It would be interesting to know what the truck EEC-V PCMs look like inside.

Back to the selection of the proper replacement caps, do you happen to have the part#'s for the ones you used Guy? Even if I limit my search to Panasonic, I'm finding multiple choices of caps with the same exact specs. The ones I've tentatively selected are from the NHG series as follows...

10UF 63V 105c NHG Series PANASONIC ECA-1JHG100

47UF 25V 105c NHG Series Panasonic ECA-1EHG470

Here's a link to the spec sheet...

An interesting note on this series of caps, which may mean something, or nothing at all.... Panasonic doesn't even offer the 47uF in 10V or 16V; the lowest voltage offered is 25. Perhaps they were problematic in the lower voltage spec parts and thus no longer offered???


I purchased these from Digi-Key @ DigiKey Electronics - Electronic Components Distributor
47UF 25V $.33 ea Part # P14411-ND
10UF 63V $.30 ea Part # P13467-ND

From my research as well as speaking directly to Panasonic Techs , these caps will operate at specified values well below 6.3V , so not sure about the specs you have there , but those are a different type as well , so that may be the difference .
