Trouble with lights

Hello I have a 1974 F-250 4x4.What I'm having trouble with is it starts and runs. But I have no heater wipers dash lights or radio. I checked fuses and there all ok. Has anyone had this trouble or something like it?

thanks

How did you check the fuses? Did you actually remove them and perform a continuity check? Do you have power on BOTH sides of the fuse with it installed with the key in the appropriate position? If you don't own a multimeter, consider the fuses unchecked.

Those circuits should all be "ignition on" only correct, fmc? well, except for dash lights, those should be "constant hot", like the headlights since they are controlled by the light switch. Dash lights could simply all be burned out, and not related to the other issues, but a tester would confirm whether power is actually making it to those particular fuses......

That's correct. Wipers and radio are available during RUN or ACCY; heater should just be in RUN. Dash lights are controlled through the headlight switch, which has hot-at-all-times available.
