SEARS AUTOMOTIVE ENGINE ANALYZER Model 161-2161 Made in USA.. Condition is Used. I have no way to test this. But there is nothing about it. That looks as though it would not work. There is no obvious damage to the device. There are no cracks. No brakes. The test leads appear to be intact and slowly functional. Instruction manual is included. Original boxes included. The box is a little beat up, but it is fully intact. The device appears to be in good workable condition. But since I have no way to test this, I am selling this as is. This item includes the resistance unit as well as the shunt as shown in the pictures
