Yanmar 2QM20H - now what have I done?
Hi all. I have an Irwin Citation 34 with Yanmar 2QM20H engine.
This is a "Now what have I done" question.
What I did:
Today, I went out and replaced the electric bilge pump hose from the
pump, through the engine room to the thru hull port read side. I took
the old one out, put a new one in - same route.
It worked well - I am really please and the old hose REALLY REALLY STUNK!
OK - it was hot as blazes (34C - 93F and sunny - very little breeze). I
was looking forward to going out to the mooring and going swimming.
Turned the key - no warning lights, no squeal from the buzzer - no
results when pushing the start button.
OK - I know I have done something - its just an engine, I have knocked
off a wire or something. If you have an IC34 - you know the amount of
room where I was running the hose. I did a bunch of eye ball trouble
shooting and finally I took the cover off the little fuse box on the
port back area of the engine - just aft of the aft injector, and the 20A
fuse was blown. Fortunately, Irwin made sure there was a spare fuse in
the box lid. I put the new fuse in, turned the key - buzz, lights and
the engine started. The tach did not work and within minutes the
alternator light came on. Knowing you don't need electricity to run a
diesel - just need it to start it, I turned off all radios etc, put the
batteries on one battery and motored to the mooring. I had my swim and
a beer, felt better, and looked at the fuse - sure enough - blown again.
What have I shorted out? OK - all you armchair mechanics - where do I
start when I get to the boat tomorrow afternoon to start trouble
shooting. And yes - I am going to buy a box of fuses.
