Tried a $30 multimeter from Harbor Freight on a Cessna 172 and it gave me a ghost voltage reading
Last Tuesday I was troubleshooting a intermittent nav light issue on a 172. Grabbed my cheap meter because my Fluke was in the shop. It read 12 volts at the connector so I thought the wire was good. Turned out to be a bad ground and the meter was picking up phantom voltage. Chased my tail for 2 hours then swapped in a Fluke and saw 4 volts. That cheap piece of crap nearly cost me a whole afternoon. Has anyone else had a cheap meter mess with your diagnosis?
