10kw Powertech repair update
Just wanted to share what we found on our 10kw Powertech generator. Back in February while at the King of Hammers race in Johnson Valley California our generator shut down from an overheat condition while we were away. Generator ran fine but no fan and no power output. Luckily we had a portable generator to get us through the week.We finally had time to do some troubleshooting on it a couple weeks ago. Found 5v at transfer switch and fan. When we pulled the end off the generator we found the end bearing a little tight and rough to spin. The Exciter Rotor had made contact with the Exciter Stator. Going through all the troubleshooting steps and ohming everything out we found the Stator was bad. Rotor looked fine luckily.
After a conversation with Jeff at Powertech, we ordered the parts (Stator & End Bearing) and replaced them this morning. Fired up the generator and all is well (Whew and WooHoo)! We really dodged a bullit on this one. According to Jeff the Exciter Stator is the only replaceable part other than electronics. If that didn't work we would have to replace the whole generator head. Total repair was $570.41 parts and shipping. Was a fairly easy repair, even with no knowledge or experience with generators.
Thanks to Barry's Beamalarm site for the manual and troubleshooting guide. And to the Foretravel forum and related posts and info. I felt comfortable enough to tackle the job. I wish I had took pictures and documented the process but in reality it was a simple straight forward remove and replace. Once we saw the damage it was pretty obvious what happened. Hope this info can help someone in the future.
