I was told by the user manual and by users that if you have a solid red fault light then the CPU is shot and it needs to be repaired
I bought a L35e and was flashing it up to V19, a few minutes into the flash it faulted, see below for the code from the flash.
So I restarted the CPU and got the solid red fault, so I removed the battery and shorted the positive to the negative for a few minutes (this takes about 10 min) tried short time but it did not help
This is the 3rd solid red light that it has cleared, I don't think it will work for all solid red faults I think the solid red comes from not doing a full boot cycle so I am sure there are several reasons this may happen, I think this one was just at a bad spot in the boot cycle and could not start from the beginning until the capacitors were drained and then it would start over, the other two I received they were red (not flashing) from the start so not sure what happened to them when they faulted in the first place,they were also L32e's.
Just thought I would pass on the info and may save some people a few bucks or some time, I don't think Rockwell recommends this as a practice but if you have a faulted/failed CPU you need to try something and this may work
The second flash to this CPU went great!
