Is this the Westerbeke 7.0 BCGB generator? That is a great generator. They have outstanding documentation, w/ diagnostic sections.

Are those documents on-hand? Have the steps been followed? What has been discovered?

More information is required.

The first pass through the documentation shows shorted stator, open stator and two shorted diodes as the next step to test.

If there is going to be lots of generator work, then removing the starboard side of the starboard exhaust, from above the manifold will provide much better access. If done, then jam a rag into the manifold exhaust port to prevent stuff from falling into the engine.

It is also helpful sometimes to unbolt the gen from the platform, then rest it on 2x4 boards to permit "easy" sliding around to gain better access.

If the electrical side has failed, then a rebuilt section is a cost-effective solution.

thanks for the reply wingless
do you have a copy of the documents and the steps to follow to diagnose my generator

[wingless]

Yes, I have both the PDF and the hard copy versions of all the documents.

The 7.0 BCGB Westerbeke documents are at this link.

Check to see if you accdently shut the breaker on the unit off. On the unit. On is normally up. If you check things out it is easy to accidentally bresh by them and turn them off.
