Default electrical problem or cold weather?

2003 FLHT with carbeurator.
I noticed my voltage meter going up and down, up and down, along with my head/spot lights. It did not matter what the rpms were doing other than at idle. While sitting and warming up, the voltage was fine. No fluctuation. When I put it in gear and started up the road, I noticed my lights got real dim then gradually got brighter and brighter then they got dim again and kept doing this all the way home. It was about 40 degrees out. I took it out last weekend in 70 degrees and no problem.I searched the forum but could not locate anything similar. I was wondering if it was just the cold weather.

Have you checked your battery cables and grounds? It may be a good place to start. Also, check the output of your alternator by a volt meter at the battery.

I hate electrical gremlins

Good luck

Just a guess, but it could be a weak voltage regulator, it is very exposed to outside temps and it mayonly fail when cold.

If that's the original battery it might be time for a replacement.
