Ford Repair: 93 FORD BRONCO, ford bronco, inline fuse

Question
i got my bronco a year ago. it has 200,000 miles on it, but has been overhauled and has been running great. in the past week, ive have a really hard time getting it to start. i checked the battery, the starter connections, and even replaced the starter cable to the battery, and the solinoid. it started right up, but after it got shut off, and then we tried to restart it, nothing. it just makes a click noise, nothing else. what could be wrong with my truck? is it that maybe somehow my amp for my radio is shorting out my solinoid??? help me please

Answer
Yes it is very possible.Take the amp out of the equation by disconnecting the power wire.It is possible for the new solenoid to be defective.There only $10,go ahead and get another,you're old one might have been the problem.All amp power wires need to be connected to the battery,not the solenoid.You also need an inline fuse no more than 6 inches from the battery.You amp's ground wire also needs to be no longer than 18 inches.Hope this helps.If the new solenoid doesn't help,take the starter off and have it tested.
