Ok so the title of this will immediately make you think it is a RCM or a SKREEM issue. I did too, but here is the story
2005 Convertible Crossfire
- Battery light came on for a few days, stupidly I ignored it as my car seems to have many idiot lights come on randomly then go out so I waited to see if it would go out..... it did, along with all ability to start the car
- had my car towed back to my house. I replaced the battery with a brand new one (old one was completely dead but under warranty)
- contacted DJ Tighe and him and I ran through some tests listed below
- RCM tested and seems ok, both relays close with key in ignition - DJ approved
- we then test the Power Module ( I think ) and we were able to determine that there was power getting to the starter when it was by-pass from the wire (applied 12v directly to the connection)
- we also tested that there was 12V getting to the wire but when connected the starter wont engage
- When I manually closed the relay when applying power the starter did engage but the car would not start.

As it sits I am able to engage the key but the car does not turnover or crank at all. in order to keep trying to turnover I need to turn key to off position then try again still nothing happens, I am not able to turn key and have it simply go to the ON position and try to crank again, the key won't move. I spoke briefly with the MSS team and they had me look inside my trunk for any moisture which I could not see. One reason was that the car at one point seemed to be having an alarm issue. Which is odd as I disconnected the alarm last year but the thought was that it might be alarm related and the car was locked out of starting for some reason. I am pretty sure I unplugged the siren module last year as I totally removed the siren (is there a plug in that I may have missed ?)

I am at a total loss of what to do next.

 

Update. I went out and disconnected the battery for about 20 seconds reconnected and tried to start. on first attempt it did a "half crank" certainly not a full one, turn key to off and tried again got Nothing !! decided to try the procedure again and disconnected battery again, went back to try to start and got nothing, not even a half crank. I find this very odd as there doesn't seem to be any pattern to the process

 

Possibly a short in the alternator,

 

thanks for the input. How would I go about testing for a short in the Alternator ?
