Gas guage fuse ? - 2000 Harley Davidson FLSTC Heritage Softail Classic

Most General Motors vehicles have a specific fuse in the fuse box for the "instruments".
On some models, there is also (or instead of) a fuse under the hood of the car inside the black plastic box (which also has fuses and circuit breakers inside it) labelled "instruments".
I'm thinking either the fuse is loose or bad, or the wires to the fuse are loose or bad.
God bless your efforts.

It could be the gauge or the sender, in the fuel tank, or the fuse to the sender. On some Hondas there's a voltage regulator, in the gauge assembly, holding fuel gauge and some others to 8V.

yes

The gas guage does not have its own fuse but instead gets its power from the "integrated power module" that handles power delivery to the entire instrament cluster and beyond. If the guage is in-op,[doesnt work] then you will need to have a few "hands-on tests run to verify if the sending unit in the tank[fuel pump module] is functional or if this problem lyes else-where, wiring problem, bad ground,ect,ect.. One hint would be if the low fuel level l;ight still functions without the fuel guage working,then your problem is NOT in the tank and very likely is in your dash-electrical or faulty guage.

sounds like the main fuse has blew which is under the hood

Sounds like you have blown a fuse check your fuse box and replace any fuses you find. Hope that helps

Try disconnecting battery for couple minutes and see if it starts working again I have done that in the past

Hi, this could be as simple as a blown fuse. It could also be because of failed general parts. i would first check the fuse box to make sure all the fuses are good then, i would check the wire connections on the back of each gauge to see if they may have become lose or separated form the housing.

Sounds like you have a ground problem, i doubt its in the sending units as both gauges are acting strange work, seeing that electricity likes paths of least resistance one gauge could be grounding through another. Bad grounds wreak havoc on electrical systems.

I would check the fuse first, and if that isnt bad, there is a float in the gas tank that sends a message to the gauge to how much gas is in the tank
