MOPED ARMY

try to disconnect the bad speedo bulbs, one may be partially shorting out sending power to ground.

replace the connecting block near engine with a new one, or wire nuts. the old connecting block is ridiculous in design, and prone to getting alot of muck in it.

examine wiring throughout the bike looking for pinched, or damaged wires. check all connections inside the headlamp casing.

All of mobies use lower watt bulbs than that (6v-8w, 12v-16w aprox.) allthough if anything, that should be brighter. I might be concerned about it draining too much power.

I do not know about that diagram, but I removed a bad switch from my system. I simply looked at what connections where made with the switch in each position, and wire nutted together the wires to replicate the on position.

Good luck

Thanks for the tips Dan...I'll give 'em a try!

imway18,

I took a look at the wiring diagram for your bike - in typical motorcycle / moped style, the diagram shows what gets connected to where, but gives little useful info on troubleshooting. Important details are left out of the magneto and light switch wiring.

What I'd suggest, is checking the AC voltage between the white wire at the taillight, and frame ground. Then compare this to the voltage between the headlamp terminals. They shoud be the same.

If not, you've got a bad (high-resistance) connection in the wiring, probably local to the headlamp bucket, or the associated grounds. It appears that the lightswitch supplies power to both the head and tail lights from a common point - so if the tail is getting good power, the switch should be OK.

If the issue was a headlamp of too high a wattage, I'd expect the tail lamp to also be dim.. since they share a common feed.

Argh, I ran into the same problem last night!!

Did you ever find an answer to this??
