Ok I need to run an idiot light for my alternator so what are you guys using led incandescent resistor??
I was thinking led but may need a resistor in addition for it to work any ideas
Oh here is a pic of my current set up
A little rough but it gives me 14.5 v
Well, you won't have to squint to tell if that's lit! I think I'd use an incandescent. Been a long time since I had a car with one, but I recall that sometimes it would glow dimly. I think an LED might be all or nothing?
Well here I am the idiot, hi Roy. First I was going to tease you but I got beat to the punch. I found a few examples of this project on google for what they are worth. I'm no expert by any stretch but the one thing I remember when I converted to led brake lites was they wouldn't work until I got all the incandescent out of that (each) circuit. But when I put in my back up lites they worked fine off the shifter switch which was just off a common 12v fuse block. Note that each back up lite (LED) fixture assembly did have a circuit board in them doing something. That's all I don't know, good luck my friend.https://www.google.com/search?q=wiri...w=1129&bih=520

The ones I've read on net guys use a resistor with a led but maybe one is made that has led/resistor all in one

Thank you jimmy
Yes that's I think I need but also need in put on what other guys have used
I ended up using a indicator light for the windshield wiper from my E250 parts truck seams to work just a thought do I need a diode? On a circuit like this
I'm running a single LED bulb for my turn signal indicator. Since I have switched to all LEDs, the flasher unit is a heavy duty, (read that commercial vehicle unit), designed to operate, without issue, on multiple LED bulb systems.
For me, it was as simple as taking the indicator lead from the turn signal switch and running to the single bulb in my dashboard. Single bulbs can be bought all over ebay and through other suppliers. I think I have a couple extra laying here. Let me know if you need one.

Thanks I'm good with what I have, just concerned with back feed from the alternator I don't know very much about magic(electrical)
If the engine wants to keep running after you turn off the key, then you need a diode. Otherwise, not needed. Note that a diode might allow you to run an LED because they have a definite resistance even in the "forward" direction.

Not sure what year your 302 is but my '90 5.0L has a wire from the alternator that used to run back to the instrument panel, and idiot light. I think the wire is green with red tracer or red with green tracer. ( I would have to confirm that.) The incandescant light bulb was parallel connected to the wire with the gauge and then ground. I currently do not have it connected, but do have a wiring diagram for my donor.
