OK that is a standard mains filtering cap. Normally used in the first stages of a Power Supply--which is exactly where it is in this unit. They do give trouble, but is not that common, they and the coil in the picture are in the first line of defence of the psu when the mains is applied to smooth the starting inrush.
Not really, the mains filter caps do not regularly fail, whereas electrolytics do on a regular basis. The problem is usually the hot environment in which they are working. The electrolyte solution (in this case a paste) just dries out over time. Basically electrolytic capacitors are twin sheets of metallic foil separated by the electrolyte paste and rolled into a cylindrical shape with electrodes connected to each metal sheet that are then soldered into the circuit.When you put it like that, is there any way to prevent this kind of damage? Why is it so erratic, happening seemingly independent of mileage or charging patterns?
I really do not think it is actually "planned" obsolescence! There is no planning involved. When these things are first mooted, such as the onboard charger, the prime objectives for the Nissan design team I am sure were:Thank you for taking your time to explain this. I am baffled to understand that cars get wrecked over a dried out paste. No clear boundaries between planned obsolescence and technological boundaries here, but it's about pennies worth of material, indeed.
They can go in all manner of ways. While working on a Barco 3-gun projector system with an intermittent fault in my workshop one day (in 1993), an electrolytic capacitor in the line timebase circuit exploded in my face. Luckily most of it caught me on the right cheek, otherwise I may have lost an eye (or 2). Electrolytics usually just dry out over time as the paste loses moisture. Other capacitors mylar, tantalum and disc ceramics for instance usually fail at the point where the material is internally connected to the terminals.I can hear the coolant circulate on my ZE0 when charging, too. We almost exclusively charge at night - not for the temperature, but for lower electricity prices.
It is my understanding that a capacitor does not go out gradually, more with a poof!. That is my experience from several appliances, without much deep knowledge. I hope you find the cause for your issues, @whereswally606!
That is a big mother of a cap. 60microfarads at 400v ac is a serious bit of kit. I'll bet a new one will cost you an arm and a leg. A log splitter requires a lot of grunt. If you can't find one, go to your local dump and have a look at old 'fridges microwaves and other electrical scrap stuff for one roundabout the same capacity and voltage. It is simply a starting capacitor, and tolerances are fairly wide. Anywhere from 40-80micrfarads will be suitable, but make sure it's at least 400v ac.Unless there's physical movement in the capacitor, allowing for contact/no contact, doesn't that mean they fail abruptly, indeed? I always appreciate your feedback and I'm happy you got away from that exploding one!
The last capacitor I saw fail was on my log splitter. That one certainly let go of life abruptly, smoking a fair bit in the process. Which reminds me; I ought to get a new one before tree felling season arrives.

That's a bit low, might have trouble starting the motor.... try and aim for at least 50microfarads
