I have a new altinator that puts out better than 13. A new battery and a new voltage regulator. The car will run fine with a new voltage regulator for anywhere between 5 hours to 5 months. I fried another voltage reg the other day, opened it up to find that the lead wires to and from the coil wrap were toast. I replaced the lead wires checked for proper charging everything checked good and it only got me about 5 miles. Any ideas?
