well your batt light is on cuz the alt, you probably knew that already. check your vehicle speed sensor if there are no fuses blown, you may have damaged that.

my speedo went out when my alternator bolt snapped but that caused much more worse problems than that. I'm still leaning towards blown fuse on this one.

AHHH!
you got to it before i did.
its ur VSS..... its fried..... i just had my VSS replaced and my car speedo/odo works perfectly (i believe its located right next to ur tranny, so you could have fried it while u were welding)
symptoms:
1. speedo doesnt work, but rmp/gas/temp works
2. ur odometer froze...it stopped recording miles
3. ur rpm fluxuates at idle, like its about to die/stall out
4. CEL code: P0500 - Vehical speed sensor manfunction

so the only thing that is causing my speedo not 2 work is the vss fuse being blown i guess.. all lighst work. but speedo dosent move. its lights up still. but also odometer dosent move either.

i had the same problem, your going to laughe when i ask you this but do you have any type of homemade 02 simulator on your car, cuz if so it can push your 02 sensor onto the body of your car and it grounds the 02 sensor. I guess when its grounded like that it blows your alternator light which in return does not allow your spedometer or odometer to work. I had a hondatech tell me this straight in person.
