2n ignition problem

I've lost count of how many times you've posted with your 2N ignition problem and each time you seem to want to blame your ballast resistor for your problem.

Repeat after me....for a frontmount OEM 6 volt ignition coil the desired voltage at the coil terminal is about 3.5 volts (3 min, 4.5 max).

As for your battery dragging down to 4 volts when your starter is cranking, thats kinda normal. All batterys get sucked down when they are trying to turn over the starter. Yours battery howsomever, may be a little weak in that area. This could be just lack of a good charge or it could really be a bad battery with the plates sulphateing up. Recharge your battery. And yes, even a bad battery will still read 6 volts EXCEPT when under load. Its called ampacity. (I think)

Since you have reported that the engine has started in the past, I would tend to discount "poor engine performance" such as low compression as a cause for nonstarting.

This time, given your general description, I would tend to suspect a bad battery, they don't live forever..... ...Dell

I really respect your opinion. I guess this is the first time I suspected a ballast resistor. the battery is new by the way. I have never had the voltage reading stay at 4 volts at the coil. I know the 4 is the desired reading but the voltage does not get up to 6 volts at the coil which it should be when the points are open. If the voltmeter fluctuates when the tractor is turning over from 4 to 4.3 or something like that does that mean the points are opening and closing. It seems like there should b e 6 volgts at the coil when the points are open and there is no 6 volts .

Thanks for your

Meanwhile, this is still not getting your tractor started. You said something, always reading about 4 volts at the coil. If you never read 6 volts, (which means points open), I would suspect that eather your points have slipped closed or your points attaching screw has lost its insulation and you are "shorting out" your ignition points. Same effect, no sparkies.

The fluctuation that you observe when cranking is probably your starter being loaded down, most likely by pushing up against the compression.

I sure want to read a "success" message..... Dell
