Your System Voltage is dropping to 8.5v during cranking. That is VERY bad according to Mercury Marine. With the PCM112 they want no...

I can't edit post #116 When I said. "Any drop above 0.5v is bad. So 0.4 while at full charging is the only good number you have!" I...

I tried to answer all your questions and give you my insight. If I missed anything let me know and I'll try to help.

Funny thing—- maybe because I understand the new systems, I find them easier to diagnose. Especially if it has cats. Another funny...

If it walked out of position, yes. If it spun a little bit, that got rather involved. But I’ve never had to do it, so not 100% sure.

Yes but still helping on the MerCruiser front. i looked up one of your Diacom files to see your MAP readings.👍🏻
