My sailboat has a Universal M3-20B diesel. Just recently it has been hard to start. When i press and hold the button to warm the glow plugs the gauges on the control panel are showing power.
After the 10 second warm up procedure I press the start button whilst still holding down the warm up button (The correct starting procedure on this engine). As soon as i press the start button all gauges (Amps etc) drop to zero - dead. When i release the starter button the gauges come back to show current. The batteries are good.
After several repeats the engine starts and once warm it is ok but I'm worried in case this gets worse or i need to start a cold engine in a hurry.
Any suggestions are welcome.
Thanks,
Mike
