The last few mornings when I leave work (graveyards) I have been noticing my headlight dimming about 25% for a few seconds and then return to normal for the first couple of minutes. On closer inspection markers and console are as well and at the same rate. Engine rpm doesn't effect brightness. I ride an 04 FXST carb with a "Hippo" build. Ran a continuity, ground and output on stater. All three pins and checked fine. Battery checked as well and all grounds are clean. About all that's left I know of is volt regulator. Just wondering if there is anything else to check before I spend the cash and just missed something stupid. Thanks
Check the ground for the regulator, check the battery connections again, inspect the battery cables, they can corrode under the sheath. Check your ground at the handlebar riser.
Just curious why the handlebar risers? But will do.

It's just one of those forgotten grounds that can cause mystery issues.

and quite often it's missing as someone has changed bars, risers,etc, etc and didn't see a need for it
Back in action. Finally got new voltage regulator in a few days ago. Went to install it and the 30 amp main breaker was cracked and the post pulled out. Started calling around and just happened to get one of the wrenches at Shreveport HD when I call the parts dept. Looked up their supply and was out. I told him it was my primary ride and said my local Autozone would probably have one. Be on the road today. Sure enough they had one. Just had to remove the little mounting bracket and fit perfect and works like a charm. Something to know if out on the road sometime.
Good find. That relay has been discussed as a common problem many times here. Most replace it with a 50 amp. Glad you're back up and running.
Most replace it with a maxi fuse.
