Hey, guys. I just bought a 92 a couple days ago. When I was in the process of cleaning her out I decided to swap to a newer better battery. I cleaned all the posts and even switched the positive terminal due to corrosion. I got everything buttoned up and when I went to start it all I got was dash lights, in-cab ignition buzzer, radio and window power. The only thing I can hear from the engine bay is a quiet "humm" a few seconds after the buzzer goes off. Any idea what could be causing this? It ran great and started on a dime before I switched batteries. Thinking one of the batteries could be bad I switched back to the original, no luck. Any help would be greatly appreciated!
