You can leave the IC in place, use 2K Ohm scale or auto range, I expect the short circuit to be at the VCC pin.

you will need to put it in and atleast ground it with 1 screw. the 1000mf caps might let it work but they should be replaced with low esr and same mf as the original ones which are 35v 1500mf i believe.

hi

for testing resistors the best way to get good results is when you take out of the circuit or you remove one end of it out of the circuit
for the ic you do it on circuit when the power is on and if the vcc is present BE CAREFULL
