New condensor for 12 volt conversion

I'm converting my 51 to 12 volt and have most of the parts. Do I need to change my condenser? Technician at Macks Trucks says I don't. I'm not so sure about the advice given. Let me know if my concerns are warranted. Thanks.

I've converted a few Ford tractors from six to twelve volts and have never worried about points or condenser. Never had any early failures of the points. However, your coil polarity should be changed.

I'm adding a ballast, and will install a 12 v ignition. I just want to be safe and not fry anything I have to go back and pay for.

If the condenser is an electrolytic type (and I think they are) they are polarity sensitive. Couldn't hurt to swap to a 12v type. Why not go "all the way" and go to electronic ignition?!

mbarrad, You're new here. We need to see pics of your truck. It's a "requirement".

Lol! If I can get her started this weekend, I'll move her out of the garage and take some pics. She's a beautiful girl!

Hello and welcome to the forum. I'm still looking for those pics!!!

Condensors are one of those products that break down over time. For the cost, I'd throw a new one in there.

New condensors are a crap shoot with so much coming off-shore. The old ones are more reliable - run yours until it fails, then keep a spare or two in the glovebox.

Ross, I'm not sure about that - I run my original on 12V neg grnd and have for 10+ years with no hiccups from the polarity change.

As far as voltage goes, your inline ceramic resistor drops the voltage to the same as the original 6V system. The points only see about 4.5V

been building magnetos and dist for 40 yr and never changed pts or cond for 6 to 12v.
if you don't want to use resistor, buy a 12v coil with internal resistor. it will say on case
-no external resistor required.
