Tach and speedometer not working battery light and engine light and red key are on the lights on these gauges will not go off where mileage is read it reads 6 us er

The red key indicator is to do with your security system. When you turn the ignition on and put the handlebar control to the "RUN" position, power is applied to the fuel pump inside the fuel tank, that is probably the sound you are hearing.
The red key indicator usually flashes to show that the system is armed.
If you have a problem the only way to really find out whats going on is to have a dealer check the bike for trouble codes, this is usually done by connecting a computer to the data plug on your bike (this connector is usually found under the seat near the battery).
Hope some of this helped.

most often these problems are solved by mending the wires going in and out of headlight or faring assembly. They can get worn or pinched during service, or bulb replacement etc.

Locate & route Black lead to ground / 2004-later softail: On the frame strap under the seat directly in front of the battery.
Locate & route the pink lead to Signal / For 2004 & later FXST/C/I The #3 cavity in the connector {39b} on the back of the speedometer. The socket terminal on the signal (pk) lead fits the #3 cavity.
Locate & route the Orange and white lead to power / Ummm.. it's saying for 2004 and later to adapt to the fuse block For earlier [ For 1996 to 2003 softail: locate the power lead (o/w) in the tail lamp pin connector {7a} under the seat behind the right rear corner of he battery.] "here you are looking to run it to a fused line, not directly to power/battery" I hope this helped.

Check wires by neck and under tank,some folks have had problems with wires breaking. ignition switch is another area to check
SOURCE: what is the proper PSI reading on a oil pressure gauge when
Oil pressure on a Harley. This is a subject of a lot of different ideas. So, I'm going to tell you this, if your oil light ain't on, don't worry about it. When people come into my shop wanting an oil gauge put on, I ask them they want to scare themselves like that.
A Harley Davidson is built using roller bearings and needle bearings on the crank. Unlike the shell type bearings used in other brands of motorcycles, a Harley engine does not hold a lot of oil pressure. It can't due to the roller bearing design. It is a high volume low pressure system. Unlike the shell type bearings used in the other bikes, the roller bearings have a gap between the bearings. When the bearing rolls over the hole in the crankpin, you'll show pressure. When the gap is over the hole in the crankpin you'll show less pressure because the oil is squirting out to lubricate the engine. The oil pressure light TURNS OFF at 4-5 pounds of pressure. The amount of pressure you will read with a gauge is effected greatly by the temperature of the engine as well.
The best way I can tell you judge your oil pressure is to look at it when you first crank the engine cold. It should come to about 50 pounds or so. After the bike warms up and is idling, you may show almost no oil pressure depending on how accurate your gauge is.
Now, you want to know what I trust as an indicator of my oil pressure? My ears. A late model Harley such as yours is equipped with hydraulic tappets. If your oil pressured drops too low, they will start clattering to beat the band. There will be no doubt in your mind that there is something wrong. So, as long as your bike is running smoothly and quietly (for a Harley) ride the fool out of it and don't worry about oil pressure. Just run a good grade of 20W50 oil that is rated with an API rating of CG4 or better for use in diesel engines and you'll be fine.
