Professional Tinkering 6 to 12 volt

Posted by Kevin Westling on January 19, 2004 at 07:27:49 from (66.82.9.54):

I have been reading several of the posts and have even printed the diagram for converting 6 volt to 12 volt. My Super C has already been converted to 12V but I recently had to replace the alternator and battery. The battery never charged properly, but I have found out from the info on this site that it has been wired differently. I will use the diagram on this site(12 Volt Alternator Conversion Schematic for Farmall Super M http://www.ytmag.com/articles/artint195.htm)
for wiring but I have some questions:

1. What is the purpose for the warning light that is inline from the ignition switch to the number 1 terminal on the 10SI alternator?

2. I did not find a ballast resistor inline to the coil(should I assume it is a 12V because at one time it ran and started fine with this setup) and how do I tell if it is a 12 volt?) Assuming the ballast resistor is used to decrease the current to the 6V coil, would it harm the coil if one isn't used or can you replace the coil with a 12V and don't use the resistor?

3. I had to replace my ammeter. Is it OK to go with a 12V replacement?

4. And the contacts on my starter switch are very worn and barely make contact when the switch is fully depressed. I cleaned them well and am getting it to turn for now. I'm trying to not have to replace it. Has anyone ever modified the copper contact end on the switch by building it up with a conductive material? I was thinking about drilling small holes on the end of the switch contact and putting in a couple small screws to increase the reach to the contact side of the starter? Any thoughts?

This site has bee an excellent resource for Professional Tinkering. And when a problem persists on my tractor, I can always count on you guys to help me out. Maybe someday I will take the reins and off my advice. I am just glad I'm not 20 any more because with my stupid young will I probably wouldn't even have a tractor that runs at all. I can get quite confused and frustrated. But now i just step back, grab a beer, and work on something else until the next possibility comes to mind to try and fix my problem.

Keep up the great work posting solutions! So many of us take so much pride in our work and we just need that little bit of advice form the veterans.

Thanks. Kevin
