I did a quick check of grounds under the hood. The auxiliary ground coming out of the negative connection looks to be original as it is firmly attached to the inner fender. The main ground snakes into the abyss. If someone can tell me where it terminates I can look there as well. I did another check looking at the gauges. At idle, the battery reads about 14.1 on the voltmeter (about 13.7 on the scanmaster). Does this give me any comfort that at least the battery is properly grounded? If so I can save time by focusing on the ground for the gauge. ThanksThanks for your input. Many responses have focused on grounding so I will focus on that next. I had ruled that out due to the fact that it works consistently on first start and when key on without starting but now I am hearing from multiple members that cold/hot can affect electrical flow. I will try to find a more secure ground and also to help the battery ground to the body better and try again. Thanks to everyone who has tried to help. I have always found that Buick guys are the best. That's why I stick to them.
