Hi,
I need your help urgently
I have installed recently an old fuel pump for my car I do not know its make but it has a a small board with "transistor I suppose number D73" beside 2 diodes and 3 resistors. The mechanic committed a fault and reversed power polarity resulted in blowing the D73 and the diodes, how can I go about fixing the problem , and I can not find a substitute for the D73
