Bob Archer Is very knowledgeable marine electrician. Others tried to repair, without success, the very intermittent shore power fault. Bob quickly diagnosed the problem. The boat being older had some subpar repairs and electrical installations through the years. After talking through issues and learning about our budget Bob quickly suggested a plan. To stay within our budget he offered options on less critical parts but the important repairs he urged we should not comprise on. I would strongly recommend his services to others.
