Multimeter stopped displaying after replacing battery

[zillah]

Dear All

I have got a spare multi meter (secondary one) that was sitting on shelf for couple of years and today I switched one to check if battery is dead or not and it was displaying reading on LCD,,,,but I thought it is good idea to replace battery although it wasn't dead to avoid any feature leaking

I replaced old battery with 2 new batteries (yes new one and I checked voltage of it by using my primary fluke mutilimeter and their reading were 9.6V) but unfortunately multimeter not displaying anything on its LCD.

1-Battery terminal fit tightly on the snap connector and the snap connector is clean
2-I checked the continuity between the connector end and the soldered end on PCB for both red and black wires they were good
3-But when I did the reading on the soldered end of red and black wires was showing 1.54 V !!!! supposed to be same v as battery,,,,,,Do I need to remove the solder and solder it again ?

Have you tried testing the voltage of the battery again?

Yes and it is 9.6V

Yes.

When you said : Solder short ,,,,what you meant by short ?

Disconnect the battery and check if there is continuity between those two solder joints.
There should not be!.

I disconnect the battery and I did check continuity on soldering ends no continuity and then checked at the snap connector end also no continuity

Ok, so no short then.
But obviously very high resistance for 9.6V at battery snap connector and 1.54V at the PCB solder joints.
Are the PCB pads ok?.
I’d be inclined to remove the wires and clean the area while checking the pads.

Agree

Looks okay

I will do that no other choice
