??!! Burned Out 2 SMEC's In 10 Miles !!??

[2.216VTurbo]

WOOT! RedBox lives again! Pin #5 on the 60 way connector says 'signal ground' it wasn't grounding so we added the SIXTH chassis ground I've installed since this issue started and tapped it into the #5 pin black/white stripe wire and it fired right up

#5 blk/wht intersects with the blk/wht wire that goes to the diagnostic port, we just took a length of wire, added a lug ring (to chassis ground) and a male spade and stuck that in the diagnostic port. I know this is kinda temporary but for the real fix should I just tap the chassis ground into the blk/wht #5 a few inches back from the 60 pin connector or??

I'd have to trace the wire and fine the issue in the harness

Good, now you can tear it apart and fix this

^Yeah, but I *KNOW* how to do that stuff the electrical is greek to me I have a very nice big valve swirl head I'm just gonna swap on. It will be a 1 day R&R if there are no surprises

Put about 15 miles on RedBox today, smokey!

Glad you got it figured out! Electrical can be intimidating, but gets easier and easier with practice. Enjoy the car a bit!

What happened to that valve guide?

And, glad to hear you narrowed in on the problem.
Can you see everywhere that blk/wht wire goes to?

It's glad to hear it's been resolved.

It dropped lol, I would guess that the press fit in the head wasn't right.

That circuit is very universally applied across 2.2/2.5 and comparing a couple different manuals they all show it going to the diagnostic plug, splicing off and through a connector and to another splice before ending at the negative battery terminal. Sounds like somewhere in that chain it is broken. The ultrasonically welded splices if not sealed with glue lined heat shrink turn into solid green chunks of crap even under wrapped on tape. One of many reasons why 418 is getting a fresh, zero time new harness under the hood.

I think some guy mention the scanner going nuts was a good clue a page or two back..

Yeah all hindsight is 20/20 right

[ajakeski]

I'm still waiting to see the intercooler and plumbing...

[chromguy]

So it appears that none of the SMEC are burnt out! Good stuff...
