Would you believe I actually thought I had repaired my Lucas alternator myself? Wretched man that I am, I am now ready to replace the alternator. I have seen a freinds TR6 that was running a GM alternator and he laughed aloud when I told him of my attempts to salvage the Lucas unit. So, does anyone have experience with installing a GM unit on a TR7? I am open to anything and prepared for any derision that might be directed my way. The stinker is that my Lucas alternator appears to be working, but the light on the dash is doing that "flashy thing" and has been off and on for a couple months.
