diode for wiring to gen 2 light. Where is it?

[ida34]

I am trying to track down the cause of no gen 2 light on one of my cucv's. The wiring diagram shows a diode and this is the only thing I have yet to check. The relay checks out and all the it is triggering properly. I really think the diode is the problem but where is the damn thing?

Thanks

Could be one of those plug in units on the left fender well... I have never replaced one..though...The 20 and 34 give good schematics.

left? please use drivers or passengers, makes it much easier.

and my Gen 1 light has not worked since i've owned the truck, but it still charges, so i dont worry about it.

They will charge but not till you get the revs up. The alt will not energize until the engine is reved up without the light. I drive alot of stop and go so I need them to charge at or near idle too.

 

[CCATLETT1984]

the easiest way would be to just put a resistor on the sense wire, like the civilian apps used. so even without the light working there will be enough draw to start it charging.

I have had a lot of trouble with corrosion in the light sockets in the dash. I ended up pulling the dash out and cleaning all of the contact points.

The dash is good. I want to get it working right with a working light so I will chase down the diode. When I locate it I will post. The dash socket has no problems. I have already checked it. Thanks for the responses.

Did anyone happen to locate this diode? I'm going through a system now and need to test it.

I still have not had time to mess with it.

For everyones info, the GEN2 diode is behind the dash above the heater control, next to the windshield. Only way to access it with the dash removed.

Me too. I found out that my second alternator was not charging the battery because of the cluster corrosion. Charging better than ever after pulling the cluster and cleaning the printed circuit connections and the sockets.

The Diode for Gen 2 is behind the voltmeter
