Trouble With Installation
By Greg S.
La Junta, Colorado
Purchased 10/02/2017 |
Review Posted 10/18/2017
Hired an electrician to do the install. He's done a lot of generators but not a Briggs. It turns on great, motor smooth & quiet, but won't shut off when the electricity comes back. Can't figure out the problem. If we can then I would recommend it to a friend, but not until.

Sorry to hear that you are having some issues trying to find a local installer that can quote you a lower price. I can send you a list of some more installers in your area that may be able to quote you better pricing but keep in mind that just because the price may be lower it is not always the best option to go with.
