12 V electrical system diagnos-cs
What is the problem ?
Engine star3ng Domes3c power
If the engine is turning over but not star3ng try using the emergency link switch to bring the house baceries into the circuit .
Is the appliance switched on at the main switch board .
If there is no noise then the engine bacery is likely to be switched off
Does it need turning on at the appliance i . e . Lights , fan , stereo or GPS
If the bacery voltage is below 12v on the gauge in the boat run the engine at a minimum of 1200rpm to charge for an hour . Using the invertor will quickly drain the baceries so you may need to consider having the engine running whilst using the invertor .
Is the correct switch definitely on ? If yes then check bacery voltage is over 12V or it will not be able to run the systems .
