ok bike is not charging i have tested as i seen on this site (done a search lol)stator shows it puttin out rite got a new voltage reg and hd battery.where the voltage rg goes into the computer board have a prob there my prob is i dont understand how it charges from that board does it goto the starter some how and back feed to battery?seems like the wire from the voltage reg would go strait to the battery.sorry if sound stupid just very lost at this point.

 

Are you sure that it's not charging, instead of losing a charge. If it is losing a charge, use an ampmeter with power off and check for amp draw, shouldn't be any. If there is, start pulling fuses till you find the one causing the loss. At least you'll have narrowed it down to one circuit. Maybe you've covered this already, in that case, I'm out of ideas.

 

not charging as in the battery isnt holding a charge? or not charging as in trickle charger isnt charging? the fuse in my charger was blown, took me a while to figure it out, but its either the really cheap or really expensive things to fix. replaced the fuse and it worked.

 

Wideglide you've got the basics. The plug from the reg. to the stator receives the AC voltage from the stator to the rectifier/regulator. The rec/reg. converts the voltage from AC to DC volts and depending on your year of bike there is a little ground wire for the rec/reg. The wire back to the electrical board main fuse or main circuit breaker controls the amperage back to the battery via a common connection on the starter. The rec/reg controls the amount of voltage and fuse/circuit brker controls amps.

 

thanks guys gettin like 18 volts at stator running and will go up with idle up.then did a pin to pin check its 0.and pin to ground is zero resitance also.new voltage rg not showing any power when unplugged you know the power drain check lol.at the battery running or not running shows same thin even if idle up same around 12.5 volts.seems that should be moreat battery.just hate to buy everything again.just dont know where to go guess change stator first even though it shows good output.regulator is new.uhhhh

 

Not knowing what year bike we are helping with is a little difficult. Example an 02 carbed dyna will charge at 13.2 vdc at idle and 14.2-14.4 vdc at 2200 rpm. My 05 will charge 14.2-14.4 vdc at idle, constant. How old is this battery? What is your voltage at the battery while bike is idling and at 2200 rpm? Have you open up the primary at the derby cover for the burnt smell if the stator cooked itself? Never disconnect the reg. and stator while the bike is running you could ruin the stator.

 

Don't know if I would change the stator yet, sometimes these things require a step back to square one. If the stator is putting out ample power it would be a waste to replace it, all the grounds are good? I ride an older hd without the computer module you mentioned, maybe that's the bad boy. If you have a service manual you should be able to confirm proper operation of that. I here where you're coming from, you replace everything and then come to find out it was something stupid. Go with what you know, if the part checks good, don't waste money replacing it. We're missing something and you'll probably smack youself on the head when you find it. Good luck.
P.S. have you done continuity checks on all associated wires, maybe one got pinched somehow?

 

mine is a 02 sorry its charging at 12,1 volts and when at 2200 rpm its at about 12.5 as for running with the rg disc from stator thats how others on the forum says to check stator.no have not checked for a smell but i will.thanks for that idea also battery is brand new hd battery

 

It's a little late for me here, but I'll check tommorow, somehow 12.5 doesn't seem right for the proper voltage for charging. Back to square one, you had no probs and out of nowhere it just quit charging? I think most battery tenders monitor at something like 13. something.

 

yea end of last year started this.i have a drag spec voltage regulator someone told me thats prob the prob its bad to get hd one.everyone i ve talked to said as long as i did the 2 checks on the stator with the results i got that it was good has to be v regulator.
