my 2010 cougar ftd has had depth finder voltage issues all this time.i finally found the culprit.full battery voltage is present at both connectors unplugged but yet when connected voltage shows 3 to 4 volts low on display.i show continuity between power and ground of 3 to 4 ohms resistance with the master switch off. can someone please tell me where they have these 2 tapped in to the wrong circuit and why? im thinking the rear junction block or alarm system.dont want to run new wires if not needed.thanks
