[QUOTE="richg99, post: 429402, member: 4376"] Is the voltage reading from the fish finder only? Did you test the output with a separate voltmeter? A 12 volt battery won't put out more than 12 volts. If you get that reading while the engine is running, you may be seeing the output of the engine's own alternator. Even that shouldn't be 16 volts. If you are just seeing the erroneous voltage reading on the fish finder, and a separate voltmeter shows 12 volts with the engine turned off.. the fish finder is faulty. I wouldn't worry about it. You can buy a separate permanent voltmeter for under 10.00 Richg99 [/QUOTE]
