  • 12v into 6
  • My Ď46 2n generator died! 6v battery is shot! Itís winter and cold! Looking for a quick fix! Can I do this:
    Can I just put a 12v battery in ? ? ? No lights, so no real draw on the 12v battery other than for starting. Would I need to change to a 12v coil and or change the points, add a resistor or what? I use the tractor so seldom that when done, Iíd just put it on a trickle charger or auto charger. I know the wiring and starter will handle the extra voltage! I have plenty of 12v batteryís!

  • Here ya'll go. I answered this when Jared sent me a private email yesterday so will now spell it out. Still no reply to my questions on how he assumed the GEN was dead. Hence the 6v diagrams. No belt tensioner device? GEN can't charge the battery without proper belt tension. Did he fry the cutout with the 12V BAT if wired wrong? Know the basics before you try to go to another level. I'm NOT nor did I say to not go to 12V.

  • Ok, everyone has who has responded has answered my question, confirming what I thought! Now, answering Timís questions: battery is shot! Will charge, but will not hold that charge overnight, let alone handle a load for more than several cranks! The generator does have a belt tensioner on it! When, tested, (3 wire) I was getting barely 6v on a new charge at the battery, and no voltage at the generator at high rpms. I will retest this once I get all the snow off it and running again, but Iím pretty certain itís done! Also,12v have never been put thru this tractor. The whole reason for my question was because I have several good 12v batteryís that will fit! Just didnít feel like spending $100+ at tractor supply for a 6v battery and possibly more $ for a generator fix! Hence my idea of a 12v battery and added resistor to at least git er goin so I can reevaluate in the Spring time. The engine is tired, but does what I need it to do! It will never get a rebuild, in my lifetime anyway, so perhaps a12v conversion is in the near future!
    Thanks All!

  • As I stated below, it's your tractor, your time and money, and you can do whatever you what with it. I'm giving you the pros and cons. You will need more than just a 12V battery to make the switch over. More importantly is the WIRING on whichever setup you use. Your trusty local starter/shop will bench test a battery for free and also test and rebuild your GEN and STARTER MOTOR as well. Forget the starter - not the issue now. How did you have the GEN tested? Avoid TSC at all costs. Low budget products ten to be inferior quality. poor life spans, and I advise to go with a good brand -DEKA, INTERSTATE, DURACELL, or EXIDE. Starter Shop guy can test all your batteries so if you have a good 12V, Going to need to spring for an alternator and new wiring and cables if you go to 12V or rebuild GEN if it needs it so it's inevitable you are going to have to spend some money if you want to do this right. It's obvious you want to switch over to 12V so do it but do it right. Take shortcuts and you will end up with more issues. I'll buy your OEM GEN and Cutout as I mentioned.

  • If you swap in one of those batteries and a ballast resistor you will be halfway to membership in the 12v club😉

  • Re: 12v into 6
  • To directly answer your question -- Yes you could add a resistor in the coil line to drop 6 volts, install your 12 volt battery and drive away.

    I prefer to keep them as designed but that was not your question.

    Good Luck,

  • Re: 12v into 6
  • Come on guys, he said he had a 12 v battery.
    The resistor is less than 10 bucks.

    No brainer.

    And no Tim, he doesn't need 2 dozen pictures to answer the question he asked.

  • Re: 12v into 6
  • Nobody said he didn't have a 12V battery OZ. YOU may not need pictures but he and many others do. It is apparent he isn't familiar with the 6V/POS GRN system. I merely pointed out these facts. He's asking about a resistor but doesn't say if he means the OEM Ballast Resistor or the 1-OHM resistor required to use with a 6V coil when doing a 12V switch over job. I replied to his private email with instructions for a 12V job. He still doesn't say if he has the Ballast Resistor and my pictures will surely help especially if guys don't invest in the ESSENTIAL MANUALS.

  • Re: 12v into 6
  • OK - 1st question is: How do you know the GEN is dead? Did you test it? Your trickle charger may have overcharged/fried the battery. You need a float charger like the DELTRAN BATTRERY TENDER JR. Did you test the battery under load? Do you have a fan belt tensioning device on the GEN? Next- is it the OEM GEN? Is the wiring correct for this 6V/POS GRN system? All 9N/2N GEN's from s/n 12500 were the same basically: 1-Wire/3-Brush 'A' Type Design, 11 AMP, with belt tensioner AND used the roundcan cutout circuit, 1-Wire Starter Motor w/NO SOLENOID, and also the front mount distributor and OEM Ballast Resistor. Battery should be 6V GRP 1 AG type, cables thick 6V Gauge 00. OEM components meant to be rebuilt over and over. I rebuild GENs, STARTERs, DISTs, CARBS, and more. Email is open. If it won't start now with 6V what makes you think with 12V? You are making assumptions and guesses. Rookie mistake #1. There is more to true root cause problem solving and guessing isn't one. Got your ESSENTIAL MANUIALS? Start there with wiring. I have an OEM 2N GEN all rebuilt to spec and ready to go complete with belt tensioner. Email is open.

  • Re: 12v into 6
  • Figure the cost of a new 12v coil ( $30) and a 12v battery ( $70) . Then figure the indirect cost have always having to charge the battery.

    Now compare that cost to having your 6v generator rebuilt ( $85 around here) and a new 6v battery ( $80)

    So, fix it: $165

    Jury-rig it: $100

    Is it worth $65 to you to always have to use a battery charger?
