2007 Norge Starter issue

Brian UK said:
You couldn't leave that permanently as the front pilot and rear lights are also powered from fuse B and they would then remain on.

No, it wasn't suggested to be a permanent fix, only an easy method to determine whether the "startus interruptus" fix is going to cure the non-starting. Once the starter button is pushed, just brush the free end of the cable (connected to the battery positive) across the back of fuse B is usually sufficient.

All, here is the latest communications from Larry at MPH reviewing what they have tried so far.


Brad,

I did do the load test on the battery, in fact I tried swapping it out.

I have been doing some digging myself. I looks like a bad ground may have been the under laying issue. I've been told a bad ground will blow the ECU. When I out the ECU from Guzzi tech in last week I got the ECU disconnect icon. Regardless of what I did I could not lose it. I spoke to Todd and he says the unit was good when it left there. Since I have no way of bench testing the ECU I have to rely on his thoughts. I put your ECU back in and now I am getting the same ECU disconnect icon. Which gives me more to go on. What I've come up with is a bad ground. I had already checked for that, one of the first things I checked. However the ground for the ECU didn't go directly back to the battery, it does now, but I fear the damage is already done. I am waiting for Todd, Guzzi Tech to get back to me, I want to overnight your ECU as well as his ECU to him to have them tested and reflashed, hopefully that will correct the issue.

Interesting to see what they find with the ECU. A bad ground at the ECU can cause issues but would take a lot to blow the ECU in that situation, but guess it is possible. Good to know it was not the battery.

Other thing they may want to look at is the maintenance relay (pretty sure the 2007 has one, but not 100%). It will also cause a no start issue if it is bad. Basically it will not allow the bike to start if it is not triggered. It is there to restrict a start in a low voltage situation. Since it does not sound like a low voltage situation, it may actually be an issue with the relay. Worth a look just to be sure.
 
It takes awhile to jog my memory, but I did recall while rereading this thread -- and, especially, about the earth/ground issue -- that early Norges (and mebbe vB11's, too) had a known ground problem where, IRCC, the negative cable attached near the starter. Was a mild PITA too get to that on the Norge, and I remember checking mine and finding it tight. Many were not.

Now back to knowledgeable folks ... ;)

Bill that is a common problem on a lot of the Carc bikes. The ground lug sometimes doubles as a nut for the starter cover. That is an issue on the Stelvio. Sometimes when you unscrew the starter cover bolt, the lug can come loose. Not sure if the Norge has the same issues, but that is a common place for a grounding issue.

i have a 2007 Norge that makes a loud click when starter is depressed. I have added the starter relay fix already. If I connect alligator clip to positive on battery and yellow wire of starter relay she fires up. It's been at MPH shop in Houston since August, 31st and they haven't figured out either.
I can email a video of sound if anyone wants to hear it, can't figure out how to post it here.

Hey @Brad, have you or MPH ever found the problem with your bike? I am interested in what the fix was, as I am working on a friend's bike with the same problem.

I have stated this time and time again. Almost without exception, this is the primary culprit of this problem.

Me too... but everyone loves to chime in and tell me how their old battery is still good, and they haven't had any problems. YMMV.
 
I figured my friend's bike out. The battery was testing good all day long. The bolt that holds the negative cable to the battery was too long by about 0.02mm, leaving the feeling that the bolt was tight, meanwhile the ground cables were barely touching the battery post. It's been starting all day long. Thank you to this group for the inspiration to search in the unconventional areas.
