Recently I had my oil changed on my '06 Deuce. Since then I have had problems with my bike keeping a charge on my Battery. It will run for a few days then I get the dreaded CLICK from not enough juice to start the bike. SO my question is, after searching the forums for tips on how to check for shorts and bad grounds and faulty stator problems, I unplugged my Stator wiring harness to find OIL dripping out of it.. I can only guess that when the oil filter was last taken off it dripped down causing it to short or ground out. Could this be the problem why my bike is not charging. If so what would be the " actual"reason as in what is the oil causing it to do to lose power. Is it using the battery even when the bike is off? Also if this is a problem what is the best way to clean this oil out of the harness to insure it is all out? Any help would be great! Thanks.

 

Electrical contact cleaner is the best choice to clean up the connector. While it is possible that oil in the connector caused your problem, it is not very likely.

How old is your battery? Have you had it load tested?
How low does the voltage across the battery drop during the start cycle? It should hold around 11 vdc while the starter is cranking.
Your battery should read at least 12.6 volts (75% charged) 24 hours after charging. Less indicates a possible problem with the battery.
Charging voltage should be ~14.0-14.5 vdc. Lower or higher indicates a possible voltage regulator problem. Do the voltage regulator bleed test in the manual.
What is the AC output from your stator at 1000 rpm? It should read 16-26 vac, depending on the amp rating of the stator.
What is the battery current drain with the system turned off? It should read miliamps if you have any keep-alive circuits ( ie TSSM, stereo) but not amps.

 

Thank you for the reply.. After running a few test found out it was the battery. The volts were good. Charger was charging to 100% but the amps were just not there. It's a new battery but last year I was in the process of moving and didnt care to my battery and we hit -30 temps and I guess it killed a cell. Just giving a update..

 

I got a defective battery from a local dealer and chased problems for 6 months that always pointed to the battery but it kept passing load tests...I finally just took it back and got a warranty replacement even though it passed the load test they did...no problem after that.
