I have an optima red top that i moved to my bed a few months ago and since it rained like 2 weeks ago it has been acting weird. it doesnt seem to be holding a charge. if i run my stereo for a little while the truck doesnt turn over to easily and the cd player goes to error. i have my cables all ghetto rigged using a pair of jumper cables and it was working fine up till the rains. Also, the friday it begain to rain i drove to laughlin and back and on the way back i was playing with my lights we took Rt 66 and it was pitch blac and i turned the off road lights on and my friends at work said i coulda been drawing to much on the battery they recomended a high out put altenator, because i may have killed the battery. make since?
