#95648 05/21/2006 2:17 PM | Joined: Feb 2006 Posts: 19 Apprentice | | Apprentice Joined: Feb 2006 Posts: 19 | Just wondering if I have to do any modifications or changes to the starter or points,condensor in my 45 chev 2 ton with a 235ci ? I've read alot of the previous posts on the subject, and nobody has really said much about it. I don't really want to change to 12v, but I use the truck as my daily driver and I scattered the comutator on my way home from work this morning. If I have to change the generator I might as well put an alternator on.Any help is greatly appreciated! | | |

They neglected to mention anything about the starter however. | | |

There is, however, a resistor in line with the coil lead. Don't know if this was stock, or added to drop the voltage back to 6 to avoid burning points.
Cheers,

I've heard if you crank it for extended periods you'll burn it up, so I never use it for more than 5 seconds. Since my engine turns right over, no big deal. It's when you are tuning it or first starting it after a rebuild you have to keep it in mind.
As far as the ingition resistor in the coil circuit, or ballast resistor, or voltage drop-they're all the same thing- That is used when you keep the 6v coil, points and condensor. You can upgrade those three things to 12v if you want to, or you can get a '12v in 6 v out' coil, like the ones VW used in the beetle.
