Replacing origional 6V coil

[JohnWayne]

what do I get? & where can I pick up an aftermarket local? Don"t I get a 6V coil without internal resistor? NAPA only carries one 6V & it has an internal resistor (part#IC7). My wire feeding my coil off the ignition goes through a resistor before it feeds my coil (I think). Does this mean I can bypass my stock resistor if I go with the NAPA coil? Talk to me all mighty gurus!

Hey John; Is your tractor converted to 12 volt and retained the 6 volt coil? Generally that is why there is a inline resistor, to reduce the voltage. The stock 6 volt system does not use a resistor, at least I can't find one on the diagram. If it's converted you should get a 12 volt coil with internal resistor and do away with the inline resistor.

Not that I know of... I just bought it last year. The guy I bought it from had a 12 V battery in it just to get it to start so he could sell it. So I put in a new 6V (+ to ground)970 cold cranking amps battery. I've checked timing, & compression...I've replaced the points, plugs, rotor, cap, and am wanting to get a new coil, & plug wires (copper or metallic core)as well.

What tractor are you working on? If it was 6-Volt from the factory, and has a "round-can" coil, it did NOT have a "stock" resistor. The PO must have added it while fooling around with 12-Volts.

An IC7 coil does NOT have an internal resistor, nor does it need an EXTERNAL resistor, when used on a 6-Volt system. It is simply a 6-Volt coil wound with the correct size of wire and number of turns to function on a 6-Volt system with no added gadgets.

If you are intending to make the system 12-Volts,
get a NAPA IC-14SB coil, which is a TRUE 12-Volt coil, and needs no external resistor.

Bob.. where do these parts counter guys get off giving such bad info.. like telling the guy that an IC7 had an internal resistor??

no wonder most people don't know anything about electronics past turning on a switch.. it's because the guys that should know a little bit about it give out bad info... grr...

know how much those counter guys get paid? or how much training they recieve?
after almost 4 years fulltime with the company i'm at--8$ an hour, minus benefits (why are they called a benefit if you have to pay for them?). I have had maybe a total of 20 minutes training in those 4 years. Luckily i train myself. as to my coworkers, i'm apalled at how little they need to know and how little desire to learn they need to pass the hiring process.
for me, 4 years of college doesn't seem to help them consider a different pay scale either.

It's great that you go the extra mile and try to educate yourself further. it's a shame that it doesn't equate into monetary rewards.. because it certaintly should. I'd prefer to pay just a hair more for my parts and get them from a place that has knowledgable people, and be assured i was getting the right stuff.. vs buying from a 'walmart' bulk distribuitor and have no real sense that anybody knew anything about the parts they were selling.. even if it was at a slight discount.. etc.
