Re: Queston on TR Delco Alternator wiring diagram
I've been asked this before, and I finally have the answer.
You have the wiring diagram from one install (Generic, the one you should be using), and the written instructions for a specific install for someone.
I know on at least one occasion I confused the issue by posting them together, and it may have happened more than once.
Sorry. My fault.
Follow the directions on the diagram I'm posting now.
It's real clear, and the #2 wire should go to the Horn Relay 'Hot' wire, or an equivalent.
This will give the regulator a proper reading of system voltage requirements.
I know this is confusing to some people, and even more so sense I got the wrong instructions out at one point, so , again, you have my apologies.
MAKE SURE YOUR 'IDIOT' LIGHT ISN'T GROUNDING THROUGH IT'S BRACKET!!
This is the #1 reason most installs don't work the first time.
You must get a light bulb socket that has two wires, and has a controlled ground.
If it can ground through it's bracket, it's useless.
For alternator testing, you can hook battery power up to the 'BATT' terminal, and then connect the #2 terminal to it.
THIS IS FOR TESTING ONLY! Do NOT run your alternator this way other than for testing.
You may not be getting enough resistance from your 'Idiot' light.
It takes about 150 Ohms min. to do the job. You may want to put a 1 watt- 150 ohm resistor inline with your idiot light to make sure.
The resistor can work just fine as a replacement for your light too, if you don't want to use the light, or can't find the correct light right now...
A resistor or light is also good for a test wire if you put one between the #1 terminal and the 'Batt' terminal.
DO NOT RUN YOUR ALTERNATOR THIS WAY EXCEPT FOR TESTING.
