anyone out there that can tell me what it might be my solenoid on rear of frame to left of battery is clicking when i try to start engine???

 

faulty solenoid switch or starter motor
a. connect the starter motor to a battery source that is good (use large diameter wire for this due to the heavy current flow)
b. if the starter motor turns, the solenoid switch is faulty
c. if the starter motor doesn't turn, the starter motor is defective

gonna do exactly that with my 250sx and check things out...will get back to get results and compare

hope this helps
