RK Battery Dead

[sprinkman]

Does anyone know how or if you can pull codes from a RK. Friend has a 2003 RK and battery goes dead after a couple days of sitting. He says he has installed 2 different batteries the last couple years. If he rides it is good for a couple days and then goes dead he said battery tender ruined his other batteries. Sounds like some kind of short to me need help!!!

00-03 HD Codes And Activation - Harley Davidson Community hope this helps, check the charging system, the tender should not ruin a battery IMO there is a drain or short some where

No, you will have to start at the battery and work your way thru each system. I would check the voltage at idle first should be at least 13 volts and load test the battery, a dead short there could be the whole problem, Good luck and let us know, there is a lot of help here for you, Hoople is MR. Electricity, if he cant help no one can, Capital Jack

Checking for leakage branch currents is rather tedious, but would be very expensive at the dealer...look here from Self Help tips:

BTW you do not need an expensive DMM...Harbor Freight sells one inside of $8...less with 20% Off coupon.
