It's hard to believe but after 13 years I have added a stereo system to my rig! And power windows and door locks! And now the alternator went belly up, had it rebuilt and the problem is the same as before the rebuild; the power windows go up SLOW! Nothing is binding, the window rails and channels are straight, etc. The alternator is 78 amp. The stereo, CD player, etc... I don't know how many amps they draw. My question, if I go to a larger amp alternator (any recommendations on what size) will this improve the speed of the power accessories I have? Thanks!
