i am tricklecharging the battary right now it may be 4-5 yrs old, i worked on the taillights yesterday, mabey that has something to do with a dead battary??? i dignosed i wasn't getin power to the left side tailight circut, but the blinkers and rear foglight worked on that side. pass is ok, my dad hotwired some jumperwires from the pass side of the working taillights to the nonworking taillights and they lite up!! we decided to leave the hotwires running from the pass side circutboard to the nonworking driversside taillight circut hooked up to the nonworking talelights, would that drain the batt? i think its in the cars wireing somewhere, i have been hotwireing everything lately!! lol mabey the cold weather drained the batt???
