CUCV Switches, Diodes, Relays

[Warthog]

I was looking over the wiring diagrams and wanted to identify all the in-dash relays, diodes and switches. So here you go.

More.........

Updated with horn and flasher diodes.

Switches, diodes, relays, etc.

Warthog...great job...if I may...there is a a diode for the horn, wrapped in tape in the harness above the fuse bloch, near the horn relay...when I got truck, this diode was blown, and gave me grief until I tracked down the little sucker hidden in the tape of the harness...when the b/o switch was in the normal mode, the horn was activated constantly...at least it shook out any corrosion in the horn...Wilf

The ground in pic 10 can also be up on the side of the dash bolted in the small hole that is above the large hole to the left of his ground location. Three of my 1009s and my 1008 are wired that way. Just look for that 6 prong ground 'comb' and you'll find it. BTW, if you have weird dash problems, check there first. If that ground is broken, it will wreak havoc with the dash electrics.

Later,
Joe

man you guys never cease to amaze me with the knowledge sometimes. if there is a bad contact at that ground would it be safe to assume that none of my running lights, horn, or b/o lights would work? i think some moisture might have corroded that contact and thats my whole problem. cant wait to check it when i get home.

 

[Warthog]

And this list is growing.

There are three more Diodes to check. One on the Horn Relay and one each on the Hazard Flasher socket and the Turn Signal Flasher socket.

I'll see if I can get some pictures

Dstang97 found the hazard diode....

turn signal problem

turn signal problem UPDATE only my hazzards work. verified all my lights work, checked fuses, tried 3 different flashers, nothing when i first get into the truck with out turning the key and move the lever the light lights up and does not flash. It should not come on at all. On a unrelated note...

and Captw found the horn diode.

Thanks and keep the tips coming.

I also found that spraying connections down with WD-40 as part of a look over or service saves alot of work later.. ( No I do not own stock in any lubricate company)

What would happen if you just cut all the diode's out?????? I am having a issue with horn, and lights in the dash and drivers rear light light is BRIGHT as **** like if the brake light was on???? Thanks

 

[Warthog]

No need to cut out the diodes unless they are bad.

The light issues are a totally different issue.

This thread is for information only, not troubleshooting.

Just to clarify. Some of the diodes for the truck are nessesary. Some are not.

 

[Sergiopc]

Understood and Thanks...

What is the number of the diodes? The local parts geniuses claim no such beasties exist and Radio Shack can't match it

 

[Warthog]

Looking in the Parts manual, the diode or "rectifier" is part number 12006337. Searching SS for that number comes up with these threads:

Well, that was easy!

I need some help Iam looking for the 2 GEN Relay location is it located by the starter Relay and the STE-ICE Port or is it behind the instrament panel. Thanks Scott O&O

 

[Warthog]

The GEN2 and Voltmeter relay are next to the starter relay. They look the same and have the same wire colors. You will have to test to find the correct one.

 

[mutt1966]

Thanks for the help Warthog

 

[milestone]

Where do you get the replacement diodes? Are their sizes? And is that is 30 year old technology is there a better way? Thanks

In all fairness, the radio shack number isn't a "spec" its only their catalog number. The Term(s) to search google for is "1N5404" or "3 AMP General Purpose Diode". As long as its at LEAST a 3 amp or GREATER Diode then your fine. You can order them by the bushel from Digikey, and they are higher quality than Radio Shack.

 

[Warthog]

If you want a new diode you can buy it elsewhere.

Diode part number 1N5404 which replaces the GM part number of 12006377 and NSN 6145-01-192-1643

Here is one location. You can order the minimum of 1 or 1250

http://www.digikey.com/product-detail/en/1N5404/1N5404FSTR-ND/975909

And if Radio Shack has them in stock: Part number 2761144
