Please let me know any ideas of where I might start to find this problem and where can I find a Hazard Warning Switch that is located on the dash. The tach worked the day I bought it but it seemed as though it was acting like it wasn't getting a good connect and then all of the sudden the temp gauge and fuel gauge quit working . Are these tied into a main junction somewhere, if someone can point me in the right direction I sure need it at point and time

I have found that starting at the fuse block in the engine compartment, by cleaning all the bullet connectors and respective recepters and applying a slight dab of dielectric grease on them before inserting, (If you can see the grease, it's to much), usually solves a lot of electrical problems. From that point, it's connector after connector in the system. Notice I said, it's a starting point and not nessasary a fix. Welcome to Mr. Lucas's night mare.
I agree 100%. The ground strap and how well it's connected is overlooked quite a bit. If this is loose or not making a good connection, all kinds of electrical problems can evolve.
I'll find something else sooner or later.
