#1 Ok, so this issue has perplexed me for over 3 years now. I picked up a rebuilt / salvage title 07 GT500 back in 2015. Everything is near perfect however when I wholeshot the car my guages, dash lights, ABS, and stereo power cycle. It's quite distracting and upsetting when it happens as it's usually when I'm trying to enjoy the power this beast has. I've taken it to the local speed shop who wants a ton of money to analyze the electronics and Dyno the car.. So I've physically checked the ground connections which seem ok (no multimeter testing though). considering it's an RPM triggered event I'm suspecting that it ISN'T a ground issue. I've disengage the ABS because when the power cycles it instantly turns back on the ABS creating problems. My suspicion is that the person who rebuilt the GT500 cheaped out on a replacement alternator and either installed a junk GT alternator (not GT500) or perhaps a defective one that maybe sends a surge at 2000 RPM. I just can't think of anything else that involves electronics and would be 2000 rpm sensitive. I sure would appreciate if an expert from this forum could assist as I'm completely lost. 3 years with the car and I can't take it over 2000 without fearing the unknown... Thank you in advance whoever you are who will be taking time out of your day to help me. Carl
