8n issues

Thank you!

Run the tractor until it quits. Then pull a spark plug wire and check if you still have spark. If you do, then you have a fuel problem. If you don't, then maybe you do have an electrical problem after all. Solve your fuel problem by cleaning three screens (above fuel cutoff, screen in fuel cutoff/bowl and carb elbow) and then establishing you have good flow to the carb. Take the drain plug out of the bottom of the carb and make sure your flow is good to this point. I'd be willing to bet she'll run good at this point.

From the electrical gurus on this board, while the negative ground 6 volt will work, it does result in weaker "sparkies". Your IT-F04 manual has an OK wiring diagram. There is a better one at www.nseries.com. Put it back to positive ground and then see where you are. Remember to polarize your VR after you do this.

Good luck!

Another check-since you have a start-run-die problem is the fuel flow. Make sure that all 3 screens are clear and that there is no gunk in the tank such as rust flakes, etc.

There are 2 time/heat related issues with the N's. The front mount coil dies after about 45 minutes or so. Then when cooled for a few hours "works" again for 45 minutes.

The key switch work for about 15 minutes and then dies. After it cools off it works for another 15 minutes or so. If it is not a fuel issue then I would test is the key switch by jumpering around it when the tractor dies.

Good Luck!

Two ways to find out if the generator is on the job if the ammeter doesn't read correct now. First, read output voltage--should be around seven volts with engine at fast idle. Second, take the fan belt loose, disconnet the wiring, put six volts on it and see if it motors. If it motors it will generate. All of this assumes it is an original six volt system. Most likely some previous owner unfamiliar with the system and too cheap to buy a manual just put the battery in wrong. On the other hand could be in some stage of a twelve volt conversion in which case all bets are off. If any of this isn't clear feel free to enquire further.

Your mileage may vary

After you change it back to positive ground (And the positive ground didn't have anything to do with the Brits, way back then it was common in the US of A) you'll have to watch to see if it charges, if it doesn't you'll have to polarize the generator to get it back to the proper magnetic direction, just takes a second.

Good luck.

Well, today, we buy new cars for our "girlfriends" and FALL OUT anyhow. Seems like to settle the divorce, she always keeps the car.

Well, I sold the Spitfire for a small loss, BUT I kept the Hamilton clock that was in a real WWII SPITFIRE. Have an older brother who was on B-17's and was stationed in ENGLAND.

He, brother, was write. THEM Englishmen just like to "tinker". You always are tinker'n with them TRIUMPHS. The orig. owner's manual said to do this or that just about every 50 miles. After all, over there that was about 1 month's driving.

Well, I personally knew the Dutchman who received a "royalty" for every TRIUMPH sold in this country. Both of my early "heroes" are gone now.
One of them was STEVE MCQUEEN, and the other was just a "simple" DUTCHMAN! TRUE, ON THE LOGS.
