Dyna Starter

[Ronbye]

My Rival 32 has a Volvo MD2B Diesal engine which is equipped with a Dyna Starter (some people refer to them as a starter-generator). I have had no trouble with this dyna starter but have noticed for the first time that it gets very hot when in operation. As there is no unusal noises coming from it, I.E. bad bearings etc., I am not sure how hot these things should get.
Does anyone know if this is normal?

Hi,
I have an MD6A also with a dynastarter and generator combo unit.
It does get quite hot also. I bought the boat last season so I don't know if this is normal.

But.. I have my belts to the dynastarter very loose because if it is, infact the bearings that are getting old, the lighter load on them will prolong it's life.

I plan to get the thing opened at some point and have the bearings changed out.

ps. generator is not connected.

pps. also, i just remembered. I did talk to a starter guy that says if the thing is conected to the circuit wrong, it may be producing heat electrically by working against itself.... developing..
