FICM is it bad?

[MaydayMay]

04 6.0 with the 4 pin
Ok! did a lot of searching and reading so i tested my ficm and its reading 20V drops to 19V and then to 47V and holds there. With all the reading i could not find if this was normal, or as soon as you hit the key it should be reading 45 or higher. If its bad should i seen it to swamps or to some other comp.? how long does the do it yourself repair been lasting people? Is it better to just send it off? What you all think.....Thanks

The FICMs bad...not sure about the repairs...just buy a new one so u know its good and warranted.

It's bad, it should hold around 48 with key on and when cranking. I ordered mine from swamp's and then sent my old one to them and got the core charge back.

I'd recommend doing the resistor re-solder repair! The resistors in mine looked like they barely had any solder holding them on, and one of them was actually loose when I touched it. You can find an awesome writeup in the 6.0 tech section.

What do you mean by cranking? i did not do that, was i to be cranking the truck over and checking the volts too?

Here's some reading material for you.

DON'T BUY NEW! I have no solder experience and was able to repair in less than an hour! Dealer in my town wanted 1400 to replace, soldering gun will run you 30 bucks tops! The write-up in the tech section walks you right through it! PM me if you have questions

Yeah, you want to get a voltage reading with the key on and while cranking. I had a friend crank the motor over while I tested the pins.
