Default Another Condenser Question

Today as I was installing my fourth condenser in a year in my 1934 V-8, a question came to mind. What would happen if you installed 2 condensers in parallel? Would they interfere with, or provide backup for each other in the event of failure? Would you have the mfd value of both added together? Or, would the engine even run? This time I went with a remotely mounted NAPA RR175 in hopes of having better, longer lasting results. I am tired of buying condensers that don't last.

Adding two caps in parallel gives you twice the value.
Since value is choosen for optimal performance...twice isnt in the perfect range...

I agree , good answer.....
We have had good luck with the rr175 thats what we use in our chevy conversion unit. Over 1000 units maybe had three bad ones.....
One of the bad ones a customers wife said the distributor was noisy , she could hear the points arcing when it ran......The condensor had went to a very low capacity when tested .....Couldnt slip in the house with her i guess.....

Just my 2-cents worth... from my 35+ years of working on these and testing many coils and condensers on my Ford Heyer units... I know that some have said that the old Ford condensers aren't any good but I will tell you I have experienced the complete opposite. Most of the time the NORS ( New Old replacement stock) units are bad even new out of the box... but the original Ford even used and dirty have at least an 85% plus chance of being good. NOS ones in the box are almost 95 +% chance of good. Any electrical device no matter how new or old can fail....

I'll take a NOS Ford anyday... I agree with post #2 as well

I have several Ford~Heyer units and to properly test condensers they have to be heated to about 180 degrees. They all look good cold. Same with coils. G.M.
