This may sound like a dumb question, but my cig lighter never seems to allow the battery to take a charge. I have tried Battery Tender and some other brand trickle chargers thru the cig lighter and the chargers all indicate a flashing error light. Is there some trick to using the the lighter connection, like does the key have to be in the ignition or something?
