Take the bolts out of the starter one at a time and see if the threads are black if they are you may be loosing the ground to the starter.Take a wire brush to them and reinstall and see if this cures your problem.
If this does not solve it then take a voltmeter and hook one lead to the battery positive post and the other end to the battery cable on the starter.You should read 12V,then while watching your meter have someone turn ignition switch to start position and it should now read less than 1V. If it doesn't then you have either a bad cable or solenoid.
Thanks,I will do so. Is there an inline fuse that I may be missing.
If it is clicking then the fuse should be ok. It is either going to be a corrioded connection or bad cable,or lose of ground to starter
Thanks Chuck, this ones got me.
