We've inherited a 1946 2n and we are new to tractors. We have re-wired the tractor and have also bought a new starter, new coil , new distributor, new spark plug wires, and new spark plugs.
We verified the gap width between the points of the new distributor (measured when it is wide open) to be 0.015 inches. It was snug at 0.015 inches with a good drag when inserting the feeler gauge.
We also verified that the timing of the distributor was correct by inscribing a mark 1/4 inch from one of the holes of the distributor as shown in the shop manual. By using the straight edges we verified that the points became open at this mark (we used an ohm-meter to verify this as shown in a youtube video we found).
So I made absolutely no changes to the new distributor - it seemed to be correct.
I then replaced the coil, the distributor, the spark plug wires and the spark plugs.
I verified the continuity of the spark plug wires with an ohm meter.
My battery voltage was 6.27 Volts, I turned on the key, and I measured 5.58 Volts at the coil - is this because of the resistor block?
I then cranked the new starter, but no spark!
Here is how I am testing for spark:
I disconnect one of the spark plug wires, and insert a good spark plug in it. I lay the spark plug on the engine block, and I make sure it is grounded by clipping the spark plug to ground using an alligator clip. I also used a volt meter to verify that the spark plug is grounded.
I cranked the starter and still no spark at the spark plug!
I bought 2 different inline spark plug testers - one was a Briggs & Stratton, the other one came from AutoZone. I clamped one end of the spark plug tester to an actual spark plug inserted in the engine while the other end was inserted into the spark plug wire.
Still no spark when cranking the starter!
I have a circuit tester consisting of a light that lights up when voltage is applied to it. I tried inserting the light at the point where the spark plug wires are inserted into the distributor right at the metal contacts.
There was no light from the distributor when I was cranking the starter. Should I see the light flicker from the distributor when I am cranking the starter?
Is there a way to bench test the coil, the distributor, the spark plug wires and spark plug all together when off the tractor? Is there a way to bench test that my distributor is actually firing properly and some voltages?
What am I doing wrong? Any help would be greatly appreciated!
