  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

An issue I haven't run in to before.

Well, I replaced all the wiring to the starter and battery, just to be sure. might as well while I am in there...

Pulled the starter, took it apart, and nearly wept.... it was FUBAR inside. magnets had broken free and were sliding around.

So I pulled one from my old GS650G engine and examined it. Almost identical, except near pristine inside.
X-refed the parts with my new program, not crossable, but the 650G starter is used in the 1100G and the 1000L as well as a whole range of others (850,750,450,300). So it has the power to do the job. Shaft is identical in every way. The only difference is that the rear plate is not the same, different mount points.

So i swapped the plate from the 1100E's broken starter to the 650G's good one. perfect fit. Starter is a perfect fit in the bike. I will finish the install and wiring tomorrow and let you know how it goes!

As of this moment, it appears that if you swap the rear plate, you can interchange the starters from many bikes!

Most interesting! Good luck ... sounds like you're gonna be just fine, though!!

There are other differences in the starters as well. Usually the 1100 starters have 4 brushes in lieu of 2 brushes. The 4 brushes are used to carry the additional starter power required by the larger displacement and higher compression engines.
I am glad your problem as been correctly identified!

The starter that came off the 1100 had 2 brushes, just like the one that came off the 650.
Your post makes sense, anyone with an 1100E starter care to see if I had the wrong starter to start with?

Can't vouch for an 1100E, but the starter on my 1100G has four brushes.

Getting a tad irritated.

Replaced all wiring, from the battery to the starter, on positive and negative sides.
No change.

Tried a straight wire from pos to starter, still cranks slow.

Gonna grab a set of starter brushes with 4 brushes and try again. Maybe the P.O. put the wrong brushes in and it has always been a dog to start sometimes. Would explain why he came down from $2200 to $1100.

I WILL win this battle. No GS has defeated me yet! Except that 650 sitting in the garage in pieces... it has put a whuppin on me a couple of times...

A HA!! having a two brush starter will cause your problem as it is a much lower torque starter.
 
Y'all ain't gonna believe this.

Primary issue: Apparently a dead rectifier.

Compounded: My charger died. it produces no current, though the gauges say it's doing it's thing. All my "good" charged batteries were dead as a doornail. The new battery started good, cranked well for a bit as reported, then bogged down again.
AARRGGHH!!

New charger, starts fine, recharges fine from charger. Dies when not. The Official GS Resources electrical t-shoot guide points at rectifier. As post # 2, 4 , 8, and 17-23 inclusive suggested.

But the starter swap from the GS650 to the GS1100 has worked without a hitch. I'll call that useful data learned.
 
Update: New rectifier fixed it, and it purs like a kitten. A 27 year old air cooled kitten, but a kitten nonetheless.

And the starter swap was flawless. Writing up for tips and tricks today.
 
Outstanding! Glad to hear you finally solved it ... Don't you just hate when completely unrelated problems mysteriously come together to make what should have been an easy diagnosis damn near impossible?

you got that right.
Was that off an 1100e? It was very different, physically, than the one that was on there. I'm thinking the previous owner had put on one that 'worked' for a bit, but was too weak to hold up for any length of time. Was much smaller than the one I installed to fix it. Same wiring pattern and colors... just tiny by comparison.

I took it off my 80 GS1100L. It had junkyard yellow writing on it so I'm not sure what model it was off of. The PO must have already changed out the original one.
