Good evening. I just recently converted our 1950 Farmall H from 6 to 12V. I have followed the instructions from this site as well as had my converted M next to it to follow with and feel I have it wired correctly with the alternator putting out 13+ volts. The issue I am having is the original kill switch was working correctly (on/Off) before the conversion and then after converting the system, it will not kill the engine when pushed in (checked with voltmeter and it has continuity in both states). Thinking this was just a fluke, I replaced the switch with a new. I checked the new switch before installing and it would loose continuity when pushed in like it should. After installing the new switch I started the tractor and the switch worked just like it should. We took the tractor for a drive for about 25 min and when returning to the shop, the switch would not kill the engine again (I pulled the coil wire to kill it). The rest of that day the switch would not shut the engine down. The next day, we moved the tractor again and by habit pushed the switch in to shut off and it worked. Tried it half a dozen more times and worked just as it should. I have tried it since and it seems to still be working correctly. Any thoughts?
I should add this tractor is new to us, so know very little history.
For the conversion I installed the Delco 10Si alt and rewired with diode.
New 12V coil and ballast resistor.
New Ammeter.
Lights are currently not hooked up.
Thanks in advance.
