A friend of mine has a Honda quad. He told me that it’s starter motor has gave up a ghost. Naturally I had to crack it open. During dissassembly process turned out that my buddy had rolled the quad upside down a couple of times which explains the motor oil inside of starter motor. After some cleaning it was okay, except brushes which were totaled.
Especially the another one. It looks like there has been some sparkling if I interpreter those craters right.
My friend ordered the spare parts and a couple of days later them arrived.
During the assembly process we cleaned the anchor’s contact pads with sandpaper and a cordless drill. Not worthwhile compare to the lathe, but with limited resourses one must do what is doable..
Of course test drive went south. At first it started and ran fine, but during the second flight it stopped and did not started at all. No power, no nothing. A closer inspection told me that somebody forgot to connect the ground wire to the motor. After reconnecting the quad ran fine and we back in business. Hooray!
