I have a 73 Barracuda with a 318 and I am having a few electrical issues and would appreciate some help.
Problem 1… The 318 is a strong engine but for some reason my ammeter fluctuates after the car warms up. I can drive it but after 20 minutes the car will stall and will not start. The battery has discharged and is dead. I replaced the alternator and this did not stop the problem. What would cause the battery to discharge if the problem is not the alternator. I replace the voltage regulator, starter relay and have had the car worked on by two mechanics after describing the issues but the problem persists. The electrical is original and my next step is a new wiring harness and gauge.
Problem 2….My fuel gauge doesn’t read accurately, it indicates full when full as time goes on it gives a less than accurate reading. I have replaced the fuel gas sending unit but it did not solve the problem. I am considering buying a new gauge.
Problem 3….I bought a new horn and installed it. It work for a minute and then stopped working. I am not getting any power to the horn now.
