the amount of work we take from these UNI-T units i think it serves its purpose, recently assembled a digital thermometer with LCD and i was having small **** bits laying on my work bench and i tested at least 4 different resistances and it showed it accurately, will work for kinda projects that is undertaken with this equipment.
regarding the new grip i am also thinking of getting a used one, i'll simply remove the two thin wires connectors from the burnt grip and insert them into the new one as they show no sign of damage and will joint the other two. and there is some other grip or connection hidden behind the carpet which is un accessible as harness is routed behind the blower motor and evaporator assembly because the color code of wires in 4 pin connector is different then one that goes into the blower, any ways got a grip that is burnt and it needs replacement.
regarding the capacitor, have no idea and i dont see any capacitor in civic schematic as well, well even then i can confirm that my city does not implement any capacitor unless its hidden behind the evaporator but its not a place to stick a capacitor in. and i didnt get how a capacitor will cut down noise, mazeed tafseelat biyan kejiye iss bare mein!!!!!!
