84 fxrt won't start. i replaced battery and solenoid. the starter reay will click each time i press the starter button. the engine sounds as though it doesn't have enough juice to turn over

 

The relay has 2 components. The coil and the contacts. If you hear or feel the relay click the the control side of the relay is OK. You need to find out what the voltage is to the coil side of the solenoid.
If it's good ( close to battery voltage ) then you have to see what the voltage is getting to your starter motor itself when you press the starter button.
Does the engine try to crank? Does it seem to turn over weak or not at all?

 

voltage to the coil side is just over 10-1/2.the engine won't turn over at all. it tries to but it won't. i'll look in the book for the test for the starter and and i'll perform that test next. then i'll look into testing the voltage regulator.

 

The voltage regulator is part of the charging system not the crank circuit.
Ok so your saying the starter solenoid (the one on the primary)is sending the drive out but the motor will not spin. Is this correct?

 

That's my problem too...
Solenoid is new, battery load tested fine - all I get is 1 click when I hit the start button.

I took the starter out I'm so frustrated but for whatever reason I hit the start button & it still does that 1 click, is that normal with the starter OUT?
Seems like power isn't even getting to the starter ??

I took the starter out to test it tomorrow so I posted this out of curiosity
