Hello All!
Long time lurker, just signed up a bit ago.
Introduction thread here

My Wing is having a issue which escapes me. The battery drains at an alarming rate. Here is a quick rundown of symptoms;

Battery loses charge while riding
Battery loses charge while not running
Will stay running if started after the battery has been charged
Will stay running if started via a portable jump box
Taillight dash light will come on while on the throttle
Taillight goes off when engine speed is decreasing or when at idle
Stator reads 6.4v on all three wires
Battery reads 12.6v at idle, and will either ready 14.3v at 3000rpms OR 11v.

Actions taken;
New battery (Three weeks ago- simply replacing the old battery when I realized it had been run dry and the bike was not able to start when the temperature was below freezing.)
Stater wires were all spliced in together(!?!) and badly corroded Stripped out the awful wiring job, and corrected it with solder and heat shrink.
Disconnected all accessories power cables and tied them off. Rode to work, parked and attempted to start the bike - no change in symptoms. Battery dead.
As far as I can tell by connecting my meter in series with the battery there is no parasitic drain. (I did this by switching it to read amps, and connecting one lead to the positive, and one positive terminal - perhaps i did this incorrectly? I got no reading, but should expect something from the stereo.)



Any and all feedback or suggestions would be very helpful. This is my main method of transportation, and I love my bike.

Thanks!

Have you tried pulling fuses one by one to try and pin down the circuit causing the drain?

80% of goldwing electrical trouble is connector related. recheck all connections, battery cables, stator, regulator, ground. you say stator putting out 6volts, is that ac or dc? should be putting out 45volts ac or more @3000rpm. retest stator

electrical problems

most electrical problems are the results of poor connections heating up once the bike is run for several minutes or more,but will usually read fine when mc is first checked
i would bet that the problem is at the regulator connector or the connector at the solenoid,especially since you say sometimes it reads 14v and other times 11 volts

May be your meter fuse is blown or most meters you have to change the position of the + lead to read amps. Try connecting it in series with a small light and the battery to see if it actually works. Also if it has one of these plugged into the regulator take it out and plug the reg directly into the harness.
