Thanks for the advice John, I didn't think that the tach would pull that much of current though, and since the manufacturer didn't supply an inline fuse I never thought about it.

The tach isn't so much for looks as it is function, and at this point in the project it's a troubleshooting device. But of course, this troubleshooting device needs troubleshooting. An ignition upgrade was something I had planned on doing down the line, so it's not that I'm thinking of spending $300 to get a $30 tach to work, but if it also solved that problem, then I could see moving it up a few spots on the To Do list.

While the car does start and (used to) drive, some of the stuff I've seen done to this car make almost every system suspect to me, so replacing the ignition with at least an Ignitor doesn't seem to be too crazy to me. Especially when the last time I messed with points and condensers was with my '77 GS550, and that was coincidentally the last time I ever wanted to mess with points and condensers.

And I'm not sure how to read this one, maybe you guys can help me. But when I finally got the trunk open, I found 2 distributors in the back. Not one mind you, 2 full distributors (well minus caps). So I think that leads me to doubt the quality of the ignition system just a bit more.
