How to test a ignition condenser


Paul Dobbin

Recommended Posts

I now have 6 spares and maybe on the next big tour I'll find out which ones to pitch.   Roadside repairs sometimes need to be repeated!

Thanks for all the technical stuff which was way over my head and is already forgotten,   THERE IS NO EASY WAY TO TEST A CONDENSER!

From memory of very old Dykes manual:

 

Remove both license plates 

/  place a mans handkerchief between them  

/  use string or shoe laces to hang them from rad rod to cowl

/   then place a wire from each plate to positions on distributor ( must  assume exterior mounted condenser )

 

Apparently capitaine reactance was a workable substitute back them.

 

Again from memory.............a long time ago

Interesting. Not saying it's not true, but I've never heard that before.

I just replaced the points and condenser my Buick,it was running but I thought I'd tune it up..Anyway I noticed that the ground wire from the plate to the housing was broken.

   Sounds out dated to me.

    #1   Most States have aluminum license plates now.

    #2   Many states use only one license plate.

     I'll continue to carry a snot rag, just in case.

Can you tell me what tube is used in the tester? Thanks, Jeff
 

 

sorry Jeff I can not,about 2 months after that picture was taken the tester fell off the shelf and was beyond repair 

Thanks for the reply. I have one that either does not work or I am using the wrong tube. I am an antique radio guy so I'll take it apart and see if I can figure it out. My antique car days are long gone, radios are much cheaper.

And this matters how?    Most capacitors are made with aluminum plates!  😁

Then you have a tested good condenser! That's all the test you need to do. 👍👍👍👍

Why wait until you are on the side of the road? Test them now by substitution! You can tell with a short dive if they are trash worthy.

That's a sensible idea but both my early V8's are running great right now.   I'd hate to take a good one out when I know it's good. 

 But I will take a ride in the country tomorrow just for the joy of it.
