Incorrect polarity
Long story short:
Boosted my car. Friend reversed polarity on booster cables.
Care won't start. There was smoke coming from the ecu which I've confirmed is burnt. I also burnt a fuseable link.
Is there anything else that might have been destroyed that I should look at.
Might be worth adding that the engine doesn't even try to turn over. Just a clunk sound and a drop in voltage.
Also, the warning lights are all on, regardless if the key is in the ignition.

the jump box didn't have the polarity sensor on the pos clamp?
think you will have to see if the starter jumps , test the starter relay , on the just clicks
after you find a ECU... that is.
I.ve worked places where the porter is a no nothing teen that does this
but then the service manager asked me where the valves in the engine were.
