hi guys yesterday when i drive to home i found my batt volt going to 9 then i checked my alternator but is good but i changed nothing happen same problem no charge now i jamber my alternator to fuse box to charge without pcm now when the engine is cold my voltmeter going to 19v
i turned off and start again to become 14v and i got another problem with the enging cracking and i got misfire in cylinder 1 and 5 and ignition coil circute p0352
i open my pcm and fount this
its cherokee 2000 classic
i am about to change my pcm if i change it will that burn happen to pcm again
I just replaced the pcm in my Excursion. I ended up buying one from O'reily's. I was going to use autoecms until I saw their amazon ratings and emailed them. Here is the email:
Quote: Hello,
My pcm (2000 ford Excursion 6.8L V10) is a YC3F-12A650-AMD but according to Ford PCM YC3F-12A650-AMD information, there is an updated version - YU7A-12A650-BYA.
Do I order the same number as mine or the "updated" version? Also, I noticed you sell on Amazon but did not see the core charge that is listed on your website. Is there a core charge if I buy through Amazon?
Thanks,
Robert

Hello again,
Is the price better wholesale? I’m not sure what that means. The Amazon price is $395 +$15 for shipping. Your website shows $395 + $100 core + shipping. Do you have the capability to test the pcm’s at your shop? I couldn’t find any warranty info.
Thanks again,
Robert

WHOLESALE OFFERS A $100 CORE REFUND WHICH MAKES THE TOTAL PRICE $100 LESS THAN RETAIL PRICING AFTER THE CORE IS RETURNED
THANK YOU

When I tried to order through the website, the total was going to be $495 plus shipping. Is that a mistake? If not, then it would equal the $395 but without the core to deal with. Do you see where the confusion is? Amazon is 395 without core and the website is 495 with the core and 395 after a refund. Is it supposed to be $295 after the core refund?
Well, the price on Amazon yesterday, and at the start of this email communication, was $395. I will assume you changed it in lieu of our conversation. That is an under handed thing to do and I now understand why your rating on Amazon is so low. I’m not sure if you find humor in conducting business this way, but you are wrong in my book. In addition, typing in all caps is annoying.
i dont know when the pcm burned coz i got misfire and ignition coil problem after jamber my alternator engine now knock knock knock
now i shud change the pcm
but i need to check wires before change the pcm
i dont know why mopar make charge from pcm...... to burn pcm i think
The voltage regulator is located in the PCM, since 1991, so it has proven to be a reliable system. You had a problem with the charging system, and failed to fix it in time, putting excessive loads on the regulator circuitry.
