is my questions.

1)where is the isolator located? I found pics of what it should look like.

2) Do I test the isolator with it running?

3) If I take the wires off the isolator to see if the problem persists, where do I put the wires to run it and see if the lights still go dead?

4) Where can I find a combiner and what specs should I look for when choosing one?

5) Any suggestions that might help?

My knowledge of my big bird engine is still limited but expands each day and I am super stoked about learning more. Any suggestions/answers would be a great help. This is a project I have taken on alone so while confident I can get this I am a little ignorant as to some technical terms. Just saying you are talking to a determined yet somewhat confused blonde chick lol. Thanks
