I have a 1949 Ford 8N (SN 238175) which I purchased about 10 years ago.
We used this tractor sparingly and about 3-4 years ago while making a food plot with a harrow the tractor seemed to lose power. The tractor died in the middle of the food plot. I think we could get it started again but after a short time it seemed to sputter and loose power.
About the same time I noticed the exhaust manifold had a leak that the previous owner used JB weld to repair....it eventually blew. I don't think this is the issue with the tractor loosing power but I could be wrong.
The previous owner converted the tractor from a 6V generator to a 12V battery / alternator.
Early next week I am headed north for Michigan's deer season and during my visit I would like to get this old tractor running again.
I purchased (online) a new exhaust manifold, gaskets, studs, brass nuts and a tune up kit....spark plugs, condenser, points, etc.
I also plan to install the 3 lights the seller gave me 10+ years ago that I never connected.
The lights that were on the tractor were nice so the seller snipped them off and handed me some cheap ones made in China.
I'm no collector so it didn't matter to me....I just needed a working tractor to help around the cabin ( in the day light ).
When I get to camp next week I plan to...
1.) Check the radiator and add some fluid if needed
2.) Drain the gas ( from the bottom of the carb )
3.) Clean the glass sediment bowl ( assuming it has one )
4.) Replace the exhaust manifold
5.) Replace the plugs ( after I check the gap )
6.) Remove the coil/distributor and take it into the cabin so that I can replace the condenser, points, etc
7.) Connect the 12V battery ( and bring my charger ! )
8.) I suspect I may have had a coil problem 4 years ago so I'm going to check the "Total Resistance of Coil plus all ignition resistors"
9.) Add Fresh gas ( with stable )
10.) Pray
11.) Pray some more
12.) Turn the key on, adjust the throttle, pull the choke and press the start push button.
13.) Take it for a ride.....hopefully and see if it starts to loose power like it did 4 years ago when it warmed up.
14.) Possible replace the coil
15.) Install 3 lights ( made in china )

BTW - I'm no mechanic and know little to nothing about motors / electronics so bare with me.......
Questions:
1.) My alternator has 1 wire. Does it look like I have the correct wiring diagram?
2.) Label R1 - Is this the "original" ignition resistor?
3.) Label R2 - Does this mean my tractor is using a 6V coil?
4.) Is there an advantage to use a 12V coil?
5.) Assuming the current coil is a 6V coil and I replace it with a 12V coil do I remove R2 ?
6.) The wiring diagram ( see attached photos ) indicates the "Total Resistance of Coil plus all ignition resistors" should be 3.5 to 4.0 Ohms.
a. Is this true for the 6V coil
b. Is this true for the 12V coil
7.) How do I measure the "Total Resistance of Coil plus all ignition resistors"?
8.) What should the spark plugs gap be?
9.) Is there an easy way to tell if a coil is good / bad?
Thanks !
