Hey Guys...2008 Ultra...Finished Install About 5 Days Ago.....Pn4.1000d Amp ..Infinity Kappa 62.11i In Fairing...Kicker 41KSC674 Rear Pods..Stock Head Unit.....Thank You To Haze For Picking Components And Gann For Helping With Install And Everyone Who Contributed With Such Great Advice...Very Much Appreciated....Yes Its Loud...Anyway I Have Amp Set Full Pass And Gain Settings Front And Rear At 10:00 o clock....Both Positive And Neg Running To Battery....Now My New Problem....When Riding ..Everything Is Fine Till I Am Sitting At A Red Light...Than My Charging System Drops To 12v Or Less...Feels Like She Wanted To Stall....Than Engine Light Comes On..Seems Their Is Too Much Voltage Draw.....I Than Shut My Radio Off And Everything Was Back To Normal Again...All Grounds Are Good... Battery Terminals Tight etc.....And Of Coarse Everything Was Fine Before Amp Install....Are My Gain Settings Wrong Drawing Too Much? Were Should My Gains Be Based On This Configuration ...Don't Know Much About The Electrical Side Of Harley's...Possible Weak Battery? Help.....

 

I would start with the connections at the battery and check the battery next.

 

Being that the connections have already been checked I'd have the battery tested. How old is the battery?

 

Do you have a bunch of other accessory items, lights etc?

 

Check Battery...Ok Will Do...Don't Know How old Battery Is...Bike Is New To Me...No Maintenance Records..Bought From A Ford Dealer In Oklahoma...No Problems Before Amp Install But Could Still Be A Weak Battery..Does Stay And Maintain A Charge On Battery Tender...Guess That Doesn't Mean Anything....And No Nemick ...No Extra Lights....Thank You Springerfan And Sbates08....Just Hoping It's Not My Voltage Regulator And Or Stator/ Compensator

 

Neg Battery Post Loose...Tightened Now 13 Volt At Idle With Radio And Amp On....Should Be Ok...Won't Know Till I Ride Again.....Thanks Guy's...Much Appreciated....Usually Alway's Something Stupid.....Do Those Gain Settings Seem Right For My Setup ? Or Hate To Have To Buy A Noise Distortion Detector.At $150....Tried Setting By Ear...But My Ears Are Not Very Good From Working In A Noisy Environment For too Many Years

 

Yes the gains settings are close to where they should be. Hopefully you've got it straightened out now.

 

Thank You SBates08....Hope So....Much Appreciated Sir...Thanks Brother

 

lol. heres one for ya... put basically the same system in my girlfriends street glide, cept we used 4 kappas. rode easily 1000 miles with no issues, stopped at a gas station couple weeks ago with a group of friends, gassed up and went in to use bathroom. im sittin there reading the local paper and my buddy comes in says the gf bike dont start, completely dead
told him to hang tight, i was obviously busy at the moment.... so when i finished i grabbed a cold pop and walked outside to find a crowd around her bike, seat off, bags off and one guy was lookin for a torx bit to pull the fairing. they were pullin fuzes, wiggling shix they didnt even know what it was.
so i just stood there and watched
finally my gf looked at me...half sad, half mad, half embarrassed and asked me..."now what"?
my reply?... check the batter posts?
and yes....i shoulda checked them but had already after 100 mi and after 500
but thats why i like to do my own work after watchin 3 guys who had no idea
but i did appreciate the effort on their part!!!

 

Wow..Yooperhog Hell Of A Story...Glad You Figured It Out..I Get It...I Just Finished This Up As Well Thought I Had Everything Tight And Good To Go...Seems Like The Bolt Just Broke Loose....The Terminals Are So Small That If I Go Too Tight I Will Just Strip It....Need To Throw A Lock Washer In There...Wild Story...Thanks For Sharing Brother
