Are you sure the condenser is good? Just because it's new, doesn't guarantee it's good.
What's your coil voltage? Assuming the condenser is good, too much voltage to the coil primary could cause arcing at the points. Has the resistance wire been replaced with regular copper wire? |

Could use old school Mopar resister on the wire to the coil like this.

Good points so far:
Lacking resistance wire, as in it's been replaced by an ordinary copper wire, incorrect coil, however, that's most likely to be the case on cars that use no resistance wire or ballast, Bad condensor - that's really honestly rare, but can happen, unless you're already on the 2nd one and it's still doing the same, OR - and I say this as it's interesting comment about alternator - how's the voltage? Is the regulator bad, causing the alternator to die, and now causing an over-voltage condition? Check the voltage of the battery with car not running after having headlights on for 30 seconds, then check it again with car running about 1,000 RPM or so. If it's over about 14.7v with a moderate under-hood temp, you have a problem. The voltage will vary with ambient temp so if the air temp near the regulator is under 50 (f) then you may have say 15v or so normally. But if the air near the battery/regulator is warmer, then 14.7 is as high as you should see. Check for that resistance wire in the line from ignition switch to coil, check the condensor, check the voltage output of the alternator -

ha ha ha ha !!!!!!!!!!!!!!!!  thats great!!! sum really great "points" ,(get IT) i put a new set of points + condensor in ....both made in "usa" stuff , guess wot ...............................points burnt to a crips withibn about 30minutes  rotten mongrel!!! .......car started mising etc.....just like ol times but not as bad, i tested the current before around 12.5 vilts ...time to get serious... again, i dont think my 66 classic hardtop has a "resistor" as canot locate one /not sure if the 66 cars car with one ????? (this is one of your cars LHD , so dont blame the aussies's )..........i think i gunna call one of my auto electrical mates to suss it out ...im thinkin it something very weird .......bloody ramblers ps ..my aussie built RHD 64 classic NEVER gives me this much greif in the 20yrs i have owned it  |

Sounds like someone removed the resistor wire, re-wired the coil OR the solenoid "I" terminal is jammed against the plunger. Found that on a couple of mine in the past, but fairly rare. Unplug the I terminal and it had voltage even with the car shut off.

The v8s use a resitence wire in the wire harness , the 6cyl the resister is built into the coil . Most after market coils do not have the built in resister. Check the voltage in and voltage out , 12 in 6to8 out. If 12 out add a external resister .

BLOODY RIPPA MATE!!!! well this advice made me go look at the coil, and the Original coil was replaced before i bought it with a bosch coil without a restistor , i then replaced it with a gt40 coil , again without a resistor , tonight i replaced that with a elchin gx80 coil WITH A BUILT IN RESISTOR , the car runs perfect and i have not burnt out the points in 30minutes as per the last 4 sets .....mate i have been searching for this problem for weeks , and 2nights ago i was convinced it was a dude lifter and was just about to pull the head off .... YES THERE IS A RAMBLER GOD.....AMEN!!!!  bloody good ramblers ps ...thanks to all the guys that answered/helped me out |
