You didn't mention what the EC2 EGTs were reading but they should read 0 or= 32 if jumpered correctly.   They should blink only if out of lim= its (32 is not out of default limits) but check what the High & low lim= its are and set them above (high limit)  & below (low limit) whatever the EGTs are reading and they should stop blinking. <= br>
