I think I made a bonehead mistake. I have a TO-20 that would not start. I thought I had a low battery as the engine was not turning as rapidly as I thought necessary. I have a 6 volt system, that still uses a generator, regulator etc. I took my truck and tried to spin the starter faster by jumping directly to the starter pin. I still could not start the engine, now I don't think I have any power to the points. Have I fried something in my system? Since I don't have diagnostic gauges, How should I determine what is wrong? All help is appreciated...I need a simple step by step plan of action to determine my problem and find a solution.

A quick update for you.

I charged the battery and tested for fire at the points and found I do have power to there. I started the engine and it ran for about five seconds and quit. It would not immediaitely start again. I waited a few minutes and the cycle repeated itself. It didn't run long enough to see how well it was running. Does this sound like an electical problem or a problem in the fuel/ carburator problem. I think my governor is also messing up some as the idle has never been real consistent, with some sputtering and some acceleration in speed while in idle mode. Any ideas or suggestions on what to do or check next?

BJ It is very unlikely you damaged anything, by connecting directly to the starter you bypassed everything else. I suggest you look to the fuel system for the start/stop situation. Start at the carb and check for full fuel flow. Disconnect the fuel line and if there's only a trickle begin cleaning all the way back to the tank screen atop the fuel sediment bowl. Attaching 12V jumper cables to the battery is a good way to destroy it and starter switch. your method is the safest, but remember to put it in NEUTRAL! BTW, use "0" gauge battery cables, the 6 gauge-12V cables will not carry enough current to the starter.

Sometimes the coil will get hot and cease to function properly. It will be fine when cold. Hard to test coil, however. If you suspect that, replace it and if it was the problem, fine; if not, well now you have a spare coil. Another thing to look for, if you suspect fuel problem, is stopped up fuel filter(s). When it won't start spray ether into intake and see if it starts. If so, probably fuel problem. Gas line might trickle enough gas to carb to start and run until gas in carb runs out. Let it sit, and it will have trickled enough to run again for short period. Clean the fuel line and filters. Just two thoughts on things to try.

By the way, you can start a 6v from a 12v with no problems if you do it this way: Put tractor in neutral. Run cable from positive of 12 v battery to positive of 6 v (that will be the ground on the 6 v tractor). Check again to make sure tractor is out of gear! Then run other cable from negative of 12 v battery and just touch it to main cable connection on top of starter. Tractor will turn over fast. Hope you remembered to take it out of gear 'cause you are standing just in front of the rear tire!

Would it make a difference if I ground to the frame instead of the positive terminal on the battery? (that's what I did by the way) I was concerned after I did it that I may have messed up the regulator or the generator.

Where is the fuel filter located as I was not aware there was one on the to-20 (It is a new tractor for me)

It shouldn't matter if you put your jumper cables on the positive terminal of the battery or on the frame of the tractor with your set-up. I'm sure you checked your battery cables by now.

When she dies, try to find out if you have a spark or not. To check for a spark, connect a spare plug to a plug wire and hold it against the block while cranking. Look for a nice blue spark. This works great in the field. If you don't have a spark, suspect your condensor or coil. It's nice to change your points and condensor regardless when you buy an old machine. If you have a spark, suspect the fuel system. Try not to open up the governor unless you have to!

Your "fuel filter" is probably a glass fuel bowl under your tank. It should be full of fuel and the bowl and little discs should be clean. Shirttails work if your old lady is a good sport. Good luck.

I just replaced the points and condenser before this started to act up. Is it possible I got a bad condenser? I wouldn't think it runs enough for the coil to be bad as typically I thought they had to get hot to act up. Is it possible the coil to be bad if it starts then stops running immediately?

Not usually. Normally takes 5-10 min at least for coil to malfunction in that situation. Other responses on grounding to frame and one fuel filter were good. I was away from computer for couple of days. As other response said, check for blue spark at plug. If spark won't jump 1/4 inch nice and blue, suspect electrical. (Wear a glove.) If it will, suspect fuel. Another electrical trouble spot can be the ignition switch. You can bypass the switch and see if it keeps running. My money is on that right now.
