We had the battery tested and charged today and still nothing. Lights come on, it makes some clicking noises and that's it. Oh, and the traction control light flashes red which we think might be a security alert but not positive.

We've tried
Jumping the starter through the relay and on it directly and it seems to work fine
We've checked every fuse twice
Cleaned the direct battery grounds, but not any others around the engine bay
Moved relays to see if one happened to be bad

Here are the following error codes we are generating. Not exactly an expert when it comes to working on cars but any assistance would help!

P1638
P1646
P1603
P1797

Welcome to the forums.

I am guessing you are friends with Lemons Racer as he already has two posts on here about this issue he is having with your race car. If you aren't associated with him, this would be a HUGE coincidence as he has the same exact codes as you.

 

Yes didn't realize he posted on here. My bad!

 

LOL, we're next door neighbors but the team has grown to 15 so there is bound to be some crossover. I am learning a lot about the electrical system of the car though. As long as it's not the ecu I feel like we'll find a solution. We race Saturday through Sunday and Saturday night we had a ton of rain. I'm wondering at this point if water possibly snuck in? Alfa, don't be surprised if someone else comments on here from our team. It is the best Jag forum out there!

 

The more the merrier! Yes, this site IS the best forum around. Hope you get everything sorted out soon. Must be one specific thing if it was running fine when you put it away last. Hope it turns out to be something relatively simple. Let us know how it goes.
