When you were measuring the voltage on the blinker wire are you sure that the voltage was a positive 5.9V and 6.8V? If it were a negative voltage then you have a bad ground somewhere between one or more marker lights and the cars battery. Most likely the bad ground will be right at the marker light socket.
If it really was a positive voltage, then try unplugging the tail light bulbs and measuring again as the tail lights are another place where both the parking light and blinker circuit come together. The front parking lights are also another place, but in a previous post you stated that disconnecting the digitails blinker wire did not prevent the dash indicator bulbs from lighting so that means the digitails probably are not at fault.

Do you mean if it is negative voltage, it should show (-) sign next to the value on the voltmeter screen?
The voltage I got did not have any (-) negative sign on the screen.
I have just read in one of the painless wiring manuals that if there is a bad ground, it will find it is way to another source like the indicators on the dash cluster.
I will check the wiring again at the side marker and the parking light housing again
