I posted awhile back about a 'warm starting' problem with my 9N. With your help, I realized the 12V battery, ballast resistor, and original coil were not a good combination. I put on a new, square, 12V coil and removed the resistor. Now the tractor runs for 1-minute and stops. (I guess it has to get worse before it can get better.) Should I have left the resistor in? I'm tempted to replace the condenser. If so, is there a difference in condensers (6V or 12V).

DieselDad..... ....I'm so glad Barnabas's reportback about his 9N's hot-start problem inspired you to enquire about your own 9N's hot-start problem.

There are 4-common 9N frontmount ignition runtime issues: 1) runs for about 1-minute and quits; BAD condensor
not yer stated problem 2) runs for about 5-mins and quits; CLOGGED fuel filters
not yer stated problem
3) runs for about 15-mins and quits; restarts in 1-hr; GUNKED-UP ignition switch guttz
could be yer stated problem
4) runs for about 1-hr and quits; restarts overnite cooloff; BAD IGNITION COIL could be yer stated problem

The "infamous ballast resistor" is like an lightbulb; it eather works or it don't. HTH..... ...respectfully, Dell, yer self-appointed sparkie-meister

Thanx for a quick reply Dell !
I had her out in the field doing a bit of brush hogging around 1 hours or so got her back to the house and turned her off tried to restart n/g about 1 hr later was able to fire her up but she died out after fiddleing with the throttle. After she was good and cold was able to fire right back up. Im thinking coil how bout you ?

Depending on the coil type.. you may also nee dthe 'trick ' Dell 1/2 ohm resistor. Though I agree with dell.. replace the condensor, and check the points for burns!

Barnabas..... ....1-minute run time is classic BAD condenser problem. Condenser is usually rated for 200vdc and therefore 6 or 12v is NOT A PROBLEM. ($3, cheap)..... ....Dell

Could be the condenser or the ignition switch. I'd put a jumper wire in the switch and see if that does any thing before I played in the dist. If that doesn't get it to run like it should then its probably the condenser, and if I where you I'd also replace the points also

Sounds like a condensor to me as well. 12V battery with a 12V coil does not use the extra resistor but will still use the original Ballast resistor mounted behind the dash.
