Speedometer is being glitchy
2006 HD Sportster XL883C
My speedometer is being weird. It is not working and sometimes when I start it up it jumps to a random speed snd slowly goes back to zero or won't budge at all. It started after my battery died and never started back working after installing a new battery. Any ideas of how to fix this? Thank you

I had my speedometer do similar when my regulator has gone out on other motorcycles, bad regulator will also make the battery seem bad. Just a WAG.
Should be testing procedures in the manual, I am at work now, I'll try to remember to look them up when I get home.

Many times it is a loose or weak battery condition, or poor ground.
Most often, the glitchy electronic sportster speedometer is fixed by tightening both screws on the battery.
The contact points are small, the sporty vibrates a lot, and the screws are std thread, not fine.
Ill bet bet that will fix your problem.

ok. I took the connectors off and back on. Now my neutral light is not coming on and the speedometer went to the furthest right it would go. I have a battery tender connection there. Could that be messing with my connect?

That is bizarre.
In all my sportsters, I’ve never had one pegged right. Reverse polarity?
I don’t see how neutral sensor or the light could be connected to the removal of the battery cables unless you grounded the positive on the frame before you removed the negative.
If the battery tender cable was compromised, that would be a short, smoke and fire to follow. That’s probably not the issue.

Yeah. I was careful with removing the battery. Took the neg off first and then the pos. It's a pretty new battery. Connectors look clean

I did notice the speedometer clicking when i was reinstalling the battery. It makes an odd clicking noise when I turn the key on and off and then the speedometer jumps.

Check all your earth wire connections, there is one at the back of the primary near the starter motor, one at the back of the gearbox and one on top of the gearbox where the battery earth cable connects.
