Modern Buddy

2008, Stuck on "E"

Took the aft bodywork off.

Pulled float unit.

I'm assuming I should test continuity between BLK and WHT wires? (Not the BLK ground wire)

Variable resistance between white and black.

No power from black or white coming into float...

Do these scoots have no fuse box?

When I put 12v to the WHT wire at the gauge, should it peg to FULL? No movement...

1 fuse next to the battery, and 1 1 amp fuse for the accessory port. I have a 125 cluster handy. Walk me through what you did at the gauge, I'll duplicate it here.

Fuel gauge has WHT, BLK, and OR wires
Orange is 12v
WHT goes to fuel float
BLK is ground

I connected 12v+ to orange, ground to WHT or BLK, no needle movement, it's stuck on empty.

Seems that you can't buy the gas gauge by itself? Even though it is removable

If I go positive to orange and ground to black, no movement. If I change the ground to the white wire with a black stripe, the needle moves to full.
My gauge off a 2007 has orange, black and white/black

I'd probably roll the dice with this one: https://www.ebay.com/itm/226652814361?_ ... R-CH58_ZZQ

Thanks for your help!

The problem with replacing the unit is, our 2008 has only 1800 miles, which we'd like to keep

It seems that the gas gauge canNOT be separated from the cluster...

Thanks again

You're welcome. That cluster is for a 50cc. On a side note, the odometer is pretty easy to change. Gently roll the wheels.

If you're interested I have a Buddy 125 cluster with a just under 3,500 miles on it I could sell for $50, including s/h.

Ahhhh. It DOES come apart. No cutting etc required. I will check 2 resistors, and look for visible damage.

I might take you up on your cluster, will let you know

I don't know the resistor color codes. But the right resistor tests INFINITE ohms. I'll guess that's the problem...

Ordered some resistors from DigiKey on-line, cheaper than running around to find them

Guessing if you ordered resistors, you figured out the values. If not, here's a handy site to decide them:

I think the gold band delineates tolerance from the expected value.

Thank you, Yes the gold seems to be the tolerance, will find out this weekend if it works
