Hi all,

This is my first post. I spend most of my time on Full Size Chevy forums because that is what I own. However, as my dad and his truck get older, I find myself working on his 1989 5.8L F-250 quite a bit also. I know it may be sacrilege to say this, but I like both Ford and Chevy trucks.

In the past I have used this forum to help troubleshoot other problems on my dad’s truck – I decided it was time to register.

Enough babbling – on to the topic at hand:

Can anyone look up an electrical schematic for my dad’s truck that would show the circuit that includes the under-hood light? I have checked the bulb and the sensor and they both work fine. However, the wire that feeds power to the circuit is never hot. I pulled it apart at the green connector and it never has power. I just need to know where this is fed from so I can figure out why it is dead.

Thanks all,

Tinkerer

 

my manual is not so god but it looks like power comes off the headlight switch.

 

It is on the right side of the diagram:

mangopug and subford - Thank you very much for your responses.

subford - I have found some of your past posts very helpful in troubleshooting other problems. Thanks for sending this schematic. I will take it out to my dad's house and see if I can track down the problem. Near the top left side of the schematic, where it says "Fuse Panel - Page 17", do you know if terminal "8" on the 15 amp fuse means it is fuse number 8?

Thanks,

Tinkerer

 

Yes it does.

subford! - Thank you very much!

This should make it very easy to trace the problem.

I owe you.
