On a 74, what fuse would you run your hot lead from to power a stereo? Or would it be better to set up a dedicated, fused/switched lead directly from the battery?
My worry is when I add my stereo and an amp, I will be overtaxing the old system. Ideas? |

You have main 3 choices:
1) Connect to constant power. (recommended) Find a fuse (11 or 12) with an extra terminal. Connect an inline fuse there and run to both red and yellow wires of new radio. Just remember to turn off the radio when you park. 2) Rig a toggle switch and do as above but put the toggle between the inline fuse and the new radio wires. This will allow you to turn off all power. Place the switch only on the red wire from the new radio to keep the clock and preset memory of the new radio. 3) Connect to switched ignition power. NOT RECOMMENDED. The radio will turn on and off with the key however you risk burning the poiints. There is no accessory position to the ignition switch. If you have carbs, the fuel pump will run. |
