We have a Simplex MKV and after the unit was put online and water injection was selected, the unit dumped. The <C> core did an automatic reboot and we smelled something burning. After some searching around I found that a relay had burned up on the TCRA card <CD>. The TCDA <CD> also did not have any LED's illuminated. I replaced both cards and although both <R> and <C> go to A7 status, there are still alarms present that deal with the Digital IO.
There are also some alarms on TCCA and TCCB relating to 4-20mA inputs out of limits and these are all on the <C> core.
Here are a few of the alarms I noted, but there are more that are most likely due to the IO not being recognized I'm assuming:
DTBA <CD> Battery system ground fault
DTBA <CD> Batery system LOW DC Volts
DTBA <CD> Battery system AC power charger failure
DTBB <CD> Generator Excessive volts/hertz (24G)
A few others that are curious:
TCD1 <C> Plug J01 Disconnected
TCD1 <C> Plug J02 Disconnected
These are two ribbon cables on the TCDA card that connect to the two TCRA cards in <CD>. Yes, they are connected correctly.
TCD1 <C> Battery Reference Signal Failure (Plug JQ).
All cables are connected correctly.
Is there a common theme here that I'm missing? I'd appreciate any insight to this problem.
Thank you!
