Before anyone jumps down my throat you have to know this is the first time I have replaced a coil, a set of points condenser. All this is new to me so please be gentle.
I wrote before about a bad coil.
Ok, I replaced the coil that I thought was bad. The new coil I got was from the local IH dealer. I asked if it was 6v or 12v and they said this one was the same. OK?
On the old 6v coil the wire from the resister went to the negative post and the wire to the distributor was the positive post. That is how I wired the new one. Well when I pulled the coil wire off the distributor cap and cranked it the coil wire was HOT. So I plugged it back in. I pulled a spark plug and held it to metal and cranked it. I got nothing until I let off the starter and then it would lightly spark once. I decided to install new points and condenser. So I installed them and gapped the points at .020 and put everything together. I still got the same spark at the plug. Nothing as it was cranking but a slight spark as it stopped. I read on a thread somewhere here that the wire from the resister needed to be on the positive and the wire to the distributor was the negative. So I switched them and tried it. I am getting faint spark now but not enough to start.
I tested how much power I have at the coil.With the points closed I have 6.2v. When I open the points I have 12.4 volts. I don’t know why I have 12.4 with them open because I have a resister?
Anyway the tractor will not fire. I am thinking that all I haven’t changed is the cap, rotor, and wires. I am about to change the cap and rotor to see what happens. Anyone got any Ideas? Please be kind I am a newby at this. Ron
