Loader tractor has no spark
« on: September 13, 2020, 12:41:31 PM »
My 1965 JD 2010 Loader tractor doesn't have any spark to the spark plugs. I have put new Plugs,new wires,new coil,new points & condenser,new cap rotor,new ignition switch,new wire from switch, I have power to the coil. Can anybody suggest something I have missed?

Is the rotor button moving? I had a Ford that sheared the fiber pin. That made me slow down quick!!

Does your wiring reflect these setups?

I second the gear pin on the bottom of distributor. A buddy had an old ford truck and the first time ( it has happened several times ) it didnít shear clean. It would run but run bad , could set the timing or anything. Now when it messes up it the first place we look.

Used to get a faulty condensor new out of the box on occasion.  I've got a tester for them around here somewhere.

We had the distributor shaft turned and bushed in our 2010.  It would chew up the inside of the cap.  It always ate points and fouled #4 plug.  That stopped when I installed a Petronix electronic ignition system.  It was trouble free and in the tractor when it left the farm.

Pop the cap off and work or short the points with the ign. on. Should spark. Now pull center wire out of cap and hold near metal and short points again to make spark jump. If that works check to see if distributor turns when cranking motor.

Forgot to mention, you can grab the rotor button and try to turn it both directions and not have to pull the distributor.

Do you have power at the points?

I went through this two weeks ago when I did a tune-up on my Allis-Chalmers loader. Swapped backwards old parts for new, last thing I swapped back in were the old points and it fired right up. The new points were junk, which surprised me as I had gapped, rechecked and triple checked them. Not saying this is your issue but sometimes the culprit isn't obvious.

Seems the only thing left is the coil (secondary windings are open internally) or a bad ground from the engine block back to the battery.

I won't admit I was there ~ a month ago.  Just before dragging it (Ford Jubilee) out to the back forty and putting a bullet in it, I checked the (newly installed and had it running before it sputtered and died) point gap. There was a gap,  it wasn't enough to produce a strong spark.  Regapped the points and she fired right up. I'll deny this if anyone ever asks.

Did the breaker plate and condensor all have continutity to ground?  

Does the coil read low ohms across the posts and open circuit from either post to the spark plug wire terminal?  

You may have a bad primary plug wire.  Ive had that twice.

Try watching a guy on youtube channel named vise grip garage or even deboss garage both have done a number of videos trouble shooting this same type of problem on cars trucks and equipment. one thing you did name is battery. apparently you need enough to get coil excited to fire the plugs. Could check see what voltage at coil is compare that to what battery says should be really close if not theres a bad connection or something isn't getting grounded good. Good luck either way my deere dealer I told them to pith off recently and that ill never be back took splitting my fathers tractor in half to determine I was right the electric pto clutch or brake need to be replaced which is only sold as a set they said but took the expert deere tech $1600 worth of labor to figure why pto when switched off would still spin with no load of implement to stop it.

I read you have power at the points, but is there spark? See post #6 above. If there's spark at points but not plugs could be timing.
