I found your site while looking for parts, nice site.I have an electrical problem,thought some one might be able to help.I have a 74 620 standard cab 4 speed L18 motor.I had all the lights working,but now the head lights are'nt working.Using a volt meter there is'nt enough voltage to register on the meter.If you use a probe the light is very dim compared to all the other checks. Any help on this problem would be appreciated.

Sounds like you might have a dead short in the wireing some where. If you changed the fuse and it's still dim. Then you have a short or a bad light switch.
