for beginners, i can't seem to get a pilot light to work off of the big load terminal of the GPR. the pilot lights keep burning up for some reason and i can't figure out why it draws so much current. i am going to try a fused LED tomorrow.
If you wire the bulb, in series with the Load, it becomes a fuse
(I'm not sure I see that in your diagram though) are you Sure it's a 12v bulb?
The same thing is going to apply to an LED but, be aware, because they are NOT 12v devices, you'll need a resistor when wired properly (from the Load side to Ground).
the switch to interupt power to the control side of the GPR seems to work ok but i'm not sure if it's drawing a massive amount of current though so i am going to fuse that one too.
As I said before,,,, that's not the way to do it. The GPs are NOT controlled by applying 12v (that wire has 12v in it the Entire time the key is On), the PCM controls them by applying GROUND. So, your way, if the PCM wasn't supplying that ground, because it didn't want them On, you can't make them come on. BUT, if you supply Ground though the sw, you would have total control. Also, that wire wouldn't require any kind of fuse (that circuit draws Very Little anyway)
i also wanted to be able to manually turn the glow plug relay on also but i'm starting to think that is pointless anyway.
Do you need to override the PCM or is the PCM not turning them on when it should?
