i have an old 1978 ford bronco. i have been having problems lately with it starting.I have replaced the battery several times and within the last month or two i have replaced the solenoid, starter, and voltage regulator. I still cant get it to start. ALl it does is make a small grinding sound. I tried jumping from the battery to the starter ground post and it started to turn but wouldnt completely turn over. I tthen had the starter tested and it passed.so i kinda think maybe i have the solenoid wired incorrectly but i am not sure can you help with this wiring diagram?

On the solinoid you should have 3 different sized terminals. The harness has 3 different sized wires, unless it's been modified, you can only hook it up one way! put a wrench on the crank and see if you can turn it!
