2003 RS 1600 Decompression Solenoid Chatter

[jimships]

Help////////////

I am getting a chatter on the decompression solenoid when the key comes on. I am including a pic of the input coming to the solenoid. Once I hit start and engage the starter it goes to pure and solid 11.5V DC.

My questions:

1) Is this chatter wrong? (I think it is.)
2) Does anyone else's bike do this?
3) I am beginning to suspect the source of the power which I believe is the ignition module. What do you think?
4) I replaced the solenoid and bent the spoon to ensure full push. Any other thoughts?
5) I am concerned about the voltage. I have not yet put a battery into it. I am using a big charger for power right now.

Background: I picked up this 2003 1600 RS bike after a carb fire which took out the center of the bike. I am well along on the bike rebuild and am including some progress pics. Finally, the bike is slow spin on start. I have bypassed the relay, rebuilt the starter and check wire continuity.

Any help is greatly appreciated. I am almost out of ideas...

Be careful with that big charger. Some of those chargers will put out over 16 volts when boosting the power. This can lead to frying your ECM.

I'll check it out now. Thanks

Checked out at 13.6VDC

How do you like your Road Star? Regular, or extra crispy?

Luckily the main harness was not toast. I would say lightly brown on the toast. The tank did not light up so that's a plus.

Put a good battery in and try again. The problem is low voltage.IMO
most of the time trying to start a vehicle without a battery and only using a charger or jump start unit will not even start the vehicle. You need to get a battery anyway but you are getting ahead of yourself and throwing money and time at it that that probably isn't needed if you just bought the battery that you will eventually have to buy anyway.lol

You were right Dave and Duke. Chatter ended and heard it fire (on ether) for the first time...ever. Yea. Thanks

As a matter of fact, if you are just using the charger, more than likely it will cause the solenoid to chatter.

Take cover off and look at what its actually doing while its installed on the bike, there's not a lot of info in the manuals on that solenoid, i never could find what tells it to pull off, i would guess rpm but who knows

[jimships]

It is the RPM...that tells it to turn off. I believe it is in the range of 50RPM

Is it the fuel pump you hear trying to pump gas??

[jimships]

No I will post a video of the chatter when I get back to the bike in the next day or so.
