I have a corrosion problem with the positive battery lead going to the starter. If I pull up hard on the cable it gets enough contact to energize the starter. Left on its own there is not enough power reaching the starter for it to crank the engine. The local Ram dealer (Burns Motors) refused to service the vehicle as it is over 10 years old. Does anyone have a suggestion as to who might be able to correct my problem in the Pharr ? McAllen, Texas area?
