Re: Stus-List Yanmar starting
I had a similar problem where I had to punch the start button 6-8 times to get the starter to crank. Had already replaced the starter button. Finally would just click and then go dead; not even the buzzer. Ended up being corrosion inside the sheathing in the battery cables. Cut back a few inches of cable until it was clean and now seems to start immediately. Apparently the corrosion among the copper strands has enough resistance that it heats up and sucks the battery power enough so it won't have the potential to flip the solenoid.

Re: Stus-List Yanmar starting
I had the same problem for a couple of seasons.Would always crank eventually, but those first 2 or 3 presses of the button with just a click were not reassuring.I ended up replacing all my main power cables - 5 in all - I have 2 batteries and a 1,2,All power switch. Purchased them pre made, off the shelf for about $90.Could have been the ground connections, or corrosion along the wires. But decided 30 years was a good life expectancy and renewed the lot. sam :-) 403-617-6280 From: Ronald B. FrerkerSent: Monday, August 12, 2013 8:56 AMTo: cnc-list@cnc-list.comReply To: Ronald B.

Re: Stus-List Yanmar starting
I had this problem recently with my Universal M4-30 and simply removing the ground cables from the engine, cleaning terminals and reconnecting them solved the problem.

Re: Stus-List Yanmar starting
This is the infamous Yanmar click. It happens because Yanmar used cheap wiring on an otherwise good engine. If you poke around on the Internet, you can find lots of pages with people addressing it. On my 2GM20F, it was primarily a crappy fuse box that was positioned near the air filter. Eventually, I also replaced a wire that went from the starter to the solenoid, I think. Anyhow, it was undersized and copper instead of tinned. Once I did those two fixes, the click stopped. Jack Brennan Former CC 25 Shanachie, 1974 Bristol 30 Tierra Verde, Fl. From: Ronald B.

Re: Stus-List Yanmar starting
Yep, I've worked on several Yanmars. Same thing. Two owners had yard replace starter. Problem persisted. I fixed it for an hour's time. Pull apart the harness and Tefgel all the pins, clean and TefGel all the engine wires and battery cables. Definitely clean both ends of the wire from starter switch to solenoid. Think about running a dedicated wire from starter to solenoid. Look for gaps between the insulation and the battery cable lugs. It's a good idea to TefGel any exposed wires at the lugs and add some heat shrink to cover the gap. TefGel the lugs. Dennis C.

Re: Stus-List Yanmar starting
FYI, an auto mechanics trick to find these problems? Use a car jumper cable and alligator clip between negative battery and engine ground, or between positive source and starter solinoid, same as what you find. If you improve starting, clean connections or replace cable. Whatever it takes. Chuck Resolute 1990 CC 34R Atlantic City, NJ - Original Message - From: Ronald B.

Re: Stus-List Yanmar starting
Yes, probably the starter. It could be a couple of repairable things though. I think the most likely is the brushes and commutator. Brushes are pretty easy to replace and the commutator can be polished up. The circuit between the brushes and commutator needs to be solid for the solenoid to have enough current to pull the fork that throws the drive gear into the flywheel. If you want to save a buck or are in dire need you can disassemble and repair the starter but for the time and effort required it is probably better to have it rebuilt or replaced. The wife and I were in a foreign Spanish port when the starter on the boat we were chartering failed. We managed to disassemble the whole starter and cleaned out all the carbon dust and dirt. We cleaned the commutator with the only thing we had, balsamic vinegar. The brushes were worn and needed replaced but the cleaning managed to get us started. You might also check the quality of the connections and wires powering your starter.
