Before I sent it off I would trouble shoot it, the silver metal relay is a double pole single throw relay the other small black ones I would just replace any auto parts store will have them. The other two big relays I would pry the cover off and look for damage on the coils, if you smell something burn you should be able to see it under the covers of the relays. I also would check the reverse polarity diodes. I see a 1000 uf capacitor in the circuit thats to lessen the arc on the contacts of the relay from the inductive load of the solenoid, that might be blow up which will cause a smell.
