Volvo MD2040C ignition switch
I am hoping for help from the many knowledgeable folks on this board.
My Volvo MD2040C has a keyed ignition switch for starting, similar to an automobile. If you turn the key to the right it resets, to start the engine you turn the key halfway to the left and this activates the glowplugs. You see a light with the glowplug icon. Then you hold it there for ten seconds and continue turning the key to activate the starter.
The other day, returning from a sail, I tried to start the engine and got nothing, no sound, no click, no lit up glowplug icon. I was unable to start the engine. Batteries are fully charged. The eingine usually starts right up.
I am thinking I have to replace the ignition switch. The only reason I have not done this yet is the cost. $320 for the switch (ouch).
Before I do this does anyone have any ideas what might be going on, am I missing something? When the engine is shut off via the kill switch there is usually an alarm buzzer that goes off till the key is put back in the up and down position. This is not happening anymore.
Another odd thing is that this failure to start happens intermittently. Usually it starts when I leave the dock, I shut down to sail, and then fails to start when I am about to return to port.
Any ideas? Is replacing the ignition switch the first thing to try?
Thanks in advance.
