98 GTX LTD battery drain

[Grim]

I let my ski sit for several days now without cranking it up and my battery is low, reading, 11.47 volts, turns over slightly but won't crank. Is this normal for ski's or should I start looking for something that is draining the battery?

Any one have any ideas?

How old is your battery? Did you fully charge it and have it load tested?

Yes, the battery is about 4 months old, cranks the ski ok, been load tested, it isn't fully charged now because it is at 11.47, but that shouldn't be the case. The only thing that is different is I didn't crank the ski for about 4 days. I checked the stator and rectifier, it charges battery at about 13.3 ish volts when running. I am wondering if there is a normal drain on these skis or do I have a small issue and need to look for the culprit.

The normal drain should very small. You could measure it using a multimeter as an amp meter and put it in series with the battery. If you see a higher current (maybe more than 1 mA) I would try disconnecting major modules to try a locate where it is being used. You could also look for corrosion at connectors or on circuit boards that may be causing current to flow. Also can look for missing wire insulation where wires are rubbing against other wires or metal that is grounded. If you can't find it you could add a kill switch to the battery to easily disconnect it when the ski sits for long periods.
