BFL, the diode bridge is in series with the capacitors.
BTW, I was going to mention this since we are talking about inrush current and a possibly faulty converter. Do you have or know about a dim-bulb tester? It might be a good tool to use in a case like this where components are failing. You can build one for less than $10 and has saved my bacon a couple of times. I'll try to fond a link to a well made one.
Not a clue, sorry. I can understand there might be other components causing my problem , except it has happened with two different 100ampers. Also they work just fine with cold starts even with broken thermistors as long as not too badly broken it seems. This makes me think the other components are ok.
The 100amper with the broken MS35-5R025 thermistor that would not even start, fired right up with a new thermistor (it has an SL32-5R020 at the moment--might have to change that, we'll see) so I don't think the rest of it is damaged.
There remains the issue that if I only do cold starts, the thermistor will eventually fail from accumulated overheating from:
-running steady state with too high an R value, or
-too many inrush hits where it holds ok for a while then can't take any more
This is a really good discussion, with differing opinions, so I am now well armed to ask questions of tech support. They are working on a reply, so that might clear things up--or not! :)
