On my way home from work tonight with my 04 Harley Sportster .
I didnt notice anything until I got on the Northway .
Head light and turn signal seamed dimmer than normal .
I first thought it was me because of workinf overtime and a little tired .
Drove abought 16 miles and as I exited the off ramp the lights got a lot brighter .
Seamed normal the rest of the way home .
I,l check for possible lose or corroded cables in the morning .
I,m going to put the battery on trickle charge also .
Any one else experience this with there bike ??
Suggestions .
Almost like the bike was running on the battery alone .
I did not notice any difference in the power .
Thanks............

You already have the correct gameplan......

Don't forget the GROUNDS!!!!!! They must be clean and tight as well....

Finally, get your battery load tested......

If all of that pans out, get your Service manual and electrical diagnostics manuals out and start checking your charging system.....

 

What Shovelhead Bob said. I was going to suggest checking the battery ground and find the bikes ground for all the electrical systems also. Tim

 

Checked wiring and cables , all looked good .
Put a slow charge on battery cleaned up terminals and it seems o.k as of tonight .
I did notice the battery conections did not seam very snug when I took out the battery .
