HSATF Tail Gunner Posts: 96 06/11/08 12:26 PM	Tags : None Over the weekend I went for a 300 mile ride and when I went start it on Monday for my commute, it would not turn over. It did not buzz. I just turned over once and stopped. Tried again, and got the same results. I thought my Yusa battery (a year old) was failing, and I put a trickle charger on it. Next day, same problem. I jumped the battery from my other bike and got the same results. I disconnected the battery terminals from the battery on the bike and jumped it that way, and got the same results. It is not the battery, so it seems like the starter. I will bypass the solenoid and see if that makes a difference. Does anyone have any other ideas? this is a 2000 Tourer with 20,000 miles.

It could be the solenoid, starter button, interlocks, etc although only the solenoid and cables would prevent a good flow of power that might cause the starter to only turn over slowly once. Just to rule out a locked up engine, try turning it over by hand on the crank bolt or push starting the bike. If you have a clamp on ammeter, that can also help diagnose the problem. I've never looked at the procedure for removing the starter, but if it's not too bad, you may want to remove it and bench test it (just apply power to it via jumper cables). This will tell if the starter is completely shot, but not if it is weak. You local auto parts has a starter tester and may be able/willing to help you check it too. There aren't many instances of the Shadow starter going belly-up so it would be unusual if that turned out to be the problem. duke loud horns save lives

Many times I've found loose or corroded connections preventing a full shot of electricity from getting through. The electrons flow from negative to positive so often when diagnosing starters my first connection is from the negative battery post to the starter housing or somewhere very close by. I also look at the voltage drop across the batt posts. If the voltage drops a significant amount when you depress the starter button and stays dropped for as long as you hold the button I would think that power may be getting all the way to the starter. If the voltage drops and then returns to 12+ while you are holding the button, or returns to full voltage just after that "half turn" of the starter then something is dropping out. This is "quick and dirty" troubleshooting but it helps save time in the field........ from golf carts to bulldozers to 100 ton dump trucks. Holding the starter button and hitting the bottom of the starter housing with a 3 lb hammer may jog it off the flat spot and get it turning. If the starter weighs 80 lbs and has 4 Cat batteries on a 24 volt system. For a T a 12 oz hammer will do. IMHO

If that turns out to be the case, I will switch my efforts to my other bike, which has some less severe problems (I like to have one bike in the stable that can run, so I can still ride when I want/need to). You would think with two bikes, I would have better luck keeping one running! Thanks Alan, I will keep your comments in mind.

HSATF Tail Gunner Posts: 96 06/14/08 9:55 AM	Well the good news is that the starter is not the problem (so you where right Duke!). I jupped the starter and it immediately started the engine. The bad news is that I have not found the cause yet. Tony, I will heed your advice, as it sounds like an easy thing to check.

HSATF Tail Gunner Posts: 96 06/14/08 11:26 AM	Well it seems to be a loose connection for the starter relay control circuit. I removed the connector to check the main fuse. When I put back on to do the voltage drop tests, the engine turned over normally. It is going to take me a while to trust this bike again. I believe I will stay close to home with it for a while and just use it for my commute.

HSATF Tail Gunner Posts: 96 06/14/08 5:58 PM	Update. My last report was a false positive. Just before I was going to put the seat back on, I thought I would actually start it instead of just making sure it turned over. It did not turn over. I pushed down on that relay connector and tried again with no luck. So I thought I would try Tony's advice and check the starter button. I went to the link the thread Rich had put together. I followed the procedure and added the part about putting dielectric grease on the contacts. It worked like a charm. Tony, you keep saving me with timely advice. Keep it up and thank you.
