I´ve searched around the forum, and found several threads on this subject. However, I feel that some of my questions regarding this is still unanswered.
I have a 1997 Superjet that failed to charge the battery while riding. A couple of hours of riding, stopping and starting, it would slowly lose it´s juice till the battery eventually drained. I did measure the stator including lighting coil as stated per workshop manual, and all reading were within spec. However, the stator was not looking good, so I decided to replace the stator with a brand new anyway. As the battery was having some years on it, I decided to replace the battery as well.
I put everything together, but when hitting the starter button it would not fire up. The starter was working and the engine cranked, but would not start. I tried to pour fuel directly into the carbs, but still no go. New spark plugs, checked for spark, all good. Fuel lines are correct, and I can see fuel is flowing through the lines. I tried to hold my hands over the carbs to choke them, but still no luck. I was having a break, and when I came back and tried to start it again, the starter would not turn and suddenly the relay / solenoid just clicks.
So to me, it seems that I have two issues going on:
1. Something mechanical is hindering the superjet from starting ie. fuel, spark or so.
2. Something electrical is hindering the starter to spin.
Before I can attack the issue number one, I have to solve the starter / relay issue.
My first thought was that I might have been put the starter to too much stress when trying to get it started and that I might have burnt the starter. However, it requires some time to replace the starter, and a lot of money for a new OE starter, so I want to check the easier stuff first.
I have done following troubleshooting steps:
1. Switched to battery of my 2008 Superjet which I know is good, same result.
2. Switched to another starter relay / solenoid, same result.
3. Measured 12.7 voltage on battery side of the starter relay. When hitting the starter button I measure only 4 or so voltage on the starter motor side of the starter relay. However, when I disconnect the starter cable from the relay, I measure 12,7 voltage on the starter motor side when hitting the starter button. In other words, there is serious voltage drop when hitting the starter button when the starter motor is connected. Does it mean that the starter engine might be seized and pulling too much, or may it be other issues I don´t think of?
Any ideas?
