Need help with fuse that keeps blowing

Anytime, most any vehicle with combined front fixtures ( 1157 bulbs )...
If the green turn indicators inside come on with the park lamps,
The fault is lost chassis ground at those front park-turn fixtures.
One could hunt this fault inside until the end of days.
The orange illumination circuit is very often shorted at the radio or ash tray lamp when aftermarket radios are installed.
