I attempted to charge the battery of my 2005 Sienna after the car wouldn't start recently. I followed instructions in my Owners manual that included disconnecting the negative ground. I let the automatic charger on it at 2 amps for about 2 hours. The current guage on my charger got higher during this period not lower (ie, towards fully charged), which suprised me. When I unhooked the cables from the battery (after turning the charger off, of course) and tried to reconnect the negative ground I am getting small sparks at the negative pole of the battery. I am perplexed as to what happened and why the spark? Unless this is telling me the battery is internally shorted?
have the same problem?
