Hi, Is there any particular type of condenser I should use on the 6 volt coil?I have a handfull of different ones,some have different numbers on them?

A condenser controls the direction of erosion on the points. Due to the short trips of driving we do with these older cars, it really doesn't make much difference as to the value of the condensers. If you see excessive transfer of material from one point to the other, change the value of the condenser and check the action. ![devil devil](/images/graemlins/default/devil.gif)

Hello all, empirical values shows something between 0,20 microfarad and 0,26 microfarad mostly 0,22 µF for the ignition capacitor of a combustion engine. Condensor erosion | capacity - variability Is there anyone who can confirm what's shown in the above graphic ? THX have a nice day !

Oh, one direct match - not so bad but I asked about someone's experience about the changing peaks on the contact (+)(-) if you run with an low or high capacity condenser ? Have a nice time.

That is an exact description, or visual, of what happens. Don't know how it could be depicted in a better way. ![devil devil](/images/graemlins/default/devil.gif)

Hi, A - As we have already a tolerance capacity of something like (+20 / -10) percent (par value) it would be of interest, what value step do you need to change the peak location from (+)to(-) or vice versa ? B - Good or bad - it's not so easy ! Lets have a look on page 3 at the table #3 ! Very tricky the old coil paper condensers, especially #10 and #5 if they run on an higher temperature. You will measure hardly a change in capacity and isolation resistance at room temperature (20°C), but a very significant change in capacity and resistance at 100° Celsius ( boiling point of water ) C - Today's first choice > Metallized Polyester Capacitor | Polyethylene-terephthalate (PET) Reliability: Operational life > 300000 hours at +85°C (+125°C permitted for 1000 hours max. distributed over the entire operating life) Have a nice day !

Condensers are the same for 6V and 12 V
