This circuit is from a stinger auto voltmeter, I believe the burnt out smds (the two black components are blown) and the bigger one is actually cracked. Could someone tell wat these components are so I can get them at the parts store and see if replacing them may bring back my voltmeter to life. The bigger smd which is the cracked one has B055 imprinted on it and has four pins , hope this can help in someway. thanks
