how to test a condenser?
how do you test a condenser to see if it is any good? I have a few laying around that I have no idea if they are any good or not. Had a heater manifold on the car years ago, and we were (or so I recall) blowing condensers out, or so we thought. So had several on hand, but not sure which are 'good' and which might have been the suspect ones. I'm going to go back to the 'original' distributor set-up from my 'modern' rebuild, and see if I notice any difference. Don't have the heater manifold anymore, so not concerned about the condensor any more. And I HATE trying to adjust those modern points! The two halves don't seem to be as 'square' to each other as the original points, either.

Re: how to test a condenser?
I can tell you how we used to test a condenser when I worked in garages. Charge one up by putting it across the high tension on an AC spark plug cleaner/tester and then set it vertical on the workbench, pigtail up in the air. Someone will test it for you shortly.

Tom Wessenberg could help here!
Barry,
Tom Wessenberg has the procedure down and has the test device to do so. If we ask him to post some photos..I think he would do so. TOM...How about it? Good day! Dave in MN |

Re: how to test a condenser?
When I got my car (1969) there was about 20 condensers under the seat, I first checked them with my mulitmeter for shorts, and some baisic operation---the needle on my meter moved, then moved again when i reversed connections --threw out a few that did nothing, then i picked the nicest looking one and put it in --if the car started i ran it ---usually soon after the car would loose power, pop backfire ---then i would change to the next one.
I got very good at changing condensers, and knowing their problems. Even the new condensers didn't seem to last very long for me. Then I bought the A&L "burn out proof" condenser, it is still working 20 years later, and I do have 1 spare now ---somewhere under the seat. I am still using the "original" points. Adjusting "modern" style points most always includes checking/aligning the point contact surfaces first --even with good quality old stock points. I have a dist machine that has a condenser checker, but it is not perfect at predicting that a condenser is good enough to work perfectly in a car, it doesn't have a heater to have the condenser at operating temp. |

I did order a new 'short-proof' condensor from Snyder's today, along with the points, upper-shaft, etc.... Was just wondering of any of these old ones would be any good as a spare, or if I should chuck 'em. thanks again Barry |

Put them in the "in case you break down" box and buy fresh new burn proof ones to use

Re: how to test a condenser?
Along the line of the bench test Richard mentioned. When I was a little kid, my Dad used to do that with the condensors he had laying around. he was a TV/Radio repair man and he got his kicks doing that to me. Made me real cautious around his stuff.
