I mistakenly hooked by battery cables up backwards on my Cummins marine diesel engine and 1 particular component on the alarm board of the dash panel started smoking....I disconnected a wire ( purple wire to right of component) to that board and it stopped smoking and am still using the engine but now have no audible alarm for over heat and low oil. The alarm board i's over 500 dollars to replace. Can mine be repaired by removing and resoldering in the thing that is smoking?
