Thundermax Issue---Need Help
So lately zippers made a software upgrade with new maps added.
With my old map I never had an issue (I also made sure I have the correct speedo claibration numbers for my bike).
Once in a great while when I ride the speedometer wont work, Battery light will go on, engine light, and the security key light will go on. Once I restart the bike the problem is fixed.
Barley happens, but still it bugs me.
ANYONE HAD THIS PROBLEM?

Not having issues on my T-max. It sounds like a ground issue to me, but what do I know?
I'd check your dielectric grease in your connector and see if you have a bit of moisture or corrosion messing with you.
If not, give your gremlin bell a wiggle.

I had that problem happen twice. Called Zippers and they said the ECM loses communication. They recommended using dielectric grease on the main plug and if possible put on a cable tie to keep the 2 parts tight together. No problems since.
While I was at it I also cleaned up the fuses and relays and gave them a coat of grease.
Don't forget to pull the ECM fuse before you disconnect the plug.

Second, sounds like a loose battery connection. Could be you disturbed an ailing connection while messing with the TM this time. Try taking the battery leads off, clean things up and reassemble tightly.
