Question about Ford 8n,9n,2n, Tractor Starter With Drive

Ford 8N 1949 cannot start no spark

I cannot get a spark from the sparkplug after I changed the coil, rebuilt the distributor, chaged the condenser and battery. The tractor battery is a 6 volt and it ran fine for years until the starter jammed and I had that repaird. The engine turns over but will not start! I had a few hands in the motor at various times over the last 6 months and wires were changed and I have a feeling that something is crossed. The tractor started a while back when you kept your findger down on the starter button, but then one of my friends tinkered with the wires and that cleared that problem but I now have no spark! Can it be the voltage regulator? I can buy this part for $50.00 Canadian but is this the real problem? Any help would be appreciated and I cant wait to have my little red belly out on the farm.

Hi I am Vortash this sounds like a spark gap problem at the distributor points or maybe a fault in the ignition switch .. but the voltage regulator would only regulate the power coming from the dynamo to the battery and as long as the battery is charging then it is ok I would check the following ... Points gap for a fourstroke engine of the age you say I would have thought no less than 12- no mre than 18 thou .. check the distributor rotor arm and cap are connecting properly ..sometimes the carbon connection sticks and doesn't touch the rotor strip , make sure the rotor arm end is not carbonised .. check there are no breaks in the contact breaker wire .. run a wire direct from the battery to the coil and distributor bypassing the ignition switch and see if it starts then proving a switch fault ..hope this helps regards vortash

Most likely the distributor breaker plate has plastic knobs on the bottom side and it if it's bad it will not fire to test remove wire from points with the ignition on test to see if you have power to the points wire if not then the coil is not powered up, if this is the case try testing the coil for power using a light tester to see if the Positive side lights up without the points connected. If it has power then take an ohm meter and test from the point wire hook up to ground, it you get a reading with the ohm meter then the points are shored to the breaker plate assembly.

I have fire at coil but no fire through sparkplug wires


The problem sounds like it is your distributor. Replace the ignition points and condenser, make sure the points are gapped properly. If you still don't get fire at the plugs, change the distributor cap, rotor, and wires. Points and condenser kit runs $9.72.

8n (front mount distributor)seems to be frying coils, one day working just fine, next doesn't spark at all, New condenser, plugs, wires, rotor,points, distributor cap. Replaced coil last time seemed to...


Had the same problem, but was my fault for bypassing the ballist resistor (my bad). Anyway, I fried the coil. Read all the posts and bought new 12 volt coil (it has been converted before I got it 13 years ago). New points, condenser, cap, rotor. Now it is just my timing is a little off, but I have strong sparky but not enough to fry my coil again.

If anything, keep the ballist resistor. it is needed to drop the voltage to the coil so it doesn't fry.

Have new plugs, wires, cap, coil, rotor points, condensor. Still no spark


Check for power getting to the center top connection at the coil.
Are the points opening?
Are they fully closing?
Check for a grounded connection/wire in the dist?
Be very careful how you set the coil onto the dist.

Ford 8N wont start


It sounds like the conversion was more trouble than it was worth. I won't claim to have the solution to your problem having never worked on an 8N, but I was wondering about the capacity of the points and condenser in the distributor. If the condenser is not 12 V also, it might be causing the points to melt which would keep from getting a spark at the plugs. Check the condenser for voltage rating and also check if you are getting a spark at the plugs by unscrewing a plug, reconnecting the high tension lead, and hold the edge of the plug against the block while cranking using thick leather gloves, insulated pliers, rubber, or other non-conductive material to keep from getting shocked.

Ford 8N will not start when hot


This sounds like a bad fuel pump to me. The only way to be sure is to check the fuel pressure when cold, probably around 45 PSI. Then when it get hot it will drop way down to 10 or 15 PSI. Check the pressure if you can, or change the fuel pump.
