Alright, right now before I try to work on any another equipment I feel that it is more important to get my VTVM working. The VTVM is an RCA WV-98A. The battery that was in it leaked and corrosion occured on some of the compontents. What I have done so far is taken a toothbrush with a little bit of warm water with dishsoap in it and burshed off most of the corrosion. The next thing I did was use de-ox-id contact cleaner and applied it to all of the switches and vitial components. After that I replaced all of the capactiors in it, except for the electrolyitc cap (it seemed to be in good condidtion) and a cap that was located on the function switch. This cap was rated 6uf to 30uf, i'm not sure what kind of cap this is. It looks like a paper cap. After that I applied power to the VTVM and tried taking some test measurements.
- Problems that occurred were when the VTVM was set in the lower ranges (1.5V and 15V) the needle moved all the way to the right indicating voltages but I wasn't applying voltages at the time. The Zero control did not help to move the needle over either. Nor did adjusting some of the resistors in the VTVM. I am kind of lost now on what I should do to fix this.
