Greetings all. I hope someone can help me with this.
I took my 2004 AA 500 on a 300 mile ride this weekend. I had no problems outbound, but on the way home tonight I experienced the following:
After about 1.5 hours of (mostly) 50 - 60 mph driving, I noticed the voltage screen dropped from its usual 12+ volts down to about 10. I knew something was wrong but continued driving. About 10 miles later, the voltage dropped to 9, the EFI light started to flicker, and the scooter began to sputter. Fortunately, I was close to an outlet mall (how very appropriate ) so I pulled up to an outside (electrical) outlet and plugged in my charger. After about 30 minutes I was on my way again with the voltage showing 12.2. I was able to run for another hour before it happened again; this time about 5 miles from home. Once again, I plugged into a convenient outlet. Ten minutes later I was back up with the voltage showing 12.8. I am now safely home and the battery is charging.
My charger is an Xtreme XC100, a pulse charging unit. The battery was installed last fall and has been kept connected to the charger when not in use. I have not experienced anything like this recently. The first time I plugged it in tonight, it flickered between 50% and 75% charge before dropping down to the 50% range. The second time it was steadily on the 50% indicator. Now, after about an hour, it shows 75%.
I would appreciate any thoughts as to the first places to check before I start tearing into its innards.
