So my alternator went out the other day and it had a warranty so while they replaced it today I went ahead and had them replace my battery cables. I bought a kit from someone on here and had planned to do it myself and that was at least a year ago. Anyway, I do have some slow starts and also my car would run rougher with the AC on as the RPMs would drop to 500 or just under (weber carb, no amplifier). Anyway, replacing those cables made a world of difference in how fast it starts and idles. I have experimented in starting it with my lights on and my AC compressor on while starting (bypassed amplifer so it its on, its on). Doesn't skip a beat. A very worthwhile upgrade. Only thing is I cannot remember who I bought them from, but I know someone can call that out when they look at the pic.
