I have a MC43 with the following blink code 4 red, 2 yellow, 1 yellow, 1 yellow, 1 yellow. What do the 3 yellow blinks at the end mean? This happens intermittently when the module first gets power.

If it's occurring on start up, the likely causes are battery voltage exists on an output before the module powers up or a slow rise in power supply voltage. Possible causes are covered in appendix B of the instruction book.
