i had repaired greg's icharger by replacing the shunt that burned up. but it appears that the mosfets that connect the shunt to the battery are also shorted and the icharger is now like a dead short on the battery when plugged in.
i saw there were several utube videos and many comments from people who had similar problems so i wanted to form a thread that would document the failure modes for the icharger.
please don't use the thread to yak about how you don't use this or that, or how your hyperion or other type charger doesn't work.
this is for people who have an icharger, they used it and then it failed. i want to document the failure modes by opening them up to look for the components that have failed to see if we can find ways to repair them and prevent them from failing again.
hopefully, by the end of the thread there will enuff info that most can diagnose their icharger failure and know how to repair them.
critical info will include how long you used it, did you ever reverse the battery on the terminals, reversed the JXT plug?
what was the charger engaged in doing when it failed. did it fail immediately when the operation began, after a short time, or longer? smoke or no smoke?
display gone or menu dysfunctional?
did the icharger do anything unusual in the period before it failed, and what was that?
did you already attempt a repair and what did you do and why did you do that? did it work and for how long? did something else fail after that?
i already have some ideas, i also kinda understand the layout of the pcb and the parts so i can walk you through the analysis to help you explain what happened to your icharger.
