Just thought I would get a little input here before I go back to California
to work on my little ship. I have a Yanmar
4JH2, 44hp. diesel
in my Ingrid 38. When I first installed it, everthing worked just peachy-keen. Later the tach began to fluctuate intermittently along with the gages (temp&oil). Now the tach is dead completely and the gages work intermittently. My batteries are very flat. I'm doing a total refit
, so the batteries will be the last thing to go in. To start the engine
every once in a while, I turn on the battery charger
and charge what life I can into the dead batteries. They do not hold a charge for long but it is enough to fire up the Yanny. I know the tach works off a trigger off of the flywhell but my question is. Does the bad batteries have something to do with all this? Like not enough juice to build a field in the alternator
Any input would be appreciated.
