RE: voltmeter problems
I think I would be very glad if I could say if mine lasts a full 8 years. Mine is around 2-3 yeqars old and works just fine. Its just that I worked avionics for 31 years and I am used to a much higher quality voltmeter. A fluke or a simpson are built to last. Maybe I am wrong but my Hobbico looks and feels like it was made to be replaced fairly soon. All that being said K-Bob is right. Often times its just a lead problem. Can you take your banana leads apart and check the connections? They may have worn thin and need re-soldering.
