Subject: Re: 12.5 KW Kohler Won't Start Author: Dave Mills [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 07/ 20/ 02, 7:59am In reply to: Dave Mills 's message, "Re: 12.5 KW Kohler Won't Start" on 07/ 7/ 02, 1:43pm Final status. Two or three problems. I fixed weak battery connections. Then the generator would ALWAYS start and stay running only if I held the start button on. It was generating 88 volts. Second problem was a transformer fuse. When the fuse was replaced and the brushes cleaned, the voltage returned to 242 and it started and ran fine.

Mine is doing exactily the same thing. It is in an 85 PT36 and has only 858 hrs. It is seldom used but like all such systems it is essential when it is required. You spoke of a transformer fuse and cleaning the brushs; please explain further. I have looked at the factory service manual and find no mention of a transformer or a controling fuse nor any guidance for the brush cleaning procedure. For your info, I did determine that the control box contains three small relays and one large one. These relays all control the start sequence, generator exciting and then when the generator spins up and begins to develop AC power the large multi-function relay is latched(via AC) allowing the engine to continue to run while preventing the starter from operating, etc. I replaced all of these relays as they are relatively cheap and easy to access; this provided some benifits; the problem in now only intermittant, not continual. Please provide what ever follow-up you can and perhaps others will also comment. Thanks, Neil [ Post a Reply to This Message ]
